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.
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 (charged or discharged) are regulated during transportation by the U.S. Department of
Transportation. They 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. Consult current regulations and requirements before shipping.

2.1 Theory of operation
The Rosemount™ 3308 Series is the first true wireless level transmitter that is based on the Time Domain
Reflectometry (TDR) principle. Low power nano-second-pulses are guided along a probe submerged 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 Figure 2-1). See
Figure 2-2 for a schematic overview of the signal processing.
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.

Reference peak
This peak is caused by the transition between transmitter and the tank vapor space or air. It is used by the
transmitter as a starting reference point for distance to the level surface.
Product surface peak
This peak indicates the product level and is caused by a reflection from the product surface.
Interface peak
This peak indicates the interface level. The peak is caused by reflection from the interface between an
upper product and a bottom product with a relatively high dielectric constant. This peak is identified
when the Measurement Mode is set to Product Level and Interface Level or Interface Level with
Submerged Probe.
Probe end peak
It is caused by reflection from the probe end. If the probe is grounded, the peak will be positive. If the
probe end is submerged in a high dielectric media, such as water, it will not be visible.
Upper reference point
The Upper Reference Point is located at the underside of the threaded adapter, transmitter flange, or Tri
Clamp, as illustrated in Figure 2-3 on page 5.

Figure 2-3. Upper Reference Point
Zero reference point
The Zero Reference Point is selected by the user and is usually located close to or at the bottom of the
tank. The Zero Reference Point can be set to any position in the tank by adjusting the Tank Height.
Tank height
The Tank Height is the distance from the Upper Reference Point to the Zero Reference Point. 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 be included.
Blind zones
The measuring range depends on probe type, dielectric constant of the product and installation
environment, and is limited by the Blind Zones at the very top and bottom of the probe. In the Blind
Zones, the accuracy exceeds ±1.18 in. (30 mm), and measurements may not be possible. Measurements
close to the Blind Zones will have reduced accuracy.
Figure 2-4 illustrates how the measuring range is related to the Blind Zones and the areas with reduced
accuracy. Values for different probe types and dielectric constants are presented in section “Accuracy
over measuring range” on page 114.

2.2 Wireless by Emerson™
The Emerson Wireless network is a self-organizing solution. Wireless field instruments send data to a
Gateway, directly or routed through any of the wireless devices in the network, as illustrated in
Figure 2-5. Multiple communication paths are managed and analyzed in parallel to assure optimal
communication and sustained network reliability even if obstructions are introduced.
Figure 2-5. Emerson Wireless Network
Gateways interface with existing host systems using industry standard protocols, and native integration
into DeltaV™ and Ovation™ is transparent and seamless.
Interference from other radios, WiFi, and EMC sources is avoided through Time Synchronized Channel
Hopping and Direct Sequence Spread Spectrum (DSSS). Also, a layered security implementing industry
standard Encryption, Authentication, Verification, Anti-Jamming, and Key Management ensures that
data transmissions are secure and received only by the Gateway.
2.3 Application characteristics
2.3.1 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 no effect on the measurement performance. The transmitter
handles flat or dish-bottom tanks equally well.

2.3.2 In-tank obstructions
The Rosemount 3308 Series 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, you have the option to either hang a weight at the probe
end (flexible probes only) or fix/guide the probe to the tank bottom.
2.3.3 Interface level measurement
Rosemount 3308 Series Transmitter is well suited for measuring the interface of oil and water, or other
liquids with significant dielectric differences.
Figure 2-6. Interface Level Measurement
All probes can be used for measuring interfaces. Single probes are the preferred choice in almost all
applications but depending on the application and installation geometries a coaxial probe or a flexible
twin probe may be a better fit.
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.
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

3.3 Review mounting considerations
Before installing the Rosemount 3308 Series Transmitter, consider recommendations for sufficient free
space, mounting position and special needs for non-metallic tanks.
3.3.1 Recommended mounting position
When finding an appropriate mounting position for the transmitter, the conditions of the tank must be
carefully considered. The transmitter should be mounted so that the influence of disturbing objects is
reduced to a minimum. For easy access to the transmitter make sure that it is mounted with sufficient
service space.
Figure 3-1. Mounting Position
The following guidelines should be considered when mounting the transmitter:
Do not mount close to inlet pipes.
Do not mount close to agitators. If the probe can move to within 12 in. (30 cm) away from an agitator,
the probe should be anchored. See “Anchor the probe” on page 33 for more information.
If the probe tends to sway due to turbulent conditions in the tank, the probe should be anchored. See
“Anchor the probe” on page 33 for more information.
Avoid mounting close to heating coils.
Position the probe such that it is subject to a minimum of lateral force.
Make sure the probe does not come into contact with the nozzle or other objects in the tank.

Make sure the nozzle does not extend into the tank.
Note
Violent fluid movements causing high sideway forces may break rigid probes.
If the probe is mounted close to a wall, nozzle or other tank obstruction, noise might appear in the level
signal. Therefore the following minimum clearance, according to Table 3-1, must be maintained.

3.3.4 Installation in still pipe/chamber
General chamber considerations
A chamber or pipe installation is the preferred option due to the increase in stability and performance of
the transmitter. When selecting a smaller diameter chamber or pipe (such as 2-in.) a flexible probe is not
suitable due to the chance of it coming into contact with the walls, and relatively large side inlets may
interfere with the signal.
When gas lift and/or turbulence may occur (e.g. boiling hydrocarbons), a 3- or 4-in. chamber/pipe
diameter is recommended for maximum measurement reliability. This is especially true in high pressure
and high temperature installations.
Rosemount 9901 Chamber
Rosemount 9901 allows external mounting of process level instrumentation. It supports a variety of
process connections, and optional drain and vent connections. The Rosemount 9901 chamber is
designed to the ASME B31.3 standard, and is Pressure Equipment Directive (PED) compliant. Use option
code XC to order together with the Rosemount 3308 Series Transmitters.
Figure 3-7. Side-and-Side and Side-and-Bottom Chambers
The probe length to use for a Rosemount 9901 chamber can be calculated with this formula:
Side-and-side dimension:
Probe length=Centre-to-centre dimension + 19 in. (48 cm)
Side-and-bottom dimension:
Probe length=Centre-to-centre dimension + 4 in. (10 cm)
Use a centering disc the same diameter as the chamber if the probe length >3.3 ft. (1 m). See Table 3-5
on page 28 for which disc to use.

Existing chamber
A Rosemount 3308 Series Transmitter is the perfect replacement in an existing displacer chamber.
Proprietary flanges are offered, enabling use of existing chambers to make installation easy.
Figure 3-8. Existing Displacer Chamber
Considerations when changing to Rosemount 3308 Series:
The 3308 Series flange choice and probe length must be correctly matched to the chamber. Both
standard ANSI and EN (DIN), as well as proprietary chamber flanges, are available. See Table A-19 on
page 146 to identify the proprietary flanges.
See Table 3-5 on page 28 for guidelines on which disc size to use.
See Table 3-3 for guidelines on the required probe length.
Table 3-3. Required Probe Length in Chambers
For additional information, see the Replacing Displacers with Guided Wave Radar Technical Note.
Probe type in chamber considerations
When installing a Rosemount 3308 in a chamber, the single lead probe is recommended. 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). When mounting space is limited, 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.
PTFE covered probes are not recommended for chamber/pipe installations.

3.4.2 Shorten the probe
In order to leave some clearance distance between the probe end and the tank bottom, the probe might
have to be shortened. The goal is to have the probe hang straight so that it does not touch the wall. 2 in.
(5 cm) is a suggested value. The probe can be shortened in field. Use the following form to calculate the
probe length:
Probe Length = Tank height - 2 in. (5 cm)
After shortening the probe make sure to update the transmitter configuration to the new probe length,

3.5 Anchor the probe
In turbulent tanks it may be necessary to fix the probe. Depending on the probe type, different methods
can be used to guide the probe to the tank bottom. This may be needed in order to prevent the probe
from hitting the tank wall or other objects in the tank, as well as preventing a probe from breaking.
3.5.1 Flexible single/twin lead probe
The flexible single lead probe itself can be used for anchoring. Pull the probe rope through a suitable
anchoring point, e.g. a welded eye, and fasten it with a chuck.
The length of the loop will add to the Blind Zone. The location of the chuck will determine the beginning

3.7 Ground the device
The Rosemount 3308 Series Wireless Guided Wave Radar transmitter operates with the housing
grounded or floating. Floating systems can cause extra noise that may affect many types of readout
devices. If the signal appears noisy or erratic, grounding at a single point may solve the problem.
Grounding of the electronics enclosure should be done in accordance with local and national installation
codes. Grounding is accomplished by using the external case grounding terminal.
Non-metallic tanks
Ground device on non-metallic tanks (e.g. fiberglass tanks) to prevent electrostatic charge build-up.
There is one grounding screw connection provided, located on the housing, see Figure 3-19. The ground
screw is identified by a ground symbol:
Figure 3-19. Ground Screw
Note
Always use facility recommended wiring practices.
Note
Flexible twin lead probe or coaxial probe are the recommended choice for non-metallic tanks. Single
lead probes are not suited for non-metallic tanks or open atmosphere applications, due to high
susceptibility to strong electromagnetic fields.

4.6.3 Configure update rate
The Update Rate is the frequency at which a new measurement is transmitted over the wireless network.
The default update rate is 1 minute. This may be changed at commissioning, or at any time via AMS
Wireless Configurator or a Field Communicator. The Update Rate is user selectable from 4 seconds to 60
minutes.
1. Select Configure > Guided Setup > Wireless Setup.
2. Select Configure Update Rate, and follow the instructions.
Note
Make sure to set the Update Rate so that there is enough safety margin in the system for high/low alerts.
If the time between each update is too long, the high/low alerts may be triggered too late.
Run Check Level Response to make sure that configured Update Rate is sufficient for the application,
refer to section “Optional setup” on page 73.
4.6.4 Obtain network ID and join key
In order to communicate with the Wireless Gateway, and ultimately the host system, the transmitter
must be configured to communicate on the wireless network. This step is the wireless equivalent of
connecting wires from a transmitter to the host system.
The Network ID and Join Key may be obtained from the Wireless Gateway's integrated web interface on
the Setup > Network > Settings page, as shown in Figure 4-6.

4.6.5 Enter network ID and join key
The devices must be configured with the same Network ID and Join Key as the Gateway in order to join
the network. Use a Field Communicator or AMS Wireless Configurator to enter the Network ID and Join
Key so they match the Network ID and Join Key of the Gateway.
1. Select Configure > Guided Setup > Wireless Setup.
2. Select Join Device to Network, and follow the instructions.
If the device is not to be commissioned yet, remove the power module and fasten the housing cover. This
is to conserve power module life and to ensure safe transmitter transportation. The power module
should be inserted only when the device is ready to be commissioned.
4.6.6 Verify device joins network
Network connection can be verified in four ways, further described in this section:
1. At the device display
2. Using the AMS Wireless Configurator
3. In the Wireless Gateway's integrated web interface
4. Using the Field Communicator
If the Rosemount 3308 Series was configured with the Network ID and Join Key, and sufficient time has
passed, the transmitter should be connected to the network. It usually takes a few minutes for the device
to join the network. If the device has not joined the network, please see “Wireless network troubleshoot-
ing” on page 92.
Verify by device display
To verify that the device is connected to the network by the display, press the DIAG button. The display
will show: the Tag, Device Serial Number, Software Revision, Network ID, Network Connection Status,
and Device Status screens. Refer to “Diagnostic button screen sequence” on page 78.
When the network diagnostic status is displayed as “NETWK OK”, the device has successfully joined the
network. When joining the wireless network, the status displayed will be changed through the sequence
until the device finally has joined the network. Figure 4-7 on page 69 presents the different network

Communicator which may be useful for service and troubleshooting of Rosemount™ 3308 Series
Transmitter.
6.4.1 Reading the echo curve
The AMS Wireless Configurator and Field Communicator have powerful tools for advanced troubleshoot-
ing. By using the Echo Curve function you get a view of the tank signal. Measurement problems can be
solved by studying the position and amplitude of the different peaks.
To read the echo curve:
1. Select Service Tools > Echo Tuning > Echo Curve.
2. AMS Wireless Configurator: In the dialog box, select Next > to start reading the echo curve. The
reading may take several minutes.
Field Communicator: Select Echo Curve Graph and follow the on-screen instructions. The reading may
take several minutes.

6.4.2 Adjusting thresholds
Measurement with the Rosemount 3308 is based on the fact that the radar signal pulses are reflected by
the product surface and the interface between two liquids. Signal amplitude thresholds are used to
separate the measurement signal from disturbing echoes and noise.
By default, the amplitude thresholds are automatically adjusted to appropriate values in order to filter
out noise and other non-valid measurements from the measurement signal, as illustrated in Figure 6-3.
The configured Upper Product Dielectric Constant is used for setting the automatically calculated
amplitude thresholds. Normally no other threshold adjustment is needed. But if the transmitter still does
not track for example the product surface, it may be necessary to manually adjust the thresholds.
Figure 6-3. Threshold Principle
The different amplitude thresholds used for the Rosemount 3308 Series Transmitter are described in
section “Thresholds” on page 176.
Note
Before changing the amplitude thresholds, check that the Upper Product Dielectric Constant parameter
is set as accurately as possible. The Upper Product Dielectric Constant is used for setting the
automatically calculated amplitude thresholds.
A. The echo peak is below the threshold (dotted line) and is suppressed by the device.

Guidelines for setting the surface threshold
Before changing the Surface Threshold, make sure the product level is at least 20 in. (0.5 m) from the
lower side of the device flange.
Set the Surface Threshold to about 1/3 of the weakest surface echo amplitude in the measuring range.
Surface Thresholds should never be set to values less than 4 Cnts.
Make sure to include a 3 Cnts margin between the Surface Threshold and the surface echo amplitude
over the entire measuring range.
The Surface Threshold should be at least 3 Cnts greater than the amplitude of disturbances.
Contact your local Emerson™ representative if the transmitter is still having difficulties to track the
product surface after applying the guidelines.

Guidelines for setting the interface threshold
The Interface Threshold should be approximately 50% of the interface signal amplitude.
If possible, Interface Threshold should be higher than Surface Threshold.
Procedure for adjusting thresholds
To adjust the amplitude thresholds:
1. Read the Echo Curve.
a. Start the Echo Curve reading, refer to “Reading the echo curve” on page 93.
b. View the Echo Curve plot and check the relation between amplitude threshold and
corresponding signal amplitude peak.
2. Adjust the Threshold.
a. Select Service Tools > Echo Tuning > Thresholds.
b. Under Threshold Control, select User Defined.
c. If using Field Communicator, select Send. The Threshold values can now be changed.
d. Select desired Threshold to adjust, type the new value into the box, and then select Send. See
also “Guidelines for setting the surface threshold” on page 95.
Restore default thresholds
1. Select Service Tools > Echo Tuning > Thresholds.
2. Under Threshold Control, select Default (Automatic), and then select Send.
Example 1: Product surface peak not found
If the transmitter does not track the product surface correctly, it may be necessary to adjust the
threshold values. In Figure 6-4, the Surface Threshold is too high and as a result the product level will not
be detected. In a situation like this, the Surface Threshold has to be lowered so that the surface peak is
not filtered out.

If there are disturbing objects in the tank, the Surface Threshold must be carefully set to avoid locking on
the wrong amplitude peak. In Figure 6-5, the Surface Threshold is too low, and as a result the transmitter
has locked on a peak above the actual product surface. A disturbance was interpreted as the product
surface, since this was the first amplitude peak closest to device that went above Surface Threshold. The
actual product surface was interpreted as the interface or the probe end.
Figure 6-5. Surface Threshold Is Too Low
By adjusting the Surface Threshold the product surface is properly detected as illustrated in Figure 6-6.
Figure 6-6. Echo Curve Plot after Surface Threshold Was Adjusted
Example 2: Interface peak not found
In interface applications where the bottom product has a relatively low dielectric constant (<40), or if the
signal is attenuated in the upper product, the amplitude of the reflected signal from the interface is
relatively low and difficult for the transmitter to detect. In such a case it may be possible to detect the
reflected signal from the interface if the Interface Threshold is adjusted.
Figure 6-7 illustrates a situation where the Interface Threshold is too high. The signal amplitude peak at
the interface between the upper and lower products is not detected in this case.

6.5.2 Handling disturbances at the top of the tank
Adjusting the near zone threshold
The Near Zone Threshold is used to filter out disturbing echoes and noises at the top of the tank. By
default, this threshold is automatically calculated by the device, and is sufficient in most conditions.
However, in the case of unfavorable conditions, you might need to manually set the Near Zone
Threshold. This may for example be the case if a Single Lead probe is mounted in a narrow nozzle, if the
end of the nozzle protrudes into the tank, or if there are disturbing obstacles in the Near Zone (referred
to as the region between 0-3.3 ft. (0-1 m) below the Upper Reference Point.
Figure 6-13. Near Zone Threshold
Guidelines for setting the near zone threshold
The Near Zone Threshold must be higher than the Surface Threshold to have an effect. The threshold
in the near zone is set to the highest value of the configured Near Zone Threshold and Surface
Threshold.
The margin to waveform disturbances and noise must be at least 3 Cnts.
Procedure
To manually set the Near Zone Threshold function:
1. Read the Echo Curve.
a. Start the Echo Curve reading, refer to “Reading the echo curve” on page 93.
b. View the Echo Curve plot to find out if there are disturbing echoes close to the tank top.

Using the trim near zone function
The Trim Near Zone function is used to fine tune performance in the area close to the tank top. Normally
it is not necessary to use the function, but if you experience problems related to the nozzle, pipe, or
chamber installation, you may need to use this function.
Figure 6-14 describes the Trim Near Zone function and its effect on the echo curve. This effect is only
visible if measurement conditions so require.
Figure 6-14. Echo Curve before and after Trim Near Zone
Note
Make sure the product level is below the Near Zone region (0-3.3 ft. (0-1 m) below the Upper Reference
Point) before performing the Trim Near Zone.
Note
The Trim Near Zone function should only be used for reducing impact from stationary disturbances. For
occasional disturbances, use the Near Zone Threshold.
To use the Trim Near Zone function:
1. Select Service Tools > Echo Tuning and click Near Zone.
2. Under Near Zone Compensation, select Trim Near Zone and follow the on-screen instructions.
Changing the upper null zone
Measurements are not performed within the Upper Null Zone (UNZ). The Upper Null Zone can be
extended to block out disturbing echoes close to the tank top, caused by for example a narrow nozzle
with rough walls, obstacles close to the probe, or a nozzle that protrudes into the tank. See Figure 6-16.

6.5.3 Interface measurements with fully submerged probes
The Measurement Mode Interface Level with Submerged Probe is used to handle interface
measurements when the product level is not visible, for example in a full chamber pipe as illustrated in
Figure 6-17. In this case the probe is fully submerged 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. 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 submerged.
To set the Measurement Mode to Interface Level with Submerged Probe:
1. Select Configure > Manual Setup > Level Setup > Environment.
2. Under Measurement Mode, select Interface Level with Submerged Probe (Interface Only in Field
Communicator), and then select Send.
Note
Do not set Measurement Mode to Interface Level with Submerged Probe in “standard” applications
when both Product Level and Interface Level are measured.

6.5.4 Noise or weak surface echoes
In difficult applications where the surface echo peak is low compared to the noise, it is recommended to
set the Performance Mode to High Performance. A low surface peak compared to the noise might be
caused by a turbulent surface, foam, low dielectric constant, plastic tanks, and so on.(1)
If the Performance Mode is set to High Performance, each update is based on an increased number of
measurements (radar sweeps), which gives improved accuracy and robustness, as well as decreased
noise in the output value. However, the battery life is significantly reduced (between 40-60 percent).
1. Select Service Tools > Echo Tuning > Advanced.
2. Under Performance Mode, select High Performance, and then select Send.

A.1.3 Interface measuring range
The maximum allowable upper product
thickness/measuring range is primarily determined by the
dielectric constants of the two liquids.
Typical applications include interfaces between oil/oil-like
and water/water-like liquids, with a low (<3) dielectric
constant for the upper product and a high (>20) dielectric
constant for the lower product. For such applications, the
maximum measuring range is limited by the length of the
coaxial and rigid single lead probes.
For flexible probes, the maximum measuring range is
reduced by the maximum upper product thickness,
according to the diagram below. However, characteristics
may vary between the different applications.

A.1.4 Accuracy over measuring range
The measuring range depends on probe type, dielectric
constant of the product and installation environment, and is
limited by the Blind Zones at the very top and bottom of the
probe. In the Blind Zones, the accuracy exceeds ±1.18 in.
(30 mm), and measurements may not be possible.
Measurements close to the Blind Zones will have reduced
accuracy.
The following conditions will impact the Blind Zones:
If the single lead probes or twin probes are installed in a
nozzle, the nozzle height shall be added to the specified
Upper Blind Zone.
The measuring range for the PTFE covered flexible single
lead probe includes the weight when measuring on a high
dielectric media.
Figure A-2, Figure A-3, Figure A-4, and Figure A-5 illustrate
the accuracy over measuring range at reference condition
using the Trim Near Zone function, with alternating probe
types and varying dielectric constant of the product.

A.2.8 Interface measurements
The Rosemount 3308 Series is well suited for interface
measurements, including applications where the probe is
fully submerged in the liquid.
Figure A-8. Interface Level Measurement
If interface is to be measured, follow these criteria:
The dielectric constant of the upper product should be
known and should not vary. The AMS Wireless
Configurator and Field Communicator have a built-in
Dielectric Constant Guide 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 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 the single lead and flexible
twin lead probes.
Minimum detectable upper product thickness is 4 in. (10
cm) when the upper product is oil (DC=2.2) and the lower
product is water (DC=80).
For guidelines on emulsion situations, consult your local
Emerson™ representative.

Interface Measurement Technical Note.

A.3 Physical specifications
A.3.1 Material selection
Emerson provides a variety of Rosemount product with
various product options and configurations including
materials of construction that can be expected to perform
well in a wide range of applications. The Rosemount product
information presented is intended as a guide for the
purchaser to make an appropriate selection for the
application. It is the purchaser’s sole responsibility to make
a careful analysis of all process parameters (such as all
chemical components, temperature, pressure, flow rate,
abrasives, contaminants, etc.), when specifying product,
materials, options and components for the particular
application. Emerson is not in a position to evaluate or
guarantee the compatibility of the process fluid or other
process parameters with the product, options,
configuration or materials of construction selected.
A.3.2 Tank connection
The tank connection consists of a tank seal, a flange, Tri
Clamp, or NPT or BSPP (G) threads. See “Dimensional
drawings” on page 139.
Certain models of flanged alloy and PTFE covered probes
have a tank connection design with a protective plate of the
same material as the probe (see Figure A-9). This is to
prevent the 316L/EN 1.4404 SST flange from being exposed
to the tank atmosphere.

blind flanges. For Proprietary Fisher and Masoneilan flanges,
see “Proprietary Flanges” on page 146.
A.3.5 Probes
Probe versions
Flexible single lead, rigid single lead, segmented rigid single
lead, flexible twin lead, and coaxial.
Total probe length
This is defined from the Upper Reference Point to the end of
the probe (weight included, if applicable).
Figure A-10. Total Probe Length
Select the probe length according to the required
measuring range (the probe must be hung and fully
extended through the entire distance where level readings
are desired).
Cut-to-fit probes
All probes can be cut in field except for the PTFE covered
probe.
However, there are some restrictions for the coaxial probe:
Probes over 4.1 ft. (1.25 m) can be cut up to 2 ft. (0.6 m).
Shorter probes can be cut to the minimum length of 1.3 ft.
(0.4 m).

D.3 Configuration parameters
This section presents a brief introduction to all configuration parameters.
The Rosemount™ 3308 Series Transmitter can be configured for level, volume, interface level, interface
distance measurements, and interface thickness.
The Rosemount 3308 Series Transmitter can be pre-configured according to the ordering specifications
in the Configuration Data Sheet.
D.3.1 Guided setup
Basic setup
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 Constant must be given as well.

Figure D-3. Upper Reference Point
Probe type
The transmitter is designed to optimize measurement performance for each probe type. 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, or if you have
installed a spare transmitter)
Select the type of probe that is mounted to the transmitter. Select User Defined probe if your probe can
not be found in the list or if you have done modifications to a standard probe.
Probe length
The probe length is the distance between the Upper Reference Point and the end of the probe, see Figure
D-3 on page 162. If a weight is used at the end of the probe it shall be included.
This parameter is pre-configured at factory. The probe length must be changed if the probe is shortened,
or if you have ordered a spare transmitter head.
Tank height
The Tank Height is the distance from the Upper Reference Point to the bottom of the tank (Zero
Reference Point). See Figure D-2 on page 161.
The transmitter measures the distance to the product surface and subtracts this value from the Tank
Height to determine the level.
When setting the Tank Height, keep in mind that this value is used for all level measurements performed
by the Rosemount 3308 Series Transmitter. The Tank Height must be set in linear (level) units, such as
feet or meters, regardless of primary variable assignment.
Mounting type
Select option best describing how device is mounted on the tank.

Nozzle height
The distance between the Upper Reference Point (normally the lower side of the device flange) and the
end of the nozzle. Note that nozzle may extend into the tank (which should be included in the height).
Measurement mode
Select the Measurement Mode to use in the device. Some modes require software options to be enabled
in the device. You can upgrade the device to enable more software options.
Interface Level with Submerged Probe is used for applications where the probe is fully immersed in liquid. In
this mode the transmitter ignores the upper product level. See “Interface measurements with fully
submerged probes” on page 105 for more information.
Note
Only use Interface Level with Submerged Probe for applications where interface is measured for a fully
immersed probe.
Upper product media
Approximate DC value selected from list based on tank content.
Upper product dielectric constant
Enter the Upper Product Dielectric Constant (DC) as accurately as possible. This value is used for setting
the automatically calculated amplitude thresholds. In addition the dielectric constant of the upper
product is essential for calculating the interface level and the upper product thickness. The default value
for the Upper Product Dielectric Constant is 2.
For level measurements, the Upper Product Dielectric Constant parameter corresponds to the dielectric
constant of the product in the tank.
If the dielectric constant of the lower product is significantly smaller than the dielectric constant of
water, you may need to make special adjustments. The dielectric constant of water is 80. See section
“Example 2: Interface peak not found” on page 97 for further information.
In case the dielectric constant is unknown, then use the Dielectric Constant Guide embedded in the AMS
Wireless Configurator as help when configuring the DC.
The AMS Wireless Configurator includes a Dielectric Chart which lists the dielectric constants of a range
of products. AMS Wireless Configurator also includes a tool which allows you to calculate dielectric
constants based on measurements of the Upper Product Thickness.
1. Select Configure > Manual Setup > Level Setup > Environment.
2. Select Dielectric Constant Guide and follow the on-screen instructions.
Maximum product level rate
Fastest rate that may occur in the monitored process to (partially) fill or empty this tank. Will be used to
calculate the maximum level change between updates. Note that product level rate may be higher
during upset conditions.
Note
If the tank is filling or emptying at a high rate, set a faster Update Rate to make sure there is enough
safety margin in the system for High/Low Alerts.
Run Check Level Response to make sure that configured Update Rate is sufficient for the application,
refer to section “Optional setup” on page 73.

Environment
Vapor dielectric constant
Enter the dielectric constant (DC) for the vapor gas in the tank. For normal air the vapor DC is close to 1.
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 air. Normally this value
does not need to be changed since the effect on measurement performance is very small for most
vapors.
Max upper product thickness
Configure the maximum possible thickness for the upper product in this tank. This is the maximum
thickness the device will expect for this tank.
Volume
Calculation method
Select method for volume calculation based on tank shape or a strapping table. Strapping table requires
entering level-volume pairs in a table.
Diameter (L1)

Strapping table
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 20 points can be added to
the strapping table.
If tank type Strapping Table was chosen, enter how many entries you will use and the actual level and

Signal quality alert
Signal Quality is the product surface echo amplitude compared to the surface threshold and noise. The
Signal Quality spans from 0 to 10. A low value means that there is a risk for the noise peak to be mistaken
for the product surface peak.
Build up on the probe and different surface conditions are factors that can result in a low Signal Quality
value. By setting an alert, the Signal Quality value can be used to schedule maintenance to clean the
probe.
Note
The Signal Quality depends on probe type and application conditions, as well as the condition of the
probe. Even if the probe is clean, Signal Quality may not be a 10.
Suitable alert limits vary from application to application. Appropriate value can be determined by
logging Signal Quality over time and viewing maximum/minimum values. The Signal Quality Alert limit
should be at least 1, but a better guideline is 2-3.
A. Actual tank bottom may look like this.
B. Using only three strapping points results in a level-to-volume profile that is more angular than the actual shape.

Then it will output level according to Lost Measurement Behavior, if still lost.
For an application where problems with lost measurement due to noise or weak surface echoes are
experienced, this parameter value could typically be increased.
The Hold Time value presents for how long the device will hold the current level. The time the current

Figure D-10. Thresholds
Threshold control
Thresholds can be automatically calculated by device or manually set by user. This setting is valid for all
thresholds on the Thresholds tab (Surface, Interface Reference, and Probe End Thresholds).
Surface threshold
Threshold to filter out noise in the echo curve for detection of the Surface. Noise below the threshold is
suppressed. The first echo peak closest to the device that crosses and is above the Surface Threshold is
the surface echo.
Interface threshold
Threshold to filter out noise in the echo curve for detection of the Interface. The first echo peak after the
surface echo that crosses and is above the Interface Threshold is the interface echo.
Reference threshold
Threshold to filter out noise in the echo curve for detection of the Reference peak. The reference peak is
a strong negative echo very close to the device.
Probe end threshold
Threshold to filter out noise in the echo curve for detection of the Probe End peak. The probe end peak is
a fairly strong positive or negative echo (depending on probe type) that is present at the probe end when
tank is empty.

Near zone threshold
Threshold control
The Near Zone Threshold can be automatically calculated by device or manually set by user.
Threshold
Threshold to filter out noise in a zone near the device. Noise below the threshold is suppressed. This
threshold replaces the Surface threshold in the zone where it is applicable.
Distance
Distance from Upper Reference Point (normally the lower side of device flange) to point where the near
zone threshold ends.
Near zone trimming
Trim near zone
Select to activate trimming.
The Trim Near Zone method is used to fine tune performance in the area close to the tank top. This
function is normally not used. Trim Near Zone is typically used if there are problems related to the nozzle.
For more information see section “Using the trim near zone function” on page 103.
Near zone has been trimmed
Indicates if the Trim Near Zone method has been used for this device.
