Chapter 2
Connecting with ProLink II Software
2.1 Overview
ProLink II is a Windows-based configuration and management tool for Micro Motion transmitters. It
provides complete access to transmitter functions and data.
This chapter provides basic information for connecting ProLink II to your transmitter. The following
topics and procedures are discussed:
Requirements (see Section 2.2)
Configuration upload/download (see Section 2.3)
Connecting to a Model 1500 transmitter (see Section 2.4)
The instructions in this manual assume that users are already familiar with ProLink II software. For
more information on using ProLink II, or for detailed instructions on installing ProLink II, see the
ProLink II software manual, which is automatically installed with ProLink II, and is also available on
the Micro Motion web site (www.micromotion.com).
2.2 Requirements
To use ProLink II with a Model 1500 transmitter with the filling and dosing application, the following
are required:
ProLink II v2.3 or later, for access to the filling and dosing application
ProLink II v2.5 or later, for access to meter verification
The appropriate signal converter and cables: RS-485 to RS-232 or USB to RS-232
- For RS-485 to RS-232, the Black Box® Async RS-232 <-> 2-wire RS-485 Interface
Converter (Code IC521A-F) signal converter is available from Micro Motion.
- For USB to RS-232, the Black Box USB Solo (USB–>Serial) (Code IC138A-R2)
converter can be used.
25-pin to 9-pin adapter (if required by your PC)
2.3 ProLink II configuration upload/download
ProLink II provides a configuration upload/download function which allows you to save configuration
sets to your PC. This allows:
Easy backup and restore of transmitter configuration
Easy replication of configuration sets
Micro Motion recommends that all transmitter configurations be downloaded to a PC as soon as the
configuration is complete.
Parameters specific to the filling and dosing application are not included in the upload or download.
6Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Connecting with ProLink II Software
To access the configuration upload/download function:
1. Connect ProLink II to your transmitter as described in this chapter.
2. Open the File menu.
To save a configuration file to a PC, use the Load from Xmtr to File option.
To restore or load a configuration file to a transmitter, use the Send to Xmtr from File
option.
2.4 Connecting from a PC to a Model 1500 transmitter
ProLink II software can communicate with a Model 1500 transmitter using Modbus protocol on the
RS-485 physical layer. There are two connection types:
RS-485 configurable connection
SP (service port) non-configurable (standard) connection
Both connection types use the RS-485 terminals (terminals 33 and 34). These terminals are available
in service port mode for 10 seconds after transmitter power-up. After this interval, the terminals revert
to RS-485 mode.
To make a service port connection, you must configure ProLink II appropriately and connect
during the 10-second interval after transmitter power-up. Once a service port connection is
made, the terminals will remain in service port mode. You may disconnect and reconnect as
often as required, as long as you continue to use service port mode.
To make an RS-485 connection, you must configure ProLink II appropriately, wait for the
10-second interval to expire, then connect. The terminals will now remain in RS-485 mode,
and you may disconnect and reconnect as often as required, as long as you continue to use
RS-485 mode.
To change from service port mode to RS-485 mode, or vice versa, you must cycle power to the
transmitter and reconnect using the desired connection type.
To connect a PC to the RS-485 terminals or an RS-485 network:
1. Attach the signal converter to the serial port of your PC, using a 25-pin to 9-pin adapter if
required.
2. To connect to the RS-485 terminals, connect the signal converter leads to terminals 33 and 34.
See Figure 2-1.
3. To connect to an RS-485 network, connect the signal converter leads to any point in the
network. See Figure 2-2.
4. For long-distance communication, or if noise from an external source interferes with the
signal, install 120-ohm, 1/2-watt resistors in parallel with the output at both ends of the
communication segment.
5. Ensure that the transmitter is disconnected from a host PLC.

Flowmeter Startup
3.1 Overview
This chapter describes the procedures you should perform the first time you start the flowmeter. You
do not need to use these procedures every time you cycle power to the flowmeter.
The following procedures are discussed:
Applying power to the flowmeter (see Section 3.2)
Performing a loop test on the transmitter outputs (see Section 3.3)
Trimming the mA output (see Section 3.4)
Zeroing the flowmeter (see Section 3.5)
Note: All ProLink II procedures provided in this chapter assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 2 for more
information.
3.2 Applying power
Before you apply power to the flowmeter, close and tighten all housing covers.
Turn on the electrical power at the power supply. The flowmeter will automatically perform
diagnostic routines. When the flowmeter has completed its power-up sequence, the status LED will
turn green if conditions are normal. If the status LED exhibits different behavior, an alarm condition is
present (see Section 5.4) or configuration of the filling and dosing application is not complete.

Flowmeter Startup
3.3 Performing a loop test
A loop test is a means to:
Verify that the mA outupt is being sent by the transmitter and received accurately by the
receiving device
Determine whether or not you need to trim the mA output
Select and verify the discrete output voltage
Read the discrete input
Perform a loop test on all inputs and outputs available on your transmitter. Before performing the loop
tests, ensure that your transmitter terminals are configured for the input/outputs that will be used in
your application (see Section 4.3).
ProLink II is used for loop testing. See Figure 3-1 for the loop test procedure. Note the following:
The mA reading does not need to be exact. You will correct differences when you trim the mA
output. See Section 3.4.
WARNING
Upon transmitter startup or abnormal power reset, any external device
controlled by a discrete output may be momentarily activated.
Upon transmitter startup or abnormal power reset, discrete output states are
unknown. As a result, an external device controlled by a discrete output may
receive current for a brief period.
When using Channel B as a discrete output:
You can prevent current flow upon normal startup by setting Channel B polarity
to active low (see Section 4.6).
There is no programmatic method to prevent current flow for Channel B upon
abnormal power reset. You must design the system so that a brief current flow to
the external device controlled by Channel B cannot cause negative
consequences.
When using Channel C as a discrete output, there is no programmatic method to
prevent current flow upon either transmitter startup or abnormal power reset. You
must design the system so that a brief current flow to the external device controlled
by Channel C cannot cause negative consequences.

Figure 3-1 ProLink II – Loop test procedure
3.4 Trimming the milliamp output
Trimming the mA output creates a common measurement range between the transmitter and the device
that receives the mA output. For example, a transmitter might send a 4 mA signal that the receiving
device reports incorrectly as 3.8 mA. If the transmitter output is trimmed correctly, it will send a
signal appropriately compensated to ensure that the receiving device actually indicates a 4 mA signal.
You must trim the mA output at both the 4 mA and 20 mA points to ensure appropriate compensation
across the entire output range.
ProLink II is used to trim the mA output. See Figure 3-2 for the mA output trim procedure. Note the
following:
Any trimming performed on the output should not exceed ± 200 microamps. If more trimming
is required, contact Micro Motion customer support.

3.5 Zeroing the flowmeter
Zeroing the flowmeter establishes the flowmeter’s point of reference when there is no flow. The meter
was zeroed at the factory, and should not require a field zero. However, you may wish to perform a
field zero to meet local requirements or to confirm the factory zero.
Note: Do not zero the flowmeter if a high severity alarm is active. Correct the problem, then zero the
flowmeter. You may zero the flowmeter if a low severity alarm is active. See Section 5.4 for
information on viewing transmitter status and alarms.
When you zero the flowmeter, you may need to adjust the zero time parameter. Zero time is the
amount of time the transmitter takes to determine its zero-flow reference point.
•A long zero time may produce a more accurate zero reference but is more likely to result in a
zero failure. This is due to the increased possibility of noisy flow, which causes incorrect
calibration.
•A short zero time is less likely to result in a zero failure but may produce a less accurate zero
reference.
The default zero time is 20 seconds. For most applications, the default zero time is appropriate.
You can zero the flowmeter with ProLink II or with the zero button on the transmitter.
If the zero procedure fails, see Section 11.6 for troubleshooting information.

Additionally, if you have the enhanced core processor and you are using ProLink II to zero the
flowmeter, you can also restore the prior zero immediately after zeroing (e.g., an “undo” function), as
long as you have not closed the Calibration window or disconnected from the transmitter. Once you
have closed the Calibration window or disconnected from the transmitter, you can no longer restore
the prior zero.
3.5.1 Preparing for zero
To prepare for the zero procedure:
1. Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes.
2. Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
3. Close the shutoff valve downstream from the sensor.
4. Ensure that the sensor is completely filled with fluid.
5. Ensure that the process flow has completely stopped.
3.5.2 Zero procedure
To zero the transmitter:
With ProLink II, see Figure 3-3.
With the zero button, see Figure 3-4. Note the following:
- You cannot change the zero time with the zero button. If you need to change the zero time,
you must use ProLink II.
- The zero button is located on the front panel of the transmitter. To press the zero button,
use a fine-pointed object that will fit into the opening (0.14 in [3.5 mm]). Hold the button
down until the status LED on the front panel begins to flash yellow.
CAUTION
If fluid is flowing through the sensor, the sensor zero calibration may be
inaccurate, resulting in inaccurate process measurement.
To improve the sensor zero calibration and measurement accuracy, ensure that
process flow through the sensor has completely stopped.

If the transmitter, core processor, and sensor were ordered together, then the flowmeter has already
been characterized. You need to characterize the flowmeter only if the core processor and sensor are
being paired together for the first time.
4.2.2 Characterization parameters
The characterization parameters that must be configured depend on your flowmeter’s sensor type:
“T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed
in Table 4-1. The “Other” category includes all Micro Motion sensors except T-Series.
The characterization parameters are provided on the sensor tag. The format of the sensor tag varies
depending on your sensor’s date of purchase. See Figures 4-2 and 4-3 for illustrations of newer and
older sensor tags.

Density calibration factors
If your sensor tag does not show a D1 or D2 value:
For D1, enter the Dens A or D1 value from the calibration certificate. This value is the
line-condition density of the low-density calibration fluid. Micro Motion uses air.
For D2, enter the Dens B or D2 value from the calibration certificate. This value is the
line-condition density of the high-density calibration fluid. Micro Motion uses water.
If your sensor tag does not show a K1 or K2 value:
For K1, enter the first 5 digits of the density calibration factor. In the sample tag in Figure 4-2,
this value is shown as 12500.
For K2, enter the second 5 digits of the density calibration factor. In the sample tag in
Figure 4-2, this value is shown as 14286.
If your sensor does not show an FD value, contact Micro Motion customer service.
If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density calibration
factor. In the sample tag in Figure 4-2, this value is shown as 4.44.

Flow calibration values
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character
FT value. Both values contain decimal points. During characterization, these are entered as a single
10-character string that includes two decimal points. In ProLink II, this value is called the Flowcal
parameter.
To obtain the required value:
For older T-Series sensors, concatenate the FCF value and the FT value from the sensor tag, as
shown below.
For newer T-Series sensors, the 10-character string is represented on the sensor tag as the FCF
value. The value should be entered exactly as shown, including the decimal points. No
concatenation is required.
For all other sensors, the 10-character string is represented on the sensor tag as the Flow Cal
value. The value should be entered exactly as shown, including the decimal points. No
concatenation is required.
4.2.3 How to characterize
To characterize the flowmeter:
1. See the menu flowchart in Figure 4-4.
2. Ensure that the correct sensor type is configured.

4.3 Configuring the channels
The six input/output terminals provided on the Model 1500 are organized into three pairs. These pairs
are called Channels A, B, and C. The channels should be configured before doing any other I/O
configuration.
The outputs and variable assignments are controlled by the channel configuration. Table 4-2 shows
how each channel may be configured and the power options for each channel.
.
To configure the channels, see the menu flowchart in Figure 4-5.
Figure 4-5 Configuring the channels
CAUTION
Changing the channel configuration without verifying I/O configuration can
produce process error.
When the configuration of a channel is changed, the channel’s behavior will be
controlled by the I/O configuration that is stored for the new channel type, which
may or may not be appropriate for the process. To avoid causing process error:
Configure the channels before configuring the I/O.
When changing channel configuration, be sure that all control loops affected by
this channel are under manual control.
Before returning the loop to automatic control, ensure that the channel's I/O is
correctly configured for your process. See Sections 4.5, 4.6, and 4.7.

Required Transmitter Configuration
4.5.1 Configuring the primary variable
The primary variable is the process variable to be reported through the mA output. Table 4-7 lists the
process variables that can be assigned to the mA outputs.
Note: The process variable assigned to the mA output is always the PV (primary variable).
4.5.2 Configuring the mA output range (LRV and URV)
The mA output uses a range of 4 to 20 mA to represent the assigned process variable. You must
specify:
The lower range value (LRV) – the value of the process variable that will be indicated when
the mA output produces 4 mA
The upper range value (URV) – the value of the process variable that will be indicated when
the mA output produces 20 mA
Enter values in the measurement units that are configured for the assigned process variable (see
Section 4.4).
Note: The URV can be set below the LRV; for example, the URV can be set to 0 and the LRV can be
set to 100.
4.5.3 Configuring the AO cutoff
The AO (analog output) cutoff specifies the lowest mass flow or volume flow value that will be
reported through the mA output. Any mass flow or volume flow values below the AO cutoff will be
reported as zero.
Note: For most applications, the default AO cutoff is used. Contact Micro Motion customer support
before changing the AO cutoff.
Multiple cutoffs
Cutoffs can also be configured for the mass flow and volume flow process variables (see Section 6.5).
If mass flow or volume flow has been assigned to the mA output, a non-zero value is configured for
the flow cutoff, and the AO cutoff is also configured, the cutoff occurs at the highest setting, as shown
in the following example.
Table 4-7 mA output process variable assignments
Process variable ProLink II label
Mass flow Mass Flow Rate
Volume flow Volume Flow Rate
Example Configuration:
mA output: Mass flow
AO cutoff: 10 g/sec
Mass flow cutoff: 15 g/sec
As a result, if the mass flow rate drops below 15 g/sec, the mA output
will report zero flow.

4.5.4 Configuring the fault action, fault value, and last measured value timeout
Note: If the mA output is configured for valve control, it cannot be used to report alarm status, and
the mA output will never go to fault levels.
If the transmitter encounters an internal fault condition, it can indicate the fault by sending a
preprogrammed output level to the receiving device. You can specify the output level by configuring
the fault action. Options are shown in Table 4-8.
By default, the transmitter immediately reports a fault when a fault is encountered. You can configure
the transmitter to delay reporting a fault by changing the last measured value timeout to a non-zero
value. During the fault timeout period, the transmitter continues to report its last valid measurement.
4.5.5 Configuring added damping
A damping value is a period of time, in seconds, over which the process variable value will change to
reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small,
rapid measurement fluctuations:
A high damping value makes the output appear to be smoother because the output must change
slowly.
A low damping value makes the output appear to be more erratic because the output changes
more quickly.
The added damping parameter specifies damping that will be applied to the mA output. It affects the
measurement of the process variable assigned to the mA output, but does not affect other outputs.
When you specify a new added damping value, it is automatically rounded down to the nearest valid
value. Note that added damping values are affected by the Update Rate parameter (see Section 6.7).
Note: Added damping is not applied if the mA output is fixed (i.e., during loop testing) or is reporting
a fault.

Fault action Fault output value
Upscale 21–24 mA (default: 22 mA)
Downscale 1.0–3.6 mA (default: 2.0 mA)
Internal zero The value associated with 0 (zero) flow, as determined by URV and LRV values
None(1)
(1) If the mA output fault action is set to None, the digital communications fault action should also be set to None. See
Section 6.12.1.
Tracks data for the assigned process variable; no fault action
CAUTION
Setting the fault action to NONE may result in process error due to
undetected fault conditions.
To avoid undetected fault conditions when the fault action is set to NONE, use
some other mechanism such as digital communications to monitor device status.
26 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Required Transmitter Configuration
Multiple damping parameters
Damping can also be configured for the mass flow and volume flow process variables (see
Section 6.6). If one of these process variables has been assigned to the mA output, a non-zero value is
configured for its damping, and added damping is also configured for the mA output, the effect of
damping the process variable is calculated first, and the added damping calculation is applied to the
result of that calculation. See the following example.
4.6 Configuring the discrete output(s)
Note: Configure the transmitter channels for the required output types before configuring individual
outputs. See Section 4.3.
The discrete outputs generate two voltage levels to represent ON or OFF states. The voltage levels
depend on the output’s polarity, as shown in Table 4-9. Figure 4-8 shows a diagram of a typical
discrete output circuit.
Example Configuration:
Flow damping: 1
mA output: Mass flow
Added damping: 2
As a result:
A change in mass flow will be reflected in the primary mA output
over a time period that is greater than 3 seconds. The exact time
period is calculated by the transmitter according to internal
algorithms which are not configurable.
CAUTION
Changing the channel configuration without verifying I/O configuration can
produce process error.
When the configuration of a channel is changed, the channel’s behavior will be
controlled by the configuration that is stored for the new channel type, which may or
may not be appropriate for the process. To avoid causing process error:
Configure the channels before configuring the discrete output (see Section 4.3).
When changing the discrete output configuration, be sure that all control loops
affected by this output are under manual control.
Before returning the loop to automatic control, ensure that the discrete output is
correctly configured for your process.

WARNING
Upon transmitter startup or abnormal power reset, any external device
controlled by a discrete output may be momentarily activated.
Upon transmitter startup or abnormal power reset, discrete output states are
unknown. As a result, an external device controlled by a discrete output may
receive current for a brief period.
When using Channel B as a discrete output:
You can prevent current flow upon normal startup by setting Channel B polarity
to active low.
There is no programmatic method to prevent current flow for Channel B upon
abnormal power reset. You must design the system so that a brief current flow to
the external device controlled by Channel B cannot cause negative
consequences.
When using Channel C as a discrete output, there is no programmatic method to
prevent current flow upon either transmitter startup or abnormal power reset. You
must design the system so that a brief current flow to the external device controlled
by Channel C cannot cause negative consequences.

4.7 Configuring the discrete input
Note: Configure the transmitter channels for the required input/output types before configuring the
discrete input. See Section 4.3.
The discrete input is used to initiate a transmitter action from a remote input device. If your
transmitter has been configured for a discrete input, the following actions may be assigned to the
discrete input:
•Begin fill
End fill
Pause fill
Resume fill
Reset fill total
Reset mass total
Reset volume total
Reset all totals
Note: If the filling and dosing application is active, the Reset All Totals function includes resetting the
fill total.
To configure the discrete input, see the menu flowchart in Figure 4-9.
4.8 Establishing a meter verification baseline
Note: This procedure applies only if your transmitter is connected to an enhanced core processor and
you have ordered the meter verification option. In addition, ProLink II v2.5 or later is required.
Meter verification is a method of establishing that the flowmeter is performing within factory
specifications. See Chapter 10 for more information about meter verification.
Micro Motion recommends performing meter verification several times over a range of process
conditions after the transmitter’s required configuration procedures have been completed. This will
establish a baseline for how widely the verification measurement varies under normal circumstances.
The range of process conditions should include expected temperature, pressure, density, and flow rate
variations.
CAUTION
Changing the channel configuration without verifying I/O configuration can
produce process error.
When the configuration of a channel is changed, the channel’s behavior will be
controlled by the configuration that is stored for the new channel type, which may or
may not be appropriate for the process. To avoid causing process error:
Configure the channels before configuring the discrete output (see Section 4.3).
When changing the discrete output configuration, be sure that all control loops
affected by this output are under manual control.
Before returning the loop to automatic control, ensure that the discrete output is
correctly configured for your process.

View the trend chart for these initial tests. By default, the specification uncertainty limit is set at
±4.0%, which will avoid false Fail/Caution results over the entire range of specified process
conditions. If you observe a structural integrity variation greater than 4% due to normal process
conditions, you may adjust the specification uncertainty limit to match your process variation. To
avoid false Fail/Caution results, it is advisable to set the specification uncertainty limit to
approximately twice the variation due to the effect of normal process conditions.
In order to perform this baseline analysis, you will need the enhanced meter verification capabilities

This chapter describes how to use the transmitter in everyday operation. The following topics and
procedures are discussed:
Recording process variables (see Section 5.2)
Viewing process variables (see Section 5.3)
Viewing transmitter status and alarms, and the alarm log (see Section 5.4)
Viewing and using the totalizers and inventories (see Section 5.5)
For information on using the filling and dosing application, see Chapter 8.
Note: All ProLink II procedures provided in this section assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 2 for more
information.
5.2 Recording process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low, and may help in fine-tuning transmitter configuration.
Record the following process variables:
Flow rate
• Density
•Temperature
Tube frequency
Pickoff voltage
•Drive gain
For information on using this information in troubleshooting, see Section 11.11.

2. If you have closed the Process Variables window:
a. Open the ProLink menu.
b. Select Process Variables.
5.4 Viewing transmitter status and alarms
You can view transmitter status using the status LED or ProLink II.
The transmitter broadcasts alarms whenever a process variable exceeds its defined limits or the
transmitter detects a fault condition. Using ProLink II, you can view active alarms and you can view
the alarm log. For information regarding all the possible alarms, see Table 11-4.

The alarm log is cleared and regenerated with every transmitter power cycle.
Note: The location of alarms in the Status or Alarm Log window is not affected by the configured
alarm severity (see Section 6.11.1). Alarms in the Status window are predefined as Critical,
Informational, or Operational. Alarms in the Alarm Log window are predefined as High Priority or
Low Priority.
5.5 Using the totalizers and inventories
The totalizers keep track of the total amount of mass or volume measured by the transmitter over a
period of time. The totalizers can be viewed, started, stopped, and reset.
The inventories track the same values as the totalizers but can be reset separately. Because the
inventories are reset separately, you can keep a running total of mass or volume across multiple
totalizer resets.
Note: Mass and volume totalizer and inventory values are held across transmitter power cycles. The
fill total is not held across power cycles.
Note: If the Special update rate is configured, no inventories are available. See Section 6.7.
To view the current value of the totalizers and inventories with ProLink II software:
1. Click ProLink.
2. Select Process Variables or Totalizer Control.
Table 5-2 shows how you can control the totalizers and inventories using ProLink II software. To get
to the Totalizer Control screen:
1. Click ProLink.
2. Select Totalizer Control.
Note: The fill total can be reset independently from the Run Filler window (see Section 8.3.1). It
cannot be reset independently from the Totalizer window.

6.4.1 About special measurement units
Special measurement units consist of:
Base unit – A combination of:
- Base mass or base volume unit – A measurement unit that the transmitter already
recognizes (e.g., kg, m3)
- Base time unit – A unit of time that the transmitter already recognizes (e.g., seconds, days)
Conversion factor – The number by which the base unit will be divided to convert to the
special unit
Special unit – A non-standard volume flow or mass flow unit of measure that you want to be
reported by the transmitter
The terms above are related by the following formula:
To create a special unit, you must:
1. Identify the simplest base volume or mass and base time units for your special mass flow or
volume flow unit. For example, to create the special volume flow unit pints per minute, the
simplest base units are gallons per minute:
Base volume unit: gallon
Base time unit: minute
2. Calculate the conversion factor using the formula below:
Note: 1 gallon per minute = 8 pints per minute
3. Name the new special mass flow or volume flow measurement unit and its corresponding
totalizer measurement unit:
Special volume flow measurement unit name: Pint/min
Volume totalizer measurement unit name: Pints
Names can be up to 8 characters long.
4. To apply the special measurement unit to mass flow or volume flow measurement, select
Special from the list of measurement units (see Section 4.4.1 or 4.4.2).
6.4.2 Special mass flow unit
To create a special mass flow measurement unit:
1. Specify the base mass unit.
2. Specify the base time unit.
3. Specify the mass flow conversion factor.
4. Assign a name to the new special mass flow measurement unit.
5. Assign a name to the mass totalizer measurement unit.

6.4.3 Special volume flow unit
To create a special volume flow measurement unit:
1. Specify the base volume unit.
2. Specify the base time unit.
3. Specify the volume flow conversion factor.
4. Assign a name to the new special volume flow measurement unit.
5. Assign a name to the volume totalizer measurement unit.
6.4.4 Special unit for gas
For many gas applications, standard or normal volume flow rate is used as the quasi mass flow rate.
Standard or normal volume flow rate is calculated as the mass flow rate divided by the density of the
gas at a reference condition.
To configure a mass flow special unit that represents standard or normal volume flow rate, you must
calculate the mass flow conversion factor from the density of the gas at a reference temperature,
pressure, and composition.
ProLink II offers a Gas Unit Configurator tool to calculate this mass flow conversion factor. The tool
will automatically update the mass flow conversion factor in the Special Units tab. If ProLink II is
not available, special mass units can be used to set up standard or normal volume flow units for gas
applications.
Note: Micro Motion recommends that you do not use the flowmeter to measure actual volume flow of
a gas (volumetric flow at line conditions). If you need to measure actual volume flow, contact Micro
Motion customer support.
To use the Gas Unit Configurator:
1. Start ProLink II and connect to your transmitter.
2. Open the Configuration window.
3. Click the Special Units tab.
4. Click the Gas Unit Configurator button.
5. Select the Time Unit that your special unit will be based on.
6. Click a radio button to specify that your special unit will be defined in terms of English Units
or SI (Système International) Units.
7. Click Next.
CAUTION
The flowmeter should not be used for measuring the actual volume of gases.
Standard or normal volume is the traditional unit for gas flow. Coriolis flowmeters
measure mass. Mass divided by standard or normal density yields standard or
normal volume units.

8. Define the standard density to be used in calculations.
To use a fixed standard density, click the top radio button, enter a value for standard
density in the Standard Density textbox, and click Next.
To use a calculated standard density, click the second radio button and click Next. Then
enter values for Reference Temperature, Reference Pressure, and Specific Gravity on
the next panel, and click Next.
9. Check the values displayed.
If they are appropriate for your application, click Finish. The special unit data will be
written to the transmitter.
If they are not appropriate for your application, click Back as many times as necessary to
return to the relevant panel, correct the problem, then repeat the above steps.
6.5 Configuring cutoffs
Cutoffs are user-defined values below which the transmitter reports a value of zero for the specified
process variable. Cutoffs can be set for mass flow, volume flow, or density.
See Table 6-1 for cutoff default values and related information. See Sections 6.5.1 and 6.5.2 for
information on how the cutoffs interact with other transmitter measurements.
6.5.1 Cutoffs and volume flow
The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow drops below
the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate will be calculated
from the actual mass flow process variable.
However, the density cutoff is applied to the volume flow calculation. Accordingly, if the density
drops below its configured cutoff value, both the reported density and the reported volume flow rate
will go to zero.
6.5.2 Interaction with the AO cutoff
The mA output also has a cutoff – the AO cutoff. If the mA output is configured for mass or volume
flow:
And the AO cutoff is set to a greater value than the mass and volume cutoffs, the flow
indicators will go to zero when the AO cutoff is reached.
And the AO cutoff is set to a lower value than the mass or volume cutoff, the flow indicator
will go to zero when the mass or volume cutoff is reached.
See Section 4.5.3 for more information on the AO cutoff.
Table 6-1 Cutoff default values
Cutoff type Default Comments
Mass flow 0.0 g/s Recommended setting: 0.5–1.0% of the sensor’s rated maximum flowrate

6.6 Configuring the damping values
A damping value is a period of time, in seconds, over which the process variable value will change to
reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small,
rapid measurement fluctuations.
A high damping value makes the output appear to be smoother because the output must change
slowly.
A low damping value makes the output appear to be more erratic because the output changes
more quickly.
When you specify a new damping value, it is automatically rounded down to the nearest valid
damping value. Flow, density, and temperature have different valid damping values. Valid damping
values are listed in Table 6-2.
For the Model 1500 transmitter with the filling and dosing application, the default damping value for
flow has been set to 0.04 seconds. For most filling and dosing applications, the default flow damping
value is used. Contact Micro Motion customer support before changing the flow damping value.
Before setting the damping values, review Sections 6.6.1 through 6.6.3 for information on how the
damping values interact with other transmitter measurements and parameters.
6.6.1 Damping and volume measurement
When configuring damping values, be aware that volume measurement is derived from mass and
density measurements; therefore, any damping applied to mass flow and density will affect volume
measurements. Be sure to set damping values accordingly.
6.6.2 Interaction with the added damping parameter
The mA output has a damping parameter – added damping. If damping is configured for flow, the mA
output is configured for mass flow or volume flow, and added damping is also configured for the mA
output, the effect of damping the process variable is calculated first, and the added damping
calculation is applied to the result of that calculation.
See Section 4.5.5 for more information on the added damping parameter.

40 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Optional Transmitter Configuration
6.6.3 Interaction with the update rate
Flow and density damping values depend on the configured Update Rate (see Section 6.7). If you
change the update rate, the damping values are automatically adjusted. Damping rates for Special are
20% of Normal damping rates. See Table 6-2.
Note: The specific process variable selected for the Special update rate is not relevant; all damping
values are adjusted as described.
6.7 Configuring the update rate
The update rate is the rate at which the sensor reports process variables to the transmitter. This affects
transmitter response time to changes in the process.
There are two settings for Update Rate: Normal and Special.
When Normal is configured, most process variables are polled at the rate of 20 times per
second (20 Hz).
When Special is configured, a single, user-specified process variable is reported at a faster
rate, and all others are reported at a slower rate. If you set the update rate to Special, you must
also specify which process variable will be updated at 100 Hz. Polling for some process
variables and diagnostic/calibration data is dropped (see Section 6.7.1), and the remaining
process variables are polled a minimum of 6 times per second (6.25 Hz).
Not all process variables can be used as the 100 Hz variable. Only the following process variables can
be selected:
Mass flow rate
Volume flow rate
For the Model 1500 transmitter with the filling and dosing application, Special is the default, and the
100 Hz variable is automatically set to the variable configured as the fill flow source (mass flow rate
or volume flow rate).
For filling and dosing applications, Micro Motion recommends:
•Use
Special for all “short” applications (fill duration less than 15 seconds).
•Use
Normal for all “long” applications (fill duration of 15 or more seconds).
For all other applications, Micro Motion recommends using the Normal update rate. Contact Micro
Motion before using the Special update rate for other applications.
Note: If you change the Update Rate setting, the setting for damping is automatically adjusted. See
Section 6.6.3.

6.7.1 Effects of Special mode
In Special mode:
Not all process variables are updated. The process variables listed below are always updated:
- Mass flow
-Volume flow
- Density
- Temperature
-Drive gain
- LPO amplitude
- RPO amplitude
- Status (contains Event 1 and Event 2)
- Raw tube frequency
- Mass total
- Volume total
-Board temperature
- Core input voltage
- Mass inventory
- Volume inventory
All other process variables are not polled at all. The omitted process variables will remain at
the values they held before Special mode was implemented.
Calibration data is not refreshed.
Micro Motion recommends the following:
If Special mode is required, ensure that all required data is being updated.
Do not perform any calibrations while in Special mode.
6.8 Configuring the flow direction parameter
Note: If the mA output is configured for valve control, this parameter has no effect.
The flow direction parameter controls how the transmitter reports flow rate and how flow is added to
or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.
Forward (positive) flow moves in the direction of the arrow on the sensor.
Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.

6.9 Configuring events
An event occurs if the real-time value of a user-specified process variable varies beyond a
user-specified value. Events are used to perform specific actions on the transmitter. For example, the
event can be defined to activate a discrete output if the flow rate is above a specified value. The
discrete output, then, may be configured to close a valve.
Note: Events cannot be used to manage the filling process.
You can define one or two events. You may define the events on a single process variable or on two
different process variables. Each event is associated with either a high or a low alarm.
Configuring an event includes the following steps:
1. Selecting Event 1 or Event 2.
2. Assigning a process variable to the event.
3. Specifying the Event Type:
Active High – alarm is triggered if process variable goes above setpoint
Active Low – alarm is triggered if process variable goes below setpoint

4. Specifying the setpoint – the value at which the event will occur or switch state (ON to OFF, or
vice versa).
Note: Events do not occur if the process variable equals the setpoint. The process variable must be
greater than (Active High) or less than (Active Low) the setpoint for the event to occur.
ProLink II automatically displays event information on the Informational panel of the Status window
and in the Output Levels window.
6.10 Configuring slug flow limits and duration
Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications.
The presence of slugs can significantly affect the process density reading. The slug flow parameters
can help the transmitter suppress extreme changes in process variables, and can also be used to
identify process conditions that require correction.
Slug flow parameters are as follows:
Low slug flow limit – the point below which a condition of slug flow will exist. Typically, this
is the lowest density point in your process’s normal density range. Default value is 0.0 g/cm3;
range is 0.0–10.0 g/cm3.
High slug flow limit – the point above which a condition of slug flow will exist. Typically, this
is the highest density point in your process’s normal density range. Default value is 5.0 g/cm3;
range is 0.0–10.0 g/cm3.
Slug flow duration – the number of seconds the transmitter waits for a slug flow condition
(outside the slug flow limits) to return to normal (inside the slug flow limits). If the transmitter
detects slug flow, it will post a slug flow alarm and hold its last “pre-slug flow” flow rate until
the end of the slug flow duration. If slugs are still present after the slug flow duration has
expired, the transmitter will report a flow rate of zero. Default value for slug flow duration is
0.0 seconds; range is 0.0–60.0 seconds.
Example Define Event 1 to indicate that the mass flow rate in forward or
backward direction is less than 2 lb/min.
1. Specify lb/min as the mass flow unit.
2. Set Flow Direction to Absolute Value.
3. Select Event 1.
4. Configure:
Variable = Mass Flow Rate
Type = Active Low
Setpoint = 2
Configuration and Use Manual 47
Optional Transmitter Configuration
Optional Configuration Using the FillerFiller ConfigurationUsing the Transmitter
If the transmitter detects slug flow:
A slug flow alarm is posted immediately.
During the slug duration period, the transmitter holds the mass flow rate at the last measured
pre-slug value, independent of the mass flow rate measured by the sensor. All outputs that
report mass flow rate and all internal calculations that include mass flow rate will use this
value.
If slugs are still present after the slug duration period expires, the transmitter forces the mass
flow rate to 0, independent of the mass flow rate measured by the sensor. All outputs that
report mass flow rate and all internal calculations that include mass flow rate will use 0.
When process density returns to a value within the slug flow limits, the slug flow alarm is
cleared and the mass flow rate reverts to the actual measured value.
Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility
that the transmitter will report slug flow.
Note: The slug flow limits must be entered in g/cm3, even if another unit has been configured for
density. Slug flow duration is entered in seconds.
Note: If slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is
detected.
6.11 Configuring fault handling
There are four ways that the transmitter can report faults:
By setting the mA output to its configured fault level (see Section 4.5.4 )
By configuring a discrete output to indicate fault status (see Section 4.6)
By setting the digital communications fault indicator (see Section 6.12.1)
By posting an alarm to the active alarm log
Status alarm severity controls which of these methods is used. For some faults only, fault timeout
controls when the fault is reported.
6.11.1 Changing status alarm severity
Status alarms are classified into three levels of severity. Severity level controls transmitter behavior
when the alarm condition occurs. See Table 6-4.
You cannot reclassify a Fault alarm, or change another alarm to a Fault alarm. However, alarms can
be reclassified from Informational to Ignore, or vice versa. For example, the default severity level for
the A118 – DO1 Fixed alarm is Information, but you can set it to Ignore.
Table 6-4 Alarm severity levels
Severity level Transmitter action
Fault If this condition occurs, an alarm will be generated and all outputs go to their
configured fault levels. Output configuration is described in Chapter 4.
Informational If this condition occurs, an alarm will be generated but output levels are not affected.
Ignore If this condition occurs, no alarm will be generated (no entry is added to the active
alarm log) and output levels are not affected.

6.11.2 Changing the fault timeout
By default, the transmitter immediately reports a fault when a fault is encountered. For specific faults,
you can configure the transmitter to delay reporting the fault by changing the fault timeout to a
non-zero value. If fault timeout is configured:
During the fault timeout period, the transmitter continues to report its last valid measurement.
The fault timeout applies only to the mA output and discrete output. Fault indication via digital
communications is unaffected.
The fault timeout is not applicable to all faults. See Table 6-5 for information about which faults are
affected by fault timeout.

transmitter will not be accessed using Modbus protocol, the Modbus address is not required.
Modbus addresses must be in the range 1–110, inclusive.

address, then:
If you are using ProLink II, ProLink II will automatically switch to the new address and retain
the connection.
If you are using a different host program, the connection will be broken. You must reconnect
using the new Modbus address.
Note: Changing the Modbus address does not affect service port connections. Service port
connections always use a default address of 111.
6.12.3 Changing the RS-485 parameters
RS-485 parameters control how the transmitter will communicate over its RS-485 terminals. The
following parameters can be set:
•Protocol
•Baud rate
• Parity
Stop bits
To enable RS-485 communications with the transmitter from a remote device:
1. Set the transmitter’s digital communications parameters appropriately for your network.
2. Configure the remote device to use the specified parameters.
If you are connected to the transmitter using an RS-485 connection:
And you change the the baud rate:
- If you are using ProLink II, ProLink II will automatically switch to the new baud rate and
retain the connection.
- If you are using a different host program, the connection will be broken. You must
reconnect using the new baud rate.
And you change the protocol, parity or stop bits, all host programs will lose the connection.
You must reconnect using the new settings.
Note: Changing the RS-485 communication settings does not affect service port connections. Service
port connections always use default settings.
Not-A-Number (NAN) Process variables report IEEE NAN and Modbus scaled integers report Max Int.
Totalizers stop counting.
Flow to Zero Flow rates go to the value that represents zero flow; other process variables are not
affected. Totalizers stop counting.
None (default) Process variables reported as measured.

6.12.4 Changing the floating-point byte order
Four bytes are used to transmit floating-point values. For contents of bytes, see Table 6-7.
The default byte order for the transmitter is 3–4–1–2. You may need to reset byte order to match the
byte order used by a remote host or PLC. Byte order codes are listed in Table 6-8.
6.12.5 Changing the additional communications response delay
Some hosts or PLCs operate at slower speeds than the transmitter. In order to synchronize
communication with these devices, you can configure an additional time delay to be added to each
response the transmitter sends to the remote host.
The basic unit of delay is in terms of 2/3 of one character time as calculated for the current serial port
baud rate setting and character transmission parameters. This basic delay unit is multiplied by the
configured value to arrive at the total additional time delay. You can specify a value in the range 1 to
255.
6.13 Configuring variable mapping
The Variable Mapping panel in the Configuration window provides another way to assign the primary
variable (PV). The PV parameter shown on this panel is the same as the Primary Variable parameter
in the Analog Output panel (see Section 4.5): if you change the parameter here, it is automatically
changed in the Analog Output panel, and vice versa.
The secondary variable (SV), tertiary variable (TV), and quaternary variable (QV) are not used by the
Model 1500 transmitter with the filling and dosing application, and cannot be changed.

7.1 About this chapter
This chapter explains how to configure the filling and dosing application on the Model 1500
transmitter. For information on using the filling and dosing application, see Chapter 8.
7.2 User interface requirements
ProLink II v2.3 or later is required to configure the filling and dosing application.
Alternatively, configuration can be performed via a customer-written program using the Modbus
interface to the Model 1500 transmitter and the filling and dosing application. Micro Motion has
published the Modbus interface in the following manuals:
Using Modbus Protocol with Micro Motion Transmitters, November 2004, P/N 3600219,
Rev. C (manual plus map)

Rev. B (map only)
Both of these manuals are available on the Micro Motion web site.
7.3 About the filling and dosing application
The filling and dosing application is used to begin flow, then end flow automatically when the target
amount of process fluid has flowed through the sensor. During a fill, flow may be paused and
resumed. A fill may also be ended before the target is reached.
CAUTION
Changing configuration can affect transmitter operation, including filling.
Changes made to filling configuration while a fill is running do not take effect until
the fill is ended. Changes made to other configuration parameters may affect filling.
To ensure correct filling, do not make any configuration changes while a fill is in
progress.
54 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Configuring the Filling and Dosing Application
Transmitter outputs change state according to fill status or operator commands. The control system
opens or closes valves in response to the signals from the transmitter. The filling and dosing
application must be configured for the type of valve used for fill control:
One-stage discrete – Fill controlled by a single discrete (ON/OFF) valve. The valve opens
completely when the fill begins, and closes completely when the fill target is reached (or the
fill is paused or ended).
Two-stage discrete – Fill controlled by two discrete valves: a primary valve and a secondary
valve. One valve must open at the beginning of the fill; the other opens at a user-defined point.
One valve must stay open until the end of the fill; the other closes at a user-defined point. See
Figure 7-1 for illustrations of the different opening and closing options.
Three-position analog – Fill controlled by one analog valve which can be fully open, fully
closed, or partially closed. See Figure 7-2 for an illustration of the three-position analog fill.
The Model 1500 filling transmitter provides three outputs which can be used for valve control:
Channel B always functions as a discrete output, and can be used to control the primary valve.
Channel C can function as a discrete output or a discrete input. When used as a discrete output,
it can be assigned to control the secondary valve.
The mA output on Channel A can function as:
- A discrete output, to control either the primary or secondary valve. When used as a
discrete output, an interposing solid-state relay is required.
- A three-level output, to control a three-position analog valve. When used as a three-level
output, the 20 mA output level sets the valve to open full, and two user-specified output
levels are used to set the valve to closed and to closed partial.
Note: If Channel A is configured for valve control, the channel cannot be used to report alarm status
and the mA output will never go to fault levels.
Accordingly:
A one-stage discrete fill requires either Channel A or Channel B configured to control the
primary valve.
A two-stage discrete fill requires any valid pair of Channels A, B, and C configured to control
the primary and secondary valves.
A three-position analog fill requires Channel A configured as a three-level output.
Note: See Table 7-1 for detailed information on output options.

Configuring the Filling and Dosing Application
7.3.1 Purge
Note: Two-stage discrete filling is not supported if a purge cycle is configured. If this functionality is
required, configure the mA output as a three-level output, to control the fill, and configure Channel C
as a discrete output, to control the purge.
If purge will be performed, one of the following valve control configurations is required:
Two discrete outputs (one may be the mA output configured as a discrete output). One must be
assigned to the primary valve and the other must be assigned to the secondary valve. The
primary valve is used to control the fill, and the secondary valve controls the purge.
The mA output configured as a three-level output, and Channel C configured as a discrete
output assigned to the secondary valve.
The second discrete output is typically set up to control compressed air or a vacuum. These
techniques are used to clear any process fluid that may be left in the piping from the previous fill.
There are two purge modes: manual and automatic.
If Manual is configured, the Begin Purge and End Purge buttons on the Run Filler window
are used to control the purge. The End Fill button also stops a purge.
If Auto is configured, the purge starts automatically after the configured Purge Delay, and
continues for the configured Purge Time. The purge may be stopped manually using the End
Fill button.
In both cases, the discrete output assigned to the secondary valve transmits an Open signal when the
purge begins, and transmits a Closed signal when the purge ends. The primary valve remains closed
throughout the purge.
The purge can be stopped at any point, by using the End Purge or End Fill button.
7.3.2 Cleaning
Cleaning does not require any special valve configuration. When cleaning is started, all valves
assigned to the system (except any valves configured for purging, as discussed in the previous section)
are opened; when cleaning is stopped, all valves assigned to the system are closed.
Typically, cleaning involves flowing water or air through the system.
7.4 Configuring the filling and dosing application
To configure the filling and dosing application:
1. Open the ProLink II Configuration window.
2. Click the Filling tab. The panel shown in Figure 7-3 is displayed. In this panel:

7.5 Overshoot compensation
Overshoot compensation keeps the actual quantity delivered as close as possible to the fill target by
compensating for the time required to close the valve. Without overshoot compensation, there will
always be some amount of overfill because of the time required for the transmitter to observe that the
target has been reached and send the command to close the valve, and then for the control system and
valve to respond. When overshoot compensation is configured, the transmitter issues the valve close
command before the target is reached. See Figure 7-6.

Figure 7-6 Overshoot compensation and flow
Three types of overshoot compensation can be configured:
Fixed – The valve will close at the point defined by the target minus the quantity specified in
Fixed Overshoot Comp.
Underfill – The valve will close at the point defined by the AOC coefficient calculated during
AOC calibration, adjusted to ensure that the actual quantity delivered never exceeds the target.
(The initial adjusted target is less than the actual target, and moves upward toward the target
during calibration.)
Overfill – The valve will close at the point defined by the AOC coefficient calculated during
AOC calibration, adjusted to ensure that the actual quantity delivered is never less than the
target. (The variance of the fills is added to the AOC-adjusted target.)
AOC calibration is required only if Underfill or Overfill is configured. There are two forms of AOC
calibration:
Standard – Several fills are run during a special “calibration period.” The AOC coefficient is
calculated from data collected from these fills. See Section 7.5.2 for instructions on the
standard AOC calibration procedure.
Rolling – The AOC coefficient is calculated from data collected from the x most recent fills,
where x is the value specified for AOC Window Length. There is no special calibration period.
For example, if AOC Window Length is set to 10, the first AOC coefficient is calculated from
the first ten fills. When the eleventh fill is run, the AOC coefficient is recalculated, based on
the ten most recent fills, and so on. No special calibration procedure is required.

Fixed overshoot compensation is used if the compensation value is already known. To configure fixed
overshoot compensation:
1. Disable the Enable AOC checkbox in the Filling panel (see Figure 7-3).
2. Set AOC Algorithm to Fixed.
3. Click Apply.
4. Specify the appropriate value for Fixed Overshoot Comp. Enter values in the unit used for
the flow source.
5. Click Apply.
Note: Do not enable the Enable AOC checkbox. The Enable AOC checkbox is enabled only for
underfill or overfill.
To configure automatic overshoot compensation for underfill or overfill:
1. Enable the Enable AOC checkbox in the Filling panel (see Figure 7-3).
2. Set AOC Algorithm to Underfill or Overfill.
3. Set AOC Window Length:
If standard AOC calibration will be used, specify the maximum number of fills that will be
used to calculate the AOC coefficient during calibration.
If rolling AOC calibration will be used, specify the number of fills that will be used to
calculate the AOC coefficient.
4. Click Apply.
5. If standard AOC calibration will be used, follow the instructions in Section 7.5.2. If rolling
AOC calibration will be used, follow the instructions in Section 7.5.3.
7.5.2 Standard AOC calibration
Note: In common use, the first training fill will always be slightly overfilled because the default
compensation factor is 0. To prevent this, set the AOC Coeff value in the Run Filler window (see
Figure 8-1) to a small positive number. This value must be small enough so that when it is multiplied
by the flow rate, the resulting value is less than the fill target.
To perform standard AOC calibration:
1. Click ProLink > Run Filler. The window shown in Figure 8-1 is displayed.
2. Click Start AOC Cal. The AOC Calibration Active light turns red, and will remain red while
AOC calibration is in progress.
3. Run as many fills as desired, up to the number specified in AOC Window Length.
Note: If you run more fills, the AOC coefficient is calculated from the x most recent fills, where x is the
value specified for AOC Window Length.
4. When the fill totals are consistently satisfactory, click Save AOC Cal.
The AOC coefficient is calculated from the fills run during this time period, and is displayed in the
Run Filler window. This factor will be applied to all subsequent fills while AOC is enabled, until
another AOC calibration is performed.

Optional Configuration Using the FillerFiller ConfigurationUsing the Transmitter
Another AOC calibration is recommended:
If equipment has been replaced or adjusted
If flow rate has changed significantly
If fills are consistently missing the target value
7.5.3 Rolling AOC calibration
Note: In common use, the first fill may be slightly overfilled because the default compensation factor
is 0.2. To prevent this, increase the AOC Coeff value in the Run Filler window (see Figure 8-1). This
value must be small enough so that when it is multiplied by the flow rate, the resulting value is less
than the fill target.
To enable rolling AOC calibration:
1. Click ProLink > Run Filler. The window shown in Figure 8-1 is displayed.
2. Click Start AOC Cal. The AOC Calibration Active light turns red.
3. Begin filling. Do not click Save AOC Cal. The AOC coefficient is recalculated after each fill,
and the current value is displayed in the Run Filler window.
At any time, you can click Save AOC Cal. The current AOC coefficient will be saved in the
transmitter and used for all overshoot compensation during subsequent fills. In other words, this
action changes the AOC calibration method from rolling to standard.

8.3.2 Using a discrete input
If a discrete input is assigned to a fill control function, the function is triggered when the discrete
input is in an ON state.
Table 8-3 lists the fill control functions. To assign a discrete input to trigger a fill function:
1. Ensure that Channel C is configured as a discrete input (see Section 4.3).
2. Open the ProLink II Configuration window and click on the Discrete IO tab. The panel
shown in Figure 8-2 is displayed.
3. Select the fill control function to be triggered. Fill control functions are listed and defined in
Table 8-3.

Purge In Progress A purge has been started, either automatically or manually.
Purge Delay Phase An automatic purge cycle is in progress, and is currently in the delay period between
the completion of the fill and the start of the purge.
Primary Valve The primary valve is open. If a three-position analog valve has been configured, the
valve is either open or closed partial.
Secondary Valve The secondary valve is open.
Start Not Okay One or more conditions required to start a fill are not met.
AOC Flow Rate Too High The last measured flow rate is too large to allow the fill to start. In other words, the AOC
coefficient, compensated for the flow rate, specifies that the valve close command
should be issued before the fill has begun. This can happen if the flow rate has
increased significantly with no corresponding change in the AOC coefficient. AOC
calibration is recommended. To adjust the AOC value, you can use the Override
Blocked Start function to run a fill without AOC (see Table 8-1).
AOC Calibration Active AOC calibration is in progress.

Chapter 9
Pressure Compensation
9.1 Overview
This chapter defines pressure compensation and describes how to configure it.
Note: All procedures provided in this chapter assume that your computer is already connected to the
transmitter and you have established communication. All procedures also assume that you are
complying with all applicable safety requirements. See Chapter 2 for more information.
9.2 Pressure compensation
The Model 1500 transmitter can compensate for the effect of pressure on the sensor flow tubes.
Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure
change away from calibration pressure.
Note: Pressure compensation is optional. Configure pressure compensation only if required by your
application.
9.2.1 Options
There are two ways to configure pressure compensation:
If the operating pressure is a known static value, you can enter the external pressure in the
software.
If the operating pressure varies significantly, you can use the transmitter’s Modbus interface to
write the current pressure value to the transmitter at appropriate intervals.
Note: If you configure a static pressure value, ensure that it is accurate. If you update the pressure via
Modbus, ensure that the external pressure measurement device is accurate and reliable.
9.2.2 Pressure correction factors
When configuring pressure compensation, you must provide the flow calibration pressure – the
pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there
will be no effect on the calibration factor). Refer to the calibration document shipped with your
sensor. If the data is unavailable, use 20 psi.
Two additional pressure correction factors may be configured: one for flow and one for density. These
are defined as follows:
Flow factor – the percent change in the flow rate per psi
Density factor – the change in fluid density, in g/cm3/psi
78 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Pressure Compensation
Not all sensors or applications require pressure correction factors. For the pressure correction values
to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse
the signs (e.g., if the pressure effect is 0.000004, enter a pressure correction factor of –0.000004).
9.2.3 Pressure measurement unit
The default measurement unit for pressure is PSI. In other words, the transmitter expects to receive
pressure data in psi. If you will use a different pressure measurement unit, you must configure the
transmitter to use that measurement unit.
See Table 9-1 for a complete list of pressure measurement units.

To enable and configure pressure compensation with ProLink II, see Figure 9-1.

Measurement Performance
10.1 Overview
This chapter describes the following procedures:
Meter verification (see Section 10.3)
Meter validation and adjusting meter factors (see Section 10.4)
Density calibration (see Section 10.5)
Temperature calibration (see Section 10.6)
Note: All procedures discussed in this chapter assume that you have established communication
between ProLink II and the Model 1500 transmitter and that you are complying with all applicable
safety requirements. See Chapter 2 for more information.
Note: For information on zero calibration, see Section 3.5. For information on AOC calibration, see
Chapter 7.
10.2 Meter validation, meter verification, and calibration
The Model 1500 transmitter supports the following procedures for the evaluation and adjustment of
measurement performance:
Meter verification – establishing confidence in the sensor’s performance by analyzing
secondary variables associated with flow and density
Meter validation – confirming performance by comparing the sensor’s measurements to a
primary standard
Calibration – establishing the relationship between a process variable (flow, density, or
temperature) and the signal produced by the sensor
To perform meter verification, your flowmeter must use the enhanced core processor and the meter
verification option must have been purchased.
These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before
performing any of these procedures, review these sections to ensure that you will be performing the
appropriate procedure for your purposes.
10.2.1 Meter verification
Meter verification evaluates the structural integrity of the sensor tubes by comparing current tube
stiffness to the stiffness measured at the factory. Stiffness is defined as the deflection of the tube per
unit of load, or force divided by displacement. Because a change in structural integrity changes the
sensor’s response to mass and density, this value can be used as an indicator of measurement
performance. Changes in tube stiffness are typically caused by erosion, corrosion, or tube damage.
Notes: To use meter verification, the transmitter must be paired with an enhanced core processor, and
the meter verification option must be purchased for the transmitter.
82 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Measurement Performance
Meter verification either holds the last output value or causes the outputs to go to the configured fault
values during the procedure (approximately 4 minutes).
Micro Motion recommends that you perform meter verification on a regular basis.
10.2.2 Meter validation and meter factors
Meter validation compares a measurement value reported by the transmitter with an external
measurement standard. Meter validation requires one data point.
Note: For meter validation to be useful, the external measurement standard must be more accurate
than the sensor. See the sensor’s product data sheet for its accuracy specification.
If the transmitter’s mass flow, volume flow, or density measurement is significantly different from the
external measurement standard, you may want to adjust the corresponding meter factor. A meter
factor is the value by which the transmitter multiplies the process variable value. The default meter
factors are 1.0, resulting in no difference between the data retrieved from the sensor and the data
reported externally.
Meter factors are typically used for proving the flowmeter against a weights and measures standard.
You may need to calculate and adjust meter factors periodically to comply with regulations.
10.2.3 Calibration
The flowmeter measures process variables based on fixed points of reference. Calibration adjusts
those points of reference. Three types of calibration can be performed:
Zero (see Section 3.5)
Density calibration
Temperature calibration
Density and temperature calibration require two data points (low and high) and an external
measurement for each. Calibration produces a change in the offset and/or the slope of the line that
represents the relationship between process density and the reported density value, or the relationship
between process temperature and the reported temperature value.
Note: For density or temperature calibration to be useful, the external measurements must be
accurate.
Flowmeters are calibrated at the factory, and normally do not need to be calibrated in the field.
Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact Micro
Motion before calibrating your flowmeter.
Micro Motion recommends using meter validation and meter factors, rather than calibration, to prove
the meter against a regulatory standard or to correct measurement error.
Configuration and Use Manual 83
Measurement Performance
Measurement Performance DefaultsTroubleshootingCompensation
10.2.4 Comparison and recommendations
When choosing among meter verification, meter validation, and calibration, consider the following
factors:
Process interruption
- Meter verification requires approximately four minutes to perform. During these four
minutes, flow can continue (provided sufficient stability is maintained); however, outputs
will not report process data.
- Meter validation for density does not interrupt the process at all. However, meter
validation for mass flow or volume flow requires process down-time for the length of the
test.
- Calibration requires process down-time. In addition, density and temperature calibration
require replacing the process fluid with low-density and high density fluids, or
low-temperature and high-temperature fluids.
External measurement requirements
- Meter verification does not require external measurements.
- Zero calibration does not require external measurements.
- Density calibration, temperature calibration, and meter validation require external
measurements. For good results, the external measurement must be highly accurate.
Measurement adjustment
- Meter verification is an indicator of sensor condition, but does not change flowmeter
internal measurement in any way.
- Meter validation does not change flowmeter internal measurement in any way. If you
decide to adjust a meter factor as a result of a meter validation procedure, only the reported
measurement is changed – the base measurement is not changed. You can always reverse
the change by returning the meter factor to its previous value.
- Calibration changes the transmitter’s interpretation of process data, and accordingly
changes the base measurement. If you perform a zero calibration, you can restore the
factory zero at a later time. You cannot return to the previous zero (if different from the
factory zero), density calibration values, or temperature calibration values unless you have
manually recorded them.
Micro Motion recommends obtaining the meter verification transmitter option and performing meter
verification on a regular basis.
10.3 Performing meter verification
Note: To use meter verification, the transmitter must be paired with an enhanced core processor, and
the meter verification option must be purchased for the transmitter.
The meter verification procedure can be performed on any process fluid. It is not necessary to match
factory conditions. Meter verification is not affected by any parameters configured for flow, density,
or temperature.
During the test, process conditions must be stable. To maximize stability:
Maintain a constant temperature and pressure.
Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).
Maintain a constant flow. For higher test certainty, reduce or stop flow.
84 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Measurement Performance
If stability varies outside test limits, the meter verification procedure will be aborted. Verify process
stability and retry.
During meter verification, you must choose to fix the outputs at either the configured fault levels or
the last measured value. The outputs will remain fixed for the duration of the test (approximately four
minutes). Disable all control loops for the duration of the procedure, and ensure that any data reported
during this period is handled appropriately.
To perform meter verification, follow the procedure illustrated in Figure 10-1. For a discussion of
meter verification results, see Section 10.2.1. For additional meter verification options provided by
ProLink II, see Section 10.3.2.

10.3.1 Specification uncertainty limit and test results
The result of the meter verification test will be a percent uncertainty of normalized tube stiffness. The
default limit for this uncertainty is ±4.0%. This limit is stored in the transmitter, and can be changed
with ProLink II when optional test parameters are entered. For most installations, it is advisable to
leave the uncertainty limit at the default value.
When the test is completed, the result will be reported as Pass, Fail, or Abort:
Pass – The test result is within the specification uncertainty limit. If transmitter zero and
configuration match factory values, the sensor will meet factory specifications for flow and
density measurement. It is expected that meters will pass meter verification every time the test
is run.
Fail/Caution – The test result is not within the specification uncertainty limit. Micro Motion
recommends that you immediately re-run the meter verification test. If the meter passes the
second test, the first Fail/Caution result can be ignored. If the meter fails the second test, the
flow tubes may be damaged. Use the knowledge of your process to consider the type of
damage and determine the appropriate action. These actions might include removing the meter
from service and physically inspecting the tubes. At minimum, you should perform a flow
validation (see Section 10.4) and a density calibration (see Section 10.5).
Abort – A problem occurred with the meter verification test (e.g., process instability). Check
your process and retry the test.

10.3.2 Additional ProLink II tools for meter verification
In addition to the Pass, Fail, and Abort result provided by the procedure, ProLink II provides the
following additional meter verification tools:
Test metadata – ProLink II allows you to enter a large amount of metadata about each test so
that past tests can be audited easily. ProLink II will prompt you for this optional data during
the test.
Visibility of configuration and zero changes – ProLink II has a pair of indicators that show
whether the transmitter’s configuration or zero has changed since the last meter verification
test. The indicators will be green if configuration and zero are the same, and red otherwise.
You can find out more information about changes to configuration and zero by clicking the
button next to each indicator.
Plotted data points – ProLink II shows the exact stiffness uncertainty on a graph. This allows
you to see not only whether the meter is operating within specification, but also where the
results fall within the specified limits. (The results are shown as two data points: LPO and
RPO. The trending of these two points can help identify if local or uniform changes are
occurring to the flow tubes.)
Trending – ProLink II has the ability to store a history of meter verification data points. This
history is displayed on the results graph. The rightmost data points are the most recent. This
history lets you see how your meter is trending over time, which can be an important way of
detecting meter problems before they become severe. You can view the graph of past results at
either the beginning or the end of the meter verification procedure. The graph is shown
automatically at the end. Click View Previous Test Data to view the graph at the beginning.
Data manipulation – You can manipulate the graphed data in various ways by double-clicking
the graph. When the graph configuration dialog is open, you can also export the graph in a
number of formats (including “to printer”) by clicking Export.
Detailed report form – At the end of a meter verification test, ProLink II displays a detailed
report of the test, which includes the same recommendations for pass/caution/abort results
found in Section 10.3.1. You have the options of printing the report or saving it to disk as an
HTML file.
More information about using ProLink II to perform meter verification can be found in the ProLink II
manual (ProLink II Software for Micro Motion Transmitters, P/N 20001909, Rev D or later) and in the
on-line ProLink II help system.
Note: Historical data (e.g., previous test results or whether zero has changed) are stored on the
computer on which ProLink II is installed. If you perform meter verification on the same transmitter
from a different computer, the historical data will not be visible.
10.4 Performing meter validation
To perform meter validation, measure a sample of the process fluid and compare the measurement
with the flowmeter’s reported value.
Use the following formula to calculate a meter factor:
Valid values for meter factors range from 0.8 to 1.2. If the calculated meter factor exceeds these
limits, contact Micro Motion customer service.

10.5 Performing density calibration
Density calibration includes the following calibration points:
All sensors:
- D1 calibration (low-density)
- D2 calibration (high-density)
T-Series sensors only:
- D3 calibration (optional)
- D4 calibration (optional)
For T-Series sensors, the optional D3 and D4 calibrations could improve the accuracy of the density
measurement. If you choose to perform the D3 and D4 calibration:
Do not perform the D1 or D2 calibration.
Perform D3 calibration if you have one calibrated fluid.
Perform both D3 and D4 calibrations if you have two calibrated fluids (other than air and
water).
The calibrations that you choose must be performed without interruption, in the order listed here.
Note: Before performing the calibration, record your current calibration parameters. If you are using
ProLink II, you can do this by saving the current configuration to a file on the PC. If the calibration
fails, restore the known values.
You can calibrate for density with ProLink II.
10.5.1 Preparing for density calibration
Before beginning density calibration, review the requirements in this section.
Sensor requirements
During density calibration, the sensor must be completely filled with the calibration fluid, and flow
through the sensor must be at the lowest rate allowed by your application. This is usually
accomplished by closing the shutoff valve downstream from the sensor, then filling the sensor with
the appropriate fluid.
Example The flowmeter is installed and proved for the first time. The flowmeter
mass measurement is 250.27 lb; the reference device measurement is
250 lb. A mass flow meter factor is determined as follows:
The first mass flow meter factor is 0.9989.
One year later, the flowmeter is proved again. The flowmeter mass
measurement is 250.07 lb; the reference device measurement is
250.25 lb. A new mass flow meter factor is determined as follows:
The new mass flow meter factor is 0.9996.

Density calibration fluids
D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You
may use air and water. If you are calibrating a T-Series sensor, the D1 fluid must be air and the D2
fluid must be water.
For D3 density calibration, the D3 fluid must meet the following requirements:
Minimum density of 0.6 g/cm3
Minimum difference of 0.1 g/cm3 between the density of the D3 fluid and the density of water.
The density of the D3 fluid may be either greater or less than the density of water
For D4 density calibration, the D4 fluid must meet the following requirements:
Minimum density of 0.6 g/cm3
Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the density of the
D3 fluid. The density of the D4 fluid must be greater than the density of the D3 fluid
Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the density of water.
The density of the D4 fluid may be either greater or less than the density of water
10.5.2 Density calibration procedures
To perform a D1 and D2 density calibration, see Figure 10-2.
To perform a D3 density calibration or a D3 and D4 density calibration, see Figure 10-3.
CAUTION
For T-Series sensors, the D1 calibration must be performed on air and the D2
calibration must be performed on water.

11.11 Checking process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low. The meter fingerprinting feature can also provide useful data (see Section 11.12).
Flow rate
• Density
•Temperature
Tube frequency
Pickoff voltage
•Drive gain
For troubleshooting, check the process variables under both normal flow and tubes-full no-flow
conditions. Except for flow rate, you should see little or no change between flow and no-flow
conditions. If you see a significant difference, record the values and contact Micro Motion customer
service for assistance. See Section 1.8.
Unusual values for process variables may indicate a variety of different problems. Table 11-5 lists
several possible problems and remedies.

11.12 Meter fingerprinting
The meter fingerprinting feature provides snapshots, or “fingerprints,” of twelve process variables, at
four different points of transmitter operation. See Table 11-6.
For all process variables except Mech Zero, the instantaneous value, 5-minute running average,
5-minute running standard deviation, recorded minimum, and recorded maximum are recorded. For
Mech Zero, only the 5-minute running average and 5-minute running standard deviation are recorded.
To use the meter fingerprinting feature:
1. From the ProLink menu, select Finger Print.
2. Use the Type pulldown list to specify the point in time for which you want to view data.
3. Use the Units pulldown list to specify SI or English units.
The display is updated continuously.
Note: Due to the continuous updating, the meter fingerprinting feature can have a negative effect on
other sensor-transmitter communications. Do not open the meter fingerprinting window unless you
plan to use it, and be sure to close it when you no longer need it.
11.13 Troubleshooting filling problems
If the fill cannot be started:
Check the status LED on the transmitter.
- If it is solid red, the transmitter is in a fault condition and a fill cannot be started. Correct
the fault condition and retry. The cleaning function may be useful.
- If it is solid yellow, the transmitter is in a low-severity fault condition, such as slug flow, or
the fill flow source, target, or discrete outputs are not correctly configured.
Note: A fill can be started under some low-severity fault conditions.
If the system is in slug flow, try using the cleaning function, or pulsing fluid through the
sensor by turning the discrete outputs ON and OFF (if the valves are controlled by discrete
outputs). The Test Discrete Output function can be used for this.
Ensure that the fill is correctly and completely configured:
- A flow source must be specified.
- A non-zero positive value must be specified for the fill target.
- All outputs required for valve control must be configured.

If standard AOC calibration is implemented, repeat the AOC calibration.
If rolling AOC calibration is implemented, try increasing the AOC Window Length value.
Check for mechanical problems with the valve.
11.14 Diagnosing wiring problems
Use the procedures in this section to check the transmitter installation for wiring problems.
11.14.1 Checking the power supply wiring
To check the power supply wiring:
1. Verify that the correct external fuse is used. An incorrect fuse can limit current to the
transmitter and keep it from initializing.
2. Power down the transmitter.
3. Ensure that the power supply wires are connected to the correct terminals. Refer to
Appendix B for diagrams.
4. Verify that the power supply wires are making good contact, and are not clamped to the wire
insulation.
5. Use a voltmeter to test the voltage at the transmitter’s power supply terminals. Verify that it is
within the specified limits. For DC power, you may need to size the cable. Refer to
Appendix B for diagrams, and see your transmitter installation manual for power supply
requirements.
11.14.2 Checking the sensor-to-transmitter wiring
To check the sensor-to-transmitter wiring, verify that:
The transmitter is connected to the sensor according to the wiring information provided in
your transmitter installation manual. Refer to Appendix B for diagrams.
The wires are making good contact with the terminals.
If the wires are incorrectly connected:
1. Power down the transmitter.
2. Correct the wiring.
3. Restore power to the transmitter.
11.14.3 Checking grounding
The sensor and the transmitter must be grounded. If the core processor is installed as part of the
sensor, it is grounded automatically. If the core processor is installed separately, it must be grounded
separately. See your sensor and transmitter installation manuals for grounding requirements and
instructions.

11.14.4 Checking for RF interference
If you are experiencing RF (radio frequency) interference on your discrete output, use one of the
following solutions:
Eliminate the RF source. Possible causes include a source of radio communications, or a large
transformer, pump, motor, or anything else that can generate a strong electrical or
electromagnetic field, in the vicinity of the transmitter.
Move the transmitter.
Use shielded cable for the discrete output.
- Terminate output cable shielding at the input device. If this is not possible, terminate the
output shielding at the cable gland or conduit fitting.
- Do not terminate shield inside the wiring compartment.
- 360° termination of shielding is not necessary.
11.15 Checking ProLink II
Ensure that you are using the required version of ProLink II. ProLink II v2.3 or later is required for
the Model 1500 transmitter with filling and dosing application. ProLink II v2.5 or later is required for
meter verification, and for some of the features and functions described in this manual.
To check the version of ProLink II:
1. Start ProLink II.
2. Open the Help menu.
3. Click About ProLink.
11.16 Checking the output wiring and receiving device
If you receive an inaccurate mA reading, there may be a problem with the output wiring or the
receiving device.
Check the output level at the transmitter.
Check the wiring between the transmitter and the receiving device.
Try a different receiving device.
11.17 Checking slug flow
Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications.
The presence of slugs can significantly affect the process density reading. Slug flow limits and
duration can help the transmitter suppress extreme changes in reading.
Note: Default slug flow limits are 0.0 and 5.0 g/cm3. Raising the low slug flow limit or lowering the
high slug flow limit will increase the possibility of slug flow conditions.
If slug limits have been configured, and slug flow occurs:
A slug flow alarm is generated.
All outputs that are configured to represent flow rate hold their last “pre-slug flow” value for
the configured slug flow duration.
104 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application
Troubleshooting
If the slug flow condition clears before the slug-flow duration expires:
Outputs that represent flow rate revert to reporting actual flow.
The slug flow alarm is deactivated, but remains in the active alarm log until it is
acknowledged.
If the slug flow condition does not clear before the slug-flow duration expires, outputs that represent
flow rate report a flow rate of zero.
If slug time is configured for 0.0 seconds, outputs that represent flow rate will report zero flow as
soon as slug flow is detected.
If slug flow occurs:
Check process for cavitation, flashing, or leaks.
Change the sensor orientation.
Monitor density.
If desired, enter new slug flow limits (see Section 6.10).
If desired, increase slug duration (see Section 6.10).
11.18 Checking output saturation
If an output variable exceeds the upper range limit or goes below the lower range limit, the
applications platform produces an output saturation alarm. The alarm can mean:
The output variable is outside appropriate limits for the process.
The unit of flow needs to be changed.
Sensor flow tubes are not filled with process fluid.
Sensor flow tubes are plugged.
If an output saturation alarm occurs:
Bring flow rate within sensor limit.
Check the measurement unit. You may be able to use a smaller or larger unit.
Check the sensor:
- Ensure that flow tubes are full.
- Purge flow tubes.
For the mA outputs, change the mA URV and LRV (see Section 4.5.2).
11.19 Checking the flow measurement unit
Using an incorrect flow measurement unit can cause the transmitter to produce unexpected output
levels, with unpredictable effects on the process. Make sure that the configured flow measurement
unit is correct. Check the abbreviations; for example, g/min represents grams per minute, not gallons
per minute. See Section 4.4.
11.20 Checking the upper and lower range values
A saturated mA output or incorrect mA measurement could indicate a faulty URV or LRV. Verify that
the URV and LRV are correct and change them if necessary. See Section 4.5.2.
