Power Module Considerations
Each Power Module contains two "C" size primary lithium/thionyl chloride batteries. Each
battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack.
Under normal conditions, the battery materials are self-contained and are not reactive as
long as the batteries and the pack integrity are maintained. Care should be taken to prevent
thermal, electrical or mechanical damage. Contacts should be protected to prevent
premature discharge.
Battery hazards remain when cells are discharged.
Power modules should be stored in a clean and dry area. For maximum battery life, storage
temperature should not exceed 30° C.
The Power Module may be replaced in a hazardous area. The Power Module has surface
resistivity greater than one gigaohm and must be properly installed in the wireless device
enclosure. Care must be taken during transportation to and from the point of installation to
prevent electrostatic charge build-up.
NOTICE
Shipping considerations for wireless products
The unit was shipped to you without the Power Module installed. Please remove the Power
Module prior to shipping the unit.
Each Power Module contains two "C" size primary lithium/thionyl chloride batteries. Primary
lithium batteries are regulated in transportation by the U.S. Department of Transportation,
and are also covered by IATA (International Air Transport Association), ICAO (International
Civil Aviation Organization), and ARD (European Ground Transportation of Dangerous
Goods). It is the responsibility of the shipper to ensure compliance with these or any other
local requirements. Please consult current regulations and requirements before shipping

THEORY OF OPERATION
PRELIMINARY
Rosemount 3308
The Rosemount 3308 Wireless Guided Wave Radar Level Transmitter is a
continuous level transmitter that is based on Time Domain Reflectometry
(TDR) principles. Low power nano-second-pulses are guided along a probe
immersed in the process media. When a pulse reaches the surface of the
material it is measuring, part of the energy is reflected back to the transmitter,
and the time difference between the generated and reflected pulse is
converted into a distance from which the total level or interface level is
calculated (see below).
The reflectivity of the product is a key parameter for measurement
performance. A high dielectric constant of the media gives better reflection
and a longer measuring range. A calm surface gives better reflection than a
turbulent surface.

APPLICATION
EXAMPLES
The Rosemount 3308 transmitter is suited for aggregate (total) level
measurements on most liquids, semi-liquids, and liquid/liquid interfaces.
Guided microwave technology offers highest reliability and precision which
ensure measurements are virtually unaffected by temperature, pressure,
vapor gas mixtures, density, turbulence, bubbling/boiling, low level, varying
dielectric media, pH, and viscosity.
Guided wave radar technology in combination with advanced signal
processing make the Rosemount 3308 transmitter suitable for a wide range of
applications.

Underground tanks
The Rosemount 3308 transmitter is a good choice for
underground tanks since it is installed on the tank top
with the radar pulse concentrated near the probe. It can
be equipped with probes that are unaffected by high and
narrow openings or nearby objects.
Small ammonia, NGL and LPG tanks
Guided wave radar technology is a good choice for
reliable measurements in small ammonia, NGL and LPG
tanks.

SYSTEM
ARCHITECTURE
Reference Manual
00809-XXXX-4811, Rev AA
February 2012
The Rosemount 3308 transmitter is battery powered with wireless
communication which means the unit works completely independent.
By using the optional HART Tri-loop, it is possible to convert the HART signal
to up to three additional 4-20 mA analog signals.
With the HART protocol it is possible to use multidrop configuration. In this
case communication is restricted to digital since current is fixed to the 4 mA
minimum value.
The transmitter can be connected to display Rosemount 751 Field Signal
Indicator or it can be equipped with an integral display.
The transmitter can easily be configured by using the AMS suite software or
by using a Field Communicator. A PC with the Radar Configuration Tool
software can also be used for configuration.
For HART communication a minimum load resistance of 250  within the loop
is required.

Interface
PRELIMINARY
Rosemount 3308
Rosemount 3308 is the ideal choice for measuring the interface of oil and
water, or other liquids with significant dielectric differences.
Figure 2-3. Interface
measurement with a
Rosemount 3308
Level
Interface Level
Level = Interface Level
All probes can be used for measuring interfaces. The coaxial probe is the
preferred choice for clean liquids and when the bridle is not fully immersed. In
applications with a fully immersed probe, the twin lead probes are
recommended for nozzle installations, and the rigid single lead probe is best
for bridle mounting.
For measuring the interface level, the transmitter uses the residual wave of
the first reflection. Part of the wave, which was not reflected at the upper
product surface, continues until it is reflected at the lower product surface.
The speed of this wave depends fully on the dielectric constant of the upper
product.
If interface is to be measured, the following criteria have to be fulfilled:
•
The dielectric constant of the upper product must be known. The Radar
Configuration Tools software has a built-in dielectric constant calculator
to assist users in determining the dielectric constant of the upper
product.
•
The dielectric constant of the upper product must have a lower
dielectric constant than the lower product in order to have a distinct
reflection.
•
The difference between the dielectric constants for the two products
must be larger than 10.
•
Maximum dielectric constant for the upper product is 10 for the coaxial
probe and 5 for twin lead probes.
•
The upper product thickness must be larger than 8 inches (0.2 m) for
the flexible twin lead probe and 4 inches (0.1 m) for the rigid twin lead
and coaxial probes in order to distinguish the echoes of the two liquids.
The maximum allowable upper product thickness/measuring range is
primarily determined by the dielectric constants of the two liquids.
Target applications include interfaces between oil/oil-like and water/water-like
liquids. For such applications the upper product dielectric constant is low (<3)
and the lower product dielectric constant is high (>20), and the maximum
measuring range is only limited by the length of the coaxial and rigid twin lead
probes.

Emulsion Layers
Sometimes there is an emulsion layer (mix of the products) between the two
products which, depending on its characteristics, will affect interface
measurements.
Please consult factory for guidelines on how to handle emulsion layers.

Rosemount 3308
VESSEL
CHARACTERISTICS
Heating Coils, Agitators
The Rosemount 3308 transmitter is relatively insensitive to objects in the tank
since the radar signal is transmitted along a probe.
Avoid physical contact between probes and agitators as well as applications
with strong fluid movement unless the probe is anchored. If the probe can
move within 1 ft (30 cm) away from any object, such as an agitator, during
operation then probe tie-down is recommended.
In order to stabilize the probe for side forces, it is possible to hang a weight at
the probe end (flexible probes only) or fix/guide the probe to the tank bottom.
Tank Shape
The guided wave radar transmitter is insensitive to the tank shape. Since the
radar signal travels along a probe, the shape of the tank bottom has virtually
no effect on the measurement performance. The transmitter handles flat or
dish-bottom tanks equally well.

Transition Zones
The measuring range depends on probe type and properties of the product.
The Upper Transition Zone is the minimum measurement distance between
the upper reference point and the product surface. The Upper Transition Zone
varies between 4 - 20 in. (0.1 and 0.5 m) depending on probe type and
product.
At the end of the probe the measuring range is reduced by the Lower
Transition Zone. The Lower Transition Zone also varies depending on
probe type and product.

WIRELESS
CONSIDERATIONS
General
The Wireless Guided Wave Radar Transmitter has the capability to measure
level, distance, interface level or volume. The Rosemount 3308 converts the
measurement data into mapped variables and diagnostic information that are
transmitted through a wireless signal.
Power Up Sequence
The Smart Wireless Gateway (Gateway) should be installed and functioning
properly before any wireless field devices are powered. Install the Black
Power Module, SmartPower™ Solutions model number 701PBKKF into the
3308 transmitter to power the device. Wireless devices should also be
powered up in order of proximity from the Gateway, beginning with the
closest. This will result in a simpler and faster network installation. Enable
Active Advertising on the Gateway to ensure that new devices join the
network faster. For more information, see the Gateway Product Manual
(Document Number 00809-0200-4420).
Antenna Position
The antenna should be positioned vertically, either straight up or straight
down. It should be approximately 3 ft (1 m) from any large structure, building,
or conductive surface to allow for clear communication to other devices.

Electrical shock can result in death or serious injury:
•
Avoid contact with the leads and terminals. High voltage that may be present on
leads can cause electrical shock.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable level
of electrostatic charge under certain extreme conditions. Therefore, when the probe is used
in a potentially explosive atmosphere, appropriate measures must be taken to prevent
electrostatic discharge.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following

Zone adjustment
The transmitter can be mounted in nozzles by using an appropriate flange. It
is recommended that the nozzle size is within the dimensions given in
Table 4-1. For small nozzles it may be necessary to increase the Upper Null
Zone (UNZ) in order to reduce the measuring range in the upper part of the
tank. By setting the UNZ equal to the nozzle height, the impact on the
measurement due to interfering echoes from the nozzle will be reduced to a
minimum. See also section “Disturbances at the Top of the Tank“ on
page 7-10. Amplitude Threshold adjustments may also be needed in this
case.

PARAMETERS
The Rosemount 3308 transmitter can be configured for level, volume,

The Rosemount 3308 transmitter can be pre-configured according to the
ordering specifications in the Configuration Data Sheet.
Basic Configuration
The basic transmitter configuration includes setting the tank geometry
parameters. For interface measurements the dielectric constant of the top
liquid must also be given. For some applications with heavy vapor, the vapor
dielectric must be given as well.

Tank Height
The Tank Height is the distance from the Upper Reference Point to the bottom
of the tank. The transmitter measures the distance to the product surface and
subtracts this value from the Tank Height to determine the level.
Probe Length
The probe length is the distance between the Upper Reference Point and the
end of the probe. If a weight is used at the end of the probe it shall not be
included.
This parameter is pre-configured at factory. It must be changed if the probe is
shortened.
Probe Type
The transmitter is designed to optimize measurement performance for each
probe type.
This parameter is pre-configured at factory. This value needs to be changed if
the probe type is changed.
Dielectric Constant of Upper Product
For interface measurements the dielectric constant of the upper product is
essential in order to obtain good accuracy. See section “Interface” on
page 2-7 for further information on dielectric constants.
If the dielectric constant of the lower product is significantly smaller than the
dielectric constant of water, you may need to make special adjustments. See
section “Interface Measurements for Semi-Transparent Bottom Products” on
page 7-5 for further information.
For level measurements the Upper Product Dielectric parameter corresponds
to the actual dielectric constant of the product in the tank. Normally this
parameter does not need to be changed even if the actual dielectric constant
of the product deviates from the Upper Product Dielectric parameter value.
However, for some products measurement performance can be optimized by
setting the proper product dielectric constant.
Dielectric Constant of Vapor
In some applications there is heavy vapor above the product surface having a
significant influence on the level measurement. In such cases the vapor
dielectric can be entered to compensate for this effect.
The default value is equal to 1 which corresponds to the dielectricity of
vacuum. Normally this value does not need to be changed since the effect on
measurement performance is very small for most vapors.

Use a strapping table if a standard tank type does not provide sufficient
accuracy. Use most of the strapping points in regions where the tank shape is
non-linear. A maximum of 10 points can be added to the strapping table.
Figure 5-5. Strapping points
Actual tank bottom may look like this.
Using only 3 strapping points results in a level-to-volume profile
that is more angular than the actual shape.
Using 6 of the points at the bottom of the tank yields a
level-to-volume profile that is similar to the actual tank bottom.

BASIC CONFIGURATION
PRELIMINARY
Rosemount 3308
This section describes the various HART commands used to configure the
Rosemount 3308 transmitter for level measurements. The transmitter outputs
a digital HART wireless signal.
Transmitter Variables
HART Comm
TO BE
ADDED
You may assign up to four transmitter variables. Typically, the primary variable
(PV) is configured to be Aggregate Level, Interface Level or Volume.
Measurement Units
HART Comm
TO BE
ADDED
Set transmitter units for level and temperature.
TO BE
ADDED
The Tank Height is the distance from the Upper Reference Point to the bottom
of the tank (see Figure 5-3 on page 5-3). When setting the Tank Height, keep
in mind that this value is used for all level measurements performed by the
Rosemount 3308 transmitter.
Tank Height
HART Comm
The Tank Height must be set in linear (level) units, such as feet or meters,
regardless of primary variable assignment.
Probe Length
HART Comm
TO BE
ADDED
The probe length is the distance from the Upper Reference Point to the end of
the probe, see Figure 5-3. If the probe is anchored to a weight do not include
the height of the weight. This parameter is pre-configured at factory. The
Probe Length needs to be changed if, for example, the probe is shortened.

Rosemount 3308
Reference Manual
00809-XXXX-4811, Rev AA

Probe Type
HART Comm
TO BE
ADDED
The transmitter automatically makes an initial calibration based on the type of
probe that is used. This parameter is pre-configured at factory and only needs
to be set if the probe is changed to another type. Choose one of the following
options:
•
Flexible Twin
•
Coaxial
•
Rigid Single, Rigid Single PTFE
•
Flexible Single, Flexible Single PTFE
Product Dielectric
HART Comm
TO BE
ADDED
For interface measurements the dielectric constant of the upper product is
essential for calculating the interface level and the upper product thickness.
By default the Product Dielectric parameter is about 2.
If the dielectric constant of the lower product is significantly smaller than the
dielectric constant of water, you may need to make special adjustments. See
section “Interface Measurements for Semi-Transparent Bottom Products” on
page 7-5 for further information.The dielectric constant of the product is used
for setting the appropriate signal amplitude thresholds, see Section 7: Service
and Troubleshooting for more information on amplitude threshold settings.
Normally this parameter does not need to be changed for level
measurements. However, for some products measurement performance can
be optimized by setting the proper product dielectric constant.
The AMS Suite software includes a Dielectric Chart which lists the dielectric
constants of a wide range of products. AMS also includes a tool which allows
you to calculate dielectric constants based on measurements of the Upper
Product Thickness.
Vapor Dielectric
HART Comm
TO BE
ADDED
In some applications there is heavy vapor above the product surface having a
significant influence on the level measurement. In such cases the vapor
dielectric can be entered to compensate for this effect.
The default value is equal to 1 which corresponds to the dielectric constant of
vacuum. Normally this value does not need to be changed since the effect on
measurement performance is very small for most vapors.

Measurement Mode
HART Comm
TO BE
ADDED
Normally the Measurement Mode does not need to be changed. The
transmitter is pre-configured according to the specified model:
Table 5-2. Measurement Mode
Model
Measurement Mode
3308
Level, Level and Interface(1), Interface Immersed probe
(1) Default setting
Interface Immersed Probe is used for applications where the probe is fully
immersed in liquid. In this mode the transmitter ignores the upper product
level. See Section 7: Interface Measurements with Fully Immersed Probes for
more information.
NOTE!
Only use Interface Immersed Probe for applications where interface is
measured for a fully immersed probe.
Probe Angle
HART Comm
TO BE
ADDED
Maximum Upper Product
Thickness
HART Comm
TO BE
ADDED
Enter the angle between the probe and the vertical line. The default value is
equal to zero. Do not change this value if the transmitter is mounted with the
probe along the vertical line (which is normally the case).
For interface measurements the Maximum Upper Product Thickness
parameter may be used in special cases when the dielectric constant of the
upper product is relatively high. By setting this parameter you can avoid that
interface measurements are getting out of range.

REPLACEMENT
Reference Manual
00809-XXXX-4811, Rev AA
February 2012
Expected Power Module life is XX years at reference conditions(1).
Add warnings
When the Power Module needs to be replaced, remove the Power Module
cover and the depleted Power Module. Replace the power module with a new
Black Power Module, SmartPower™ Solutions model number 701PBKKF.
Replace the cover and ensure that the power module cover is fully tightened
to prevent moisture ingress. The lip of the power module cover should be in
contact with the metal enclosure to ensure a proper seal. Do not over tighten.
Handling Considerations
The Black Power Module with the wireless unit contains two "C" size primary
lithium/thionyl chloride batteries. Each battery contains approximately 2.5
grams of lithium, for a total of 5 grams in each Power Module. Under normal
conditions, the battery materials are self-contained and are not reactive as
long as the batteries and the battery pack integrity are maintained. Care
should be taken to prevent thermal, electrical or mechanical damage.
Contacts should be protected to prevent premature discharge.
Use caution when handling the power module, it may be damaged if dropped
from heights in excess of 20 ft (6 m).
Battery hazards remain when cells are discharged.
Environmental Considerations
As with any battery, local environmental rules and regulations should be
consulted for proper management of spent batteries. If no specific
requirements exist, recycling through a qualified recycler is encouraged.
Consult the materials safety data sheet for battery specific information.
Shipping Considerations
The unit was shipped to you without the power module installed. Please
remove the power module prior to shipping.
Each Black Power Module contains two "C" size primary lithium batteries.
Primary lithium batteries are regulated in transportation by the U.S.
Department of Transportation, and are also covered by International Air
Transport Association (IATA), International Civil Aviation Organization (ICAO),
and European Ground Transportation of Dangerous Goods (ARD). It is the
responsibility of the shipper to ensure compliance with these or any other
local requirements. Please consult current regulations and requirements
before shipping.

Procedures and instructions in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Explosions could result in death or serious injury.
Verify that the operating environment of the gauge is consistent with the appropriate
hazardous locations certifications.
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an Explosion-proof/Flameproof installation, do not remove the transmitter cover when
power is applied to the unit.
Failure to follow safe installation and servicing guidelines could result in death or
serious injury.
Make sure only qualified personnel perform the installation.
Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
Do not perform any service other than those contained in this manual unless you are
qualified.
High voltage that may be present on leads could cause electrical shock.
Avoid contact with leads and terminals.
Make sure the main power to the Rosemount 3308 transmitter is off and the lines to any
other external power source are disconnected or not powered while wiring
the gauge.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable
level of electrostatic charge under certain extreme conditions. Therefore, when the
probe is used in a potentially explosive atmosphere, appropriate measures must be
taken to prevent electrostatic discharge.
Process leaks could result in death or serious injury.
Make sure that the transmitter is handled carefully. If the Process Seal is damaged, gas
might escape from the tank if the transmitter head is removed from the probe.

Plotting the
Measurement Signal
The Radar Configuration Tool (RCT) has powerful tools for advanced
troubleshooting. By using the Waveform Plot function you get an instant view
of the tank signal. Measurement problems can be solved by studying the
position and amplitude of the different pulses.
To plot the measurement signal:
1. Start the Radar Configuration Tool program.
2. Choose the View>Plotting menu option, or choose the Plotting icon in
the RCT workspace (Advanced page at the left side of the workspace)
and click the Read
button.
Figure 7-2. Waveform plot in RCT
Upper Null Zone
In a typical measurement situation the following pulses appear in the diagram:
P1 - Reference pulse. This pulse is caused by the transition between
transmitter head and probe. It is used by the transmitter as a reference at
level measurements.
P2 - Product surface. This pulse is caused by a reflection on the product
surface. In Measurement Mode=Interface when Immersed Probe however, P2
indicates the interface since the surface of the upper product is ignored.
P3 - Interface or probe end. This pulse is caused by reflection on the interface
between an upper product and a bottom product with a relatively high
dielectric constant. It may also be caused by the probe end if there is no
product above. This pulse is shown when the transmitter is in Measurement
Mode=Level & Interface.
Different amplitude thresholds are used in order to filter out unwanted signals.
The following amplitude thresholds are used for the Rosemount 3308
transmitter:
T1 - amplitude threshold for detection of the Reference pulse P1.

Interface Measurements
for Semi-Transparent
Bottom Products
PRELIMINARY
Rosemount 3308
In interface applications where the bottom product has a low dielectric
constant, or if the signal is attenuated in the upper product, the amplitude of
the reflected signal is relatively low and difficult for the transmitter to detect. In
such a case it may be possible to detect the reflected signal if the
corresponding amplitude threshold is adjusted.
The Radar Configuration Tool (RCT) lets you view a waveform plot to analyze
the measurement signal. The plot shows the signal and the thresholds used
for the different amplitude peaks. By adjusting amplitude threshold T3 it is
possible to detect even weak interface signals.
Guidelines for amplitude threshold settings:
•
The amplitude threshold T3 should be approximately 50 % of the
interface signal amplitude.
•
Threshold T3 should not be less than 3.
•
If possible, T3 should be higher than T2.
You can use the RCT software or a Field Communicator to change the
amplitude thresholds. For the Field Communicator use the HART command
[1, 4, 5, 3]. See also “Amplitude Threshold Settings” on page 7-12.
RCT lets you view a plot of the measurement signal along with the current
thresholds:
1. From the View menu choose the Plotting option, or double-click the
Plotting icon in the Advanced section of the RCT Project Bar.
2. Click the Read button
3. To adjust the Amplitude Thresholds open the Advanced section in the

High Level Rates
PRELIMINARY
Rosemount 3308
The measurement signal is filtered in order to minimize the influence of
disturbing noise. In most measurement situations this does not have a
noticeable effect on the response time to level changes. If high level rates
occur it may however be necessary to reduce the damping value in order to
allow the transmitter to respond quicker. If there is too much noise the
damping value may be increased in order to get a stable measurement signal.
You can use the RCT software or a Field Communicator to change the
Damping value. For the HART Communicator use the key sequence
[1, 3, 5].
In the RCT software open the Setup>Output tab and enter the desired
Damping value:
Output tab
Damping
The Damping parameter determines how quickly the transmitter responds to
level changes and how robust the measurement signal is against noise.
Technically, a damping value of 10 means that in 10 seconds the output from
the transmitter is about 63% of the new level value. Consequently, when there
are rapid level changes in the tank, it may be necessary to decrease the
Damping value for the transmitter to be able to track the surface. On the other
hand, in noisy environments, and if level rates are low, it may be better to
increase the damping value to have a stable output signal.

Interface Measurements

Reference Manual
00809-XXXX-4811, Rev AA
February 2012
The Rosemount 3308 transmitter has a measurement option which makes it
possible to handle interface measurements when the product level is not
visible, for example in a full bridle pipe as illustrated in Figure 7-6. In this case
the probe is fully immersed into the upper product, and only the interface level
is detected by the transmitter. Even if the upper product level drops, it is
ignored by the transmitter which continues to measure only the interface level,
but the measurement accuracy is reduced since the transmitter does not take
into account the influence of the air gap above the product surface.
The Measurement Mode parameter is available via the
HART command [1, 3, 3, 4]. Choose the Interface when Immersed Probe
option.
Measurement mode Interface when Immersed Probe can also be activated in
the RCT software:
1. Open the Setup window.
2. Select the Tank Config tab.
3. Choose Measurement Mode Interface when Immersed Probe.
4. Click the Send Page button.
NOTE!
Do not use Measurement Mode Interface when Immersed Probe in “standard”
applications when both Interface Level and Product Level are measured.
If the product level drops, the air filled region in the upper part of the pipe will
slightly reduce the measurement accuracy of the interface level. To achieve
high accuracy in this measurement mode the probe must be fully immersed.

Level and Distance
Calibration
When calibrating the transmitter it is important that the product surface is calm
and that the tank is not being filled or emptied.
A complete calibration is performed in two steps:
1. Calibrate the Distance measurement by adjusting the Calibration Offset
parameter.
2. Calibrate the Level measurement by adjusting the Tank Height.
Distance calibration
1. Measure the actual distance between the Upper Reference Point and the
product surface.
2. Adjust the Calibration Offset so that the Distance measured by the
transmitter corresponds to the actual distance.
The Calibration Offset parameter is available via
HART command [1, 4, 5, 5],
or

Using the Trim Near Zone Function
For transmitters using the Guided Wave Radar technology the performance In
the Near Zone (referred to as the region between 0-1.6 ft (0-0.5 m) below the
Upper Reference Point) is normally somewhat limited. However, the
Rosemount 3308 transmitter is equipped with software functionality that
minimizes the Upper Transition Zone. The factory setting is normally sufficient
and doesn’t need to be repeated after installation.
However, since the setting is optimized depending on actual installation,
further trimming may be necessary in the case of unfavorable conditions. This
may for example be the case if a Single Lead probe is mounted in a small
nozzle, or if there are disturbing obstacles in the Near Zone. The trimming
means that the measurement performance in the Near Zone is maintained
even under these conditions and prevents false echo indication.
To trim the Near Zone performance do the following:
1. Make sure that the product level is below the Near Zone region
(0-1.6 ft (0-0.5 m) below the Upper Reference Point).
2. Start the Radar Configuration Tools (RCT).
3. Choose the Device Commands option from the View menu.
4. Open the Details folder.
5. Click the Trim Near Zone option.
6. Select the Update option and click the OK button.
NOTE!
The Trim Near Zone function should only be used for reducing impact from
constant disturbances. It is not suitable for occasional disturbances.
To reset the transmitter to factory settings do the following:
1. Start the Radar Configuration Tools (RCT).
2. Choose the Device Commands option from the View menu.
3. Open the Details folder.
4. Click the Trim Near Zone option.
5. Select the Reset to Factory Settings option and click the OK button.
Changing the Upper Null Zone
Measurements are not performed within the Upper Null Zone (UNZ). By
setting the UNZ parameter to zero, measurements can be performed in the
region close to the flange (Near Zone). However, it is very important that there
are no disturbances in that region if UNZ is set to zero.
If there are measurement problems in the upper part of the tank you may use
the Trim Near Zone function as described above.
If the desired measurement range is below the Near Zone, or if disturbing
objects are located below the Near Zone, the Upper Null Zone parameter can
be used to avoid measurements above a certain level.

Amplitude Threshold
Settings
The amplitude thresholds are automatically adjusted to appropriate values in
order to filter out noise and other non-valid measurements from the
measurement signal.
The amplitude of the measurement signal, i.e. the amplitude of the signal that
is reflected by the product surface, is related to the actual dielectric constant
of the product. The amplitude threshold that is used by the transmitter is
based on the parameter configuration of the current product dielectric
constant (see Section 5: Basic Configuration). Normally no other threshold
adjustment is needed, but if the transmitter still does not track the product
surface correctly it may be necessary to adjust the threshold values.
The Radar Configuration Tool (RCT) has a plot function allowing you to view
the reflections along the probe.
If the amplitude threshold is too high the product level is not detected as
illustrated in Figure 7-10.

disturbance was interpreted as the product surface, whereas the actual

The Rosemount 3308 has a high sensitivity due to its advanced signal processing and high signal to noise
ratio, which makes it able to handle various disturbances. However, the following circumstances should be
considered before mounting the transmitter.
• Single lead probes are preferred when there is a risk for contamination (because coating can result in
product bridging across the two leads for twin versions; between the inner lead and outer pipe for the
coaxial probe)
• PTFE probes are recommended for viscous or sticky applications. Periodic cleaning might be required
• Maximum error due to coating is 1 to 10% depending on probe type, dielectric constant, coating
thickness, and coating height above product surface
Coating on the probe should be avoided since the sensitivity of the transmitter may be decreased leading
to measurement errors. In viscous or sticky applications, periodic cleaning may be required.
For viscous or sticky applications, it is important to choose a suitable probe (see Table A-6 on page A-7).
Heavy coating that results in product bridging across the two probes for twin lead versions, or between the
pipe and the inner rod for coaxial probes, will cause erroneous level readings and must be prevented.
Single lead probes are preferred in this case. If a Twin Lead probe is required, regular cleaning may be
necessary.
How well the Rosemount 3308 transmitter measures in foamy applications depends upon the properties of
the foam; light and airy or dense and heavy, high or low dielectrics, etc. If the foam is conductive and
creamy the transmitter will probably measure the surface of the foam. If the foam is less conductive the
microwaves will probably penetrate the foam and measure the liquid surface.
In some applications, as ammonia, there is heavy vapor above the product surface that will influence the
level measurement. The Rosemount 3308 transmitter can be configured to compensate for the influence of
vapor.

Tank Connection and Probe
Tank Connection
The tank connection consists of a tank seal, a flange,
Tri-Clamp, or NPT or BSP/G threads.
Certain models of flanged Alloy and PTFE covered
probes have a tank connection design with a
protective flange plate of the same material as the
probe and with a backing flange in 316L / EN 1.4404.
The protective flange plate prevents the backing
flange from being exposed to the tank atmosphere.

To get best possible performance, the following must be
considered before installing the transmitter:
• Inlets should be kept at a distance in order to avoid product
filling on the probe
• Avoid physical contact between probes and agitators, as well
as applications with strong fluid movement unless the probe is
anchored
• Probe tie-down is recommended if the probe can move to
within 1 ft. (30 cm) of any object during operations
Flexible single lead probe with chuck.
• In order to stabilize the probe for side forces, it is possible to
fix or guide the probe to the tank bottom
• For optimal single lead probe performance in non-metallic
vessels, the probe must either be mounted with a 2-in. / DN 50 or larger metallic flange, or a metal sheet
with an 8-in. diameter (200 mm) or larger must be used (see the Reference Manual for placement)

Considerations
PRELIMINARY
Rosemount 3308
When installing a Rosemount 3308 transmitter in a chamber, the single lead probe is recommended.
The recommended minimum chamber diameter is 4 in. (100 mm) for Single Flexible probe and 3 in. (75 mm)
for the Single Rigid probe. The probe should be centered to prevent it touching the sides of the well.
The probe length determines if a Single Rigid or Single Flexible probe should be used:
• Less than 19.7 ft. (6.0 m):
Rigid Single Probe is recommended. Use a centering disc for probe > 3.3 ft. (1 m). If installation requires
less head-space, use a Flexible Single Probe with a weight and centering disc.
• More than 19.7 ft. (6.0 m):
Use Flexible Single Probe with a weight and centering disc.
A short weight is available for the single flexible SST probe. It is used for measuring close to the probe end
and shall be used where the measuring range must be maximized. The height is 2 in. (50 mm) and the
diameter is 1.5 in. (37.5 mm). The option code is W2.
If a heavier weight is needed, option code W3 can be used (height is 5.5 in. (140 mm) and the diameter is 1.5
in. (37.5 mm).
To prevent the probe from contacting the chamber or pipe wall, centering discs are available for
rigid single, flexible single, and flexible twin lead probes. The disc is attached to the end of the
probe. Discs are made of stainless steel, Alloy C-276, Alloy 400, or PTFE. See Table A-9 for
Dimension D. Table A-10 shows which centering disc diameter to choose for a particular pipe.

SAFETY MESSAGES
Procedures and instructions in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Explosions could result in death or serious injury:
Verify that the operating environment of the gauge is consistent with the appropriate
hazardous locations certifications.
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an Explosion-proof/Flameproof installation, do not remove the transmitter cover when
power is applied to the unit.
Failure to follow safe installation and servicing guidelines could result in death or
serious injury:
Make sure the transmitter is installed by qualified personnel and in accordance with
applicable code of practice.
Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
Do not perform any service other than those contained in this manual unless you are
qualified.
A safety isolator such as a zener barrier is always needed for intrinsic safety.

High voltage that may be present on leads could cause electrical shock:
Avoid contact with leads and terminals.
Make sure the main power to the Radar Transmitter is off and the lines to any other
external power source are disconnected or not powered while wiring the transmitter.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable
level of electrostatic charge under certain extreme conditions. Therefore, when the
probe is used in a potentially explosive atmosphere, appropriate measures must be
taken to prevent electrostatic discharge.
