Configuration and Use Manual Quick start
MMI-20016855 June 2019
2 Quick start
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for process
measurement.
Procedure
1. Ensure that all transmitter and sensor covers and seals are closed.
DANGER
To prevent ignition of flammable or combustible atmospheres, ensure that all covers and seals are
tightly closed. For hazardous area installations, applying power while housing covers are removed or
loose can cause an explosion.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. The transmitter is self-switching and
will automatically detect the supply voltage. When using DC power, a minimum of 1.5 amps of startup
current is required. During this period, Alert 009 is active. The diagnostic routines should complete in
approximately 30 seconds. The status LED will turn green when the startup diagnostics are complete. If
the status LED exhibits different behavior, an alert is active.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to
10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power has been off long
enough to allow components to reach ambient temperature, allow the electronics to warm up for
approximately 10 minutes before relying on process measurements. During this warm-up period, you may
observe minor measurement instability or inaccuracy.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
Procedure
1. Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and checks for error
conditions. During the power-up sequence, Alert A009 is active. This alert should clear automatically
when the power-up sequence is complete.
2. Check the status LED on the transmitter.

2.3 Make a startup connection to the transmitter
For all configuration tools except the display, you must have an active connection to the transmitter to
configure the transmitter. Follow this procedure to make your first connection to the transmitter.
Procedure
Identify the connection type to use, and follow the instructions for that connection type in the appropriate
appendix. Use the default communications parameters shown in the appendix.
Communications tool Connection type to use Instructions
ProLink III Modbus/RS-485 Using ProLink III with the transmitter
Field Communicator HART Using a Field Communicator with the
transmitter
2.4 Characterize the flowmeter (if required)
Display
ProLink III Device Tools → Calibration Data
Field Communicator Configure → Manual Setup → Characterize
Characterizing the flowmeter adjusts your transmitter to match the unique traits of the sensor it is paired
with. The characterization parameters (also called calibration parameters) describe the sensor’s sensitivity to
flow, density, and temperature. Depending on your sensor type, different parameters are required. Values for
your sensor are provided by Micro Motion on the sensor tag or the calibration certificate.
Tip
If your flowmeter was ordered as a unit, it has already been characterized at the factory. However, you should
still verify the characterization parameters.
Procedure
1. Specify Sensor Type.
• Straight-tube (T-Series)
Not available
• Curved-tube (all sensors except T-Series)
2. Set the flow characterization parameters. Be sure to include all decimal points.
• For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and FFQ.

3. Set the density characterization parameters.
• For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2.
• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown as DT.)

2.4.2 Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character FT value.
They are provided on the sensor tag.
Both values contain decimal points. The 10-character string is called either Flowcal or FCF.
If your sensor tag shows the FCF and the FT values separately and you need to enter a single value,
concatenate the two values to form the single parameter value, retaining both decimal points.
2.4.3 Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
Density calibration parameters are typically on the sensor tag and the calibration certificate.
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. If you cannot find a Dens A or D1 value,
enter 0.001 g/cm3.
• 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 you cannot find a Dens B or D2 value,
enter 0.998g/cm3 .
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 this sample tag, this value is shown as
12500.
• For K2, enter the second 5 digits of the density calibration factor. In this sample tag, this value is shown as
14286.

If your sensor does not show an FD value, contact customer service.
If your sensor tag does not show a DT or TC value, enter the last 4 characters of the density calibration factor.
In the sample tag shown above, the value is shown as 4.44.
Do not confuse the Meter Factor line on the pictured sensor tag with any meter factor settings discussed in
this manual.
The Meter Type value is not relevant on a 9739 MVD transmitter.
2.5 Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available
method.
Procedure
• Read the value for Mass Flow Rate on the transmitter display.
• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables
panel.
• Connect to the transmitter with the Field Communicator and read the value for Mass Flow Rate.
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues.

2.6 Verify the zero
Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field
zero can improve measurement accuracy.
The zero verification procedure analyzes the Live Zero value under conditions of zero flow, and compares it to
the Zero Stability range for the sensor. If the average Live Zero value is within a reasonable range, the zero
value stored in the transmitter is valid. Performing a field calibration will not improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the meter unless one of the
following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Procedure
1. Allow the flowmeter to warm up for at least 20 minutes after applying power.
2. Run the process fluid through the sensor until the sensor temperature reaches the normal process
operating temperature.
3. Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if
available.
4. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of
process fluid.
5. From ProLink III, choose Device Tools → Calibration → Zero Verification and Calibration → Verify
Zero and wait until the procedure completes.
6. Observe the drive gain, temperature, and density readings. If they are stable, check the Live Zero or
Field Verification Zero value. If the average value is close to 0, you should not need to zero the meter.
7. If the zero verification procedure fails:
a) Confirm that the sensor is completely blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
b) Verify that the process fluid is not flashing or condensing, and that it does not contain particles
that can settle out.
c) Remove or reduce sources of electromechanical noise if appropriate.
d) Repeat the zero verification procedure.
e) If it fails again, zero the meter.
Postrequisites
Restore normal flow through the sensor by opening the valves.

2.6.1 Terminology used with zero verification and zero calibration
Term Definition
Zero In general, the offset required to synchronize the left pickoff and the right pickoff under
conditions of zero flow. Unit = microseconds.
Factory Zero The zero value obtained at the factory, under laboratory conditions.
Field Zero The zero value obtained by performing a zero calibration outside the factory.
Prior Zero The zero value stored in the transmitter at the time a field zero calibration is begun. May
be the factory zero or a previous field zero.
Manual Zero The zero value stored in the transmitter, typically obtained from a zero calibration
procedure. It may also be configured manually. Also called “mechanical zero” or “stored
zero”.
Live Zero The real-time bidirectional mass flow rate with no flow damping or mass flow cutoff
applied. An adaptive damping value is applied only when the mass flow rate changes
dramatically over a very short interval. Unit = configured mass flow measurement unit.
Zero Stability A laboratory-derived value used to calculate the expected accuracy for a sensor. Under
laboratory conditions at zero flow, the average flow rate is expected to fall within the
range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model
has a unique Zero Stability value. Statistically, 95% of all data points should fall within the
range defined by the Zero Stability value.
Zero Calibration The procedure used to determine the zero value.
Zero Time The time period over which the Zero Calibration procedure is performed. Unit = seconds.
Field Verification Zero A 3-minute running average of the Live Zero value, calculated by the transmitter. Unit =
configured mass flow measurement unit.
Zero Verification A procedure used to evaluate the stored zero and determine whether or not a field zero
can improve measurement accuracy.

A special measurement unit is a user-defined unit of measure that allows you to report process data, totalizer
data, and inventory data in a unit that is not available in the transmitter. A special measurement unit is
calculated from an existing measurement unit using a conversion factor.
Note
Although you cannot define a special measurement unit using the display, you can use the display to select an
existing special measurement unit, and to view process data using the special measurement unit.
Procedure
1. Specify Base Mass Unit.
Base Mass Unit is the existing mass unit that the special unit will be based on.
2. Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3. Calculate Mass Flow Conversion Factor as follows:
a) x base units = y special units
b) Mass Flow Conversion Factor = x ÷ y
The original mass flow rate value is divided by this value.
4. Enter Mass Flow Conversion Factor.
5. Set Mass Flow Label to the name you want to use for the mass flow unit.
6. Set Mass Total Label to the name you want to use for the mass total and mass inventory unit.

4.1.2 Configure Flow Damping
Display Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Flow Damping
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies
the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end
of the interval, the internal value will reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
• The default value is 0.8 seconds.
• The flow damping range is 0 to 51.2 seconds when Update Rate is set to Normal.
• The flow damping range is 0 to 10.24 seconds when Update Rate is set to Special.
Tip
• A high damping value makes the process variable appear smoother because the reported value changes
slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes
more quickly.
• The combination of a high damping value and rapid, large changes in flow rate can result in increased
measurement error.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement
because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time
between the actual measurement and the reported value.
The value you enter is automatically rounded down to the nearest valid value.
Configuration and Use Manual 23
Configure process measurement Configuration and Use Manual
June 2019 MMI-20016855
If Flow Damping is set to Normal, the valid values are: 0, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, 25.6, and 51.2.
If Flow Damping is set to Special, the valid values are: 0, 0.04, 0.08, 0.16, 0.32, 0.64, 1.28, 2.56, 5.12, and
10.24.
Effect of flow damping on volume measurement
Flow damping affects volume measurement for liquid volume data. Flow damping also affects volume
measurement for gas standard volume data. The transmitter calculates volume data from the damped mass
flow data.
Interaction between Flow Damping and mA Output Damping
In some circumstances, both Flow Damping and mA Output Damping are applied to the reported mass flow
value.
Flow Damping controls the rate of change in flow process variables. mA Output Damping controls the rate
of change reported via the mA Output. If mA Output Process Variable is set to Mass Flow Rate, and both
Flow Damping and mA Output Damping are set to non-zero values, flow damping is applied first, and the
added damping calculation is applied to the result of the first calculation.
4.1.3 Configure Mass Flow Cutoff
Display Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Mass Flow Cutoff
Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All mass flow rates
below this cutoff will be reported as 0.
Procedure
Set Mass Flow Cutoff to the value you want to use.
The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the factory. The
recommended value is 0.5% of the nominal flow rate of the attached sensor. See the sensor specifications.
Leaving Mass Flow Cutoff at 0 is not recommended.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from the actual mass data
rather than the reported value.
Volume flow has a separate Volume Flow Cutoff that is not affected by the Mass Flow Cutoff value.
Interaction between Mass Flow Cutoff and mA Output Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as measured. mA
Output Cutoff defines the lowest flow rate that will be reported via the mA Output. If mA Output Process

Variable is set to Mass Flow Rate, the mass flow rate reported via the mA Output is controlled by the higher of
the two cutoff values.
Mass Flow Cutoff affects all reported values and values used in other transmitter behavior (e.g., events
defined on mass flow).
mA Output Cutoff affects only mass flow values reported via the mA Output.
Cutoff interaction with mA Output Cutoff lower than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 10 g/sec
• Mass Flow Cutoff: 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0 will be used in all
internal processing.
Cutoff interaction with mA Output Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 15 g/sec
• Mass Flow Cutoff: 10 g/sec
Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
— The mA Output will report zero flow.
— The Frequency Output will report the actual flow rate, and the actual flow rate will be used in all
internal processing.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0 will be used in all
internal processing.

The two-phase flow parameters control how the transmitter detects and reports two-phase flow (gas in a
liquid process or liquid in a gas process).
Note
Two-phase flow is also referred to as slug flow.
Procedure
1. Set Two-Phase Flow Low Limit to the lowest density value that is considered normal in your process.
Values below this will cause the transmitter to post Alert A105 (Two-Phase Flow).
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the occurrence of twophase flow alerts that are not significant to your process, set Two-Phase Flow Low Limit slightly below
your expected lowest process density.

Configuration and Use Manual Configure process measurement
MMI-20016855 June 2019
You must enter Two-Phase Flow Low Limit in g/cm³, even if you configured another unit for density
measurement.
The default value for Two-Phase Flow Low Limit is 0.0 g/cm³. The range is 0.0 to 10.0 g/cm³.
2. Set Two-Phase Flow High Limit to the highest density value that is considered normal in your process.
Micro Motion recommends leaving Two-Phase Flow High Limit at the default value.
Values above this will cause the transmitter to post Alert A105 (Two-Phase Flow).
You must enter Two-Phase Flow High Limit in g/cm³, even if you configured another unit for density
measurement.
The default value for Two-Phase Flow High Limit is 5.0 g/cm³. The range is 0.0 to 10.0 g/cm³.
3. Set Two-Phase Flow Timeout to the number of seconds that the transmitter will wait for a two-phase
flow condition to clear before posting the alert.
The default value for Two-Phase Flow Timeout is 0.0 seconds, meaning that the alert will be posted
immediately. The range is 0.0 to 60.0 seconds.
The Two-Phase Flow alert is set immediately. The flow rate will hold the last measured value for the
Timeout time. Then the flow rate will report zero flow. If the density goes back in range, the error clears
immediately.
Detecting and reporting two-phase flow
Two-phase flow (gas in a liquid process or liquid in a gas process) can cause a variety of process control issues.
By configuring the two-phase flow parameters appropriately for your application, you can detect process
conditions that require correction.
Micro Motion recommends leaving Two-Phase Flow High Limit at the default value.
A two-phase flow condition occurs whenever the measured density goes below Two-Phase Flow Low Limit or
above Two-Phase Flow High Limit. If this occurs:
• A two-phase flow alert is posted to the active alert log.
• All outputs that are configured to represent flow rate hold their last pre-alert value for the number of
seconds configured in Two-Phase Flow Timeout.
If the two-phase flow condition clears before Two-Phase Flow Timeout expires:
• Outputs that represent flow rate revert to reporting actual flow.
• The two-phase flow alert is deactivated, but remains in the active alert log until it is acknowledged.
If the two-phase flow condition does not clear before Two-Phase Flow Timeout expires, the outputs that
represent flow rate report a flow rate of 0.
If Two-Phase Flow Timeout is set to 0.0 seconds, the outputs that represent flow rate will report a flow rate of
0 as soon as two-phase flow is detected.

June 2019 MMI-20016855
ProLink III Device Tools → Configuration → Process Measurement → Density
Field Communicator Configure → Manual Setup → Measurements → Density → Density Damping
Density Damping controls the amount of damping that will be applied to the line density value.
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies
the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end
of the interval, the internal value will reflect 63% of the change in the actual measured value.
Procedure
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. For most applications, the default density damping setting is sufficient. The
range depends on the core processor type and the setting of Update Rate, as shown in the following table:
Update Rate setting Damping range
Normal 0 to 51.2 seconds
Special 0 to 40.96 seconds
Tip
• A high damping value makes the process variable appear smoother because the reported value changes
slowly.
• A low damping value makes the process variable appear more erratic because the reported value changes
more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement
because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time
between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. The valid values for Density
Damping depend on the setting of Update Rate.

Effect of Density Damping on volume measurement
Density Damping affects liquid volume measurement. Liquid volume values are calculated from the damped
density value rather than the measured density value. Density Damping does not affect gas standard volume
measurement.
Interaction between Density Damping and Added Damping
When the mA Output is configured to report density, both Density Damping and Added Damping are
applied to the reported density value.
Density Damping controls the rate of change in the value of the process variable in transmitter memory.
Added Damping controls the rate of change reported via the mA Output.
If mA Output Process Variable is set to Density, and both Density Damping and Added Damping are set to
non-zero values, density damping is applied first, and the added damping calculation is applied to the result
of the first calculation. This value is reported over the mA Output.
4.5.4 Configure Density Cutoff
Density Cutoff specifies the lowest density value that will be reported as measured. All density values below
this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
For most applications, the default setting (0.2 g/cm³) is sufficient. The range is 0.0 g/cm³ to 0.5 g/cm³.
Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density Cutoff, the
volume flow rate is reported as 0. Density Cutoff does not affect gas standard volume measurement. Gas
standard volume values are always calculated from the value configured for Standard Gas Density or polled
value if configured for polled base density.

4.8 Set up concentration measurement
This section guides you through loading and setting up a concentration matrix used for measurement. It does
not cover building a concentration matrix.
The concentration measurement application calculates concentration data from process temperature and
density. Micro Motion provides a set of concentration matrices that provide the reference data for several
standard industry applications and process fluids. If desired, you can build a custom matrix for your process
fluid, or purchase a custom matrix from Micro Motion.
Note
Concentration matrices can be made available on your transmitter either by loading an existing matrix from a
file or by building a new matrix. Up to six matrices can be available on your transmitter, but only one can be
used for measurement at any given time. See the Micro Motion Enhanced Density Application Manual for
detailed information on building a matrix.
Prerequisites
Before you can configure concentration measurement:
• The concentration measurement application must be purchased on your transmitter.
• The concentration matrix you want to use must be available on your transmitter, or it must be available as
a file on your computer.
• You must know the derived variable that your matrix is designed for.
• You must know the density unit used by your matrix.
• You must know the temperature unit used by your matrix.
• The concentration measurement application must be unlocked.
4.8.1 Configure concentration measurement using ProLink III
Procedure
1. Choose Device Tools → Configuration → Process Measurement → Density and set Density Unit to

e) Review the data points for this matrix.
f) Do not change Reference Temperature or Curve Fit Maximum Order.
g) If you changed any matrix data, click Apply.
7. Set up extrapolation alarms.
Each concentration matrix is built for a specific density range and a specific temperature range. If
process density or process temperature goes outside the range, the transmitter will extrapolate
concentration values. However, extrapolation may affect accuracy. Extrapolation alarms are used to
notify the operator that extrapolation is occurring.
a) If necessary, set Matrix Being Configured to the matrix you want to view, and select Change
Matrix.
b) Set Extrapolation Alarm Limit to the point, in percent, at which an extrapolation alarm will be
posted.
c) Enable or disable the high and low limit alarms for temperature and density, as desired, and
select Apply.
Example
If Extrapolation Alarm Limit is set to 5%, High Extrapolation Limit (Temperature) is enabled, and the
matrix is built for a temperature range of 40 °F (4.4 °C) to 80 °F (26.7 °C), an extrapolation alarm will be
posted if process temperature goes above 82 °F (27.8 °C).
8. If you chose RTD, no more configuration is required. Select Apply and exit.
9. If you chose to use a static temperature value, set External Temperature to the value to use, and select
Apply.
10. If you want to use digital communications, select Apply, then perform the necessary host
programming and communications setup to write temperature data to the transmitter at appropriate

4.9 Configure pressure compensation
Pressure compensation adjusts process measurement to compensate for the pressure effect on the sensor.
The pressure effect is the change in the sensor’s sensitivity to flow and density caused by the difference
between the calibration pressure and the process pressure.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific sensor model
can be found in the product data sheet located at www.emerson.com. If you are uncertain about
implementing pressure compensation, contact customer service.
Prerequisites
You will need the flow factor, density factor, and calibration pressure values for your sensor.
• For the flow factor and density factor, see the product data sheet for your sensor.
• For the calibration pressure, see the calibration sheet for your sensor. If the data is unavailable, use 20 PSI.
4.9.1 Configure pressure compensation using ProLink III
Procedure
1. Choose Device Tools → Configuration → Process Measurement → Pressure Compensation.
2. Set Pressure Compensation Status to Enabled.
3. Set Pressure Unit to the appropriate unit.
If you will use an external pressure value, set Pressure Unit to match the pressure unit used by the
external pressure device.
4. Enter Flow Calibration Pressure for your sensor.
The calibration pressure is the pressure at which your sensor was calibrated, and defines the pressure at
which there is no pressure effect. If the data is unavailable, enter 20 PSI.
5. Enter Flow Factor for your sensor.
The flow factor is the percent change in the flow rate per PSI. When entering the value, reverse the
sign.

Example
If the flow factor is 0.000004 % per PSI, enter −0.000004 % per PSI.
6. Enter Density Factor for your sensor.
The density factor is the change in fluid density, in g/cm3/PSI. When entering the value, reverse the
sign.
Example
If the density factor is 0.000006 g/cm3/PSI, enter −0.000006 g/cm3/PSI.
Postrequisites
If you are receiving pressure data over the mA Input, ensure that the mA Input is configured for your
application.

6.1 Configure the mA Output
The mA Output is used to report the configured process variable. The mA Output parameters control how the
process variable is reported.
Your transmitter has two mA Outputs.
Important
Whenever you change an mA Output parameter, verify all other mA Output parameters before returning the
meter to service. In some situations, the transmitter automatically loads a set of stored values, and these
values may not be appropriate for your application.

Use mA Output Process Variable to select the variable that is reported over the mA Output. This variable is
applied automatically to the Frequency Output.
Prerequisites
• If you plan to configure the output to report volume flow, ensure that you have set Volume Flow Type as
desired: Liquid or Gas Standard Volume.
• If you plan to configure an output to report a concentration measurement process variable, ensure that
the concentration measurement application is configured so that the desired variable is available.
• If you are using the HART variables, be aware that changing the configuration of mA Output Process
Variable will change the configuration of the HART Primary Variable (PV) and/or the HART Secondary
Variable (SV).
Procedure
Set mA Output Process Variable as desired.
Default settings are as follows:
• Primary mA Output: Mass Flow Rate
• Secondary mA Output: Density
Postrequisites
If you changed the setting of mA Output Process Variable, verify the settings of Lower Range Value (LRV)
and Upper Range Value (URV).

Configure → Manual Setup → Inputs/Outputs → mA Output X → mA Output Settings → PV/SV URV
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA Output, that is, to
define the relationship between mA Output Process Variable and the mA Output level.
Prerequisites
Ensure that mA Output Process Variable is set to the desired process variable. Each process variable has its
own set of LRV and URV values. When you change the values of LRV and URV, you are configuring values for
the currently assigned mA Output process variable.
Ensure that the measurement unit for the configured process variable has been set as desired.
Note
If you change LRV and URV from the factory default values, and you later change mA Output Process
Variable, LRV and URV will not be reset to the default values. For example, if you set mA Output Process
Variable to Mass Flow Rate and change the LRV and URV, then you set mA Output Process Variable to
Density, and finally you change mA Output Process Variable back to Mass Flow Rate, LRV and URV for Mass
Flow Rate are reset to the values that you configured.
Procedure
Set LRV and URV as desired.
• LRV is the value of mA Output Process Variable represented by an output of 0 or 4 mA. The default value
for LRV depends on the setting of mA Output Process Variable. Enter LRV in the measurement units that
are configured for mA Output Process Variable.
• URV is the value of mA Output Process Variable represented by an output of 20 mA. The default value for
URV depends on the setting of mA Output Process Variable. Enter URV in the measurement units that are
configured for mA Output Process Variable.
Tip
For best performance:
• Set LRV ≥ LSL (lower sensor limit).
• Set URV ≤ USL (upper sensor limit).
• Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span).
Defining URV and LRV within the recommended values for Min Span, LSL, and USL ensures that the resolution
of the mA Output signal is within the range of the bit precision of the D/A converter.
The mA Output uses a range of 4–20 mA or 0–20 mA to represent mA Output Process Variable. Between
LRV and URV, the mA Output is linear with the process variable. If the process variable drops below LRV or
rises above URV, the transmitter posts an output saturation alert.

6.1.4 Configure Added Damping
Display Not available
ProLink III Device Tools → Configuration → I/O → Outputs → mA Output
Field Communicator Configure → Manual Setup → Inputs/Outputs → mA Output 1 → mA Output Settings → PV Added
Added Damping controls the amount of damping that will be applied to the mA Output.
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies
the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end
of the interval, the internal value will reflect 63% of the change in the actual measured value.
Added Damping affects the reporting of mA Output Process Variable through the mA Output only. It does
not affect the reporting of that process variable via any other method (e.g., a Frequency Output or digital
communications), or the value of the process variable used in calculations.
Note
Added Damping is not applied if the mA Output is fixed (for example, during loop testing) or if the mA
Output is reporting a fault. Added Damping is applied while sensor simulation is active.
Procedure
Set Added Damping to the desired value.
The default value is 0.0 seconds. The range is 0.0 to 440 seconds.
Damping

Interaction between mA Output Damping and process variable damping
When mA Output Source is set to a flow rate variable, density, or temperature, mA Output Damping
interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple damping parameters
are applicable, the effect of damping the process variable is calculated first, and the mA Output damping
calculation is applied to the result of that calculation.
Damping interaction
Configuration:
• Flow Damping = 1 second
• mA Output Source = Mass Flow Rate
• mA Output Damping = 2 seconds
Result: A change in the mass flow rate will be reflected in the 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.

Flow Switch is used to indicate that the flow rate (measured by the configured flow variable) has moved past
the configured setpoint, in either direction. The flow switch is implemented with a user-configurable
hysteresis.
Procedure
1. Set Discrete Output Source to Flow Switch, if you have not already done so.
2. Set Discrete Output Source to Velocity Switch, if you have not already done so.
3. Set Flow Switch Variable to the flow variable that you want to use to control the flow switch.
4. Set Flow Switch Setpoint to the value at which the flow switch will be triggered (after Hysteresis is
applied).
• If the flow rate is below this value, the Discrete Output is ON.
• If the flow rate is above this value, the Discrete Output is OFF.
5. Set Hysteresis to the percentage of variation above and below the setpoint that will operate as a
deadband.
Hysteresis defines a range around the setpoint within which the flow switch will not change. The
default is 5%. The valid range is 0.1% to 10%.

this happens, the Discrete Output will turn ON, and remain ON until the flow rate rises above
105 g/sec. At this point it turns OFF and will remain OFF until the flow rate drops below 95 g/sec.

6.3.4 Configure Discrete Output Fault Action
Display Not available
ProLink III Device Tools → Configuration → Fault Processing
Field Communicator Configure → Manual Setup → Inputs/Outputs → Discrete Output → DO Fault Action
Discrete Output Fault Action controls the behavior of the Discrete Output if the transmitter encounters an
internal fault condition.
Note
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement the fault
action until the timeout has elapsed.
CAUTION
Do not use Discrete Output Fault Action as a fault indicator. If you do, you may not be able to distinguish a
fault condition from a normal operating condition. If you want to use the Discrete Output as a fault
indicator, set Discrete Output Source to Fault and set Discrete Output Fault Action to None.
Procedure
Set Discrete Output Fault Action as desired.
The default setting is None.

6.4 Configure the Discrete Input
The Discrete Input is used to initiate one or more transmitter actions from a remote input device. Your
transmitter has one Discrete Input.
The Discrete Input parameters include:
• Discrete Input Action
• Discrete Input Polarity
Important
Whenever you change a Discrete Input parameter, verify all other Discrete Input parameters before returning
the flowmeter to service. In some situations, the transmitter automatically loads a set of stored values, and
these values may not be appropriate for your application.

Display
Field Communicator mA Input LRV: Configure → Manual Setup → Inputs/Outputs → Milliamp Input → mA Input LRV
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the readings received from the
external measurement device, i.e., to define the relationship between mA input Process Variable and the mA
Input level received. Between LRV and URV, the mA Input is linear with the process variable. If the process
variable drops below LRV or rises above URV, the transmitter posts an external input error.
Prerequisites
Verify that you have set the measurement units for the pressure or temperature to match the units
configured at the external measurement device. For example, if the external measurement device is set to
send pressure data in PSI, you must set the pressure measurement units to be PSI at your transmitter.

6.6 Configure events
An event occurs when the real-time value of a user-specified process variable moves past a user-defined
setpoint. Events are used to provide notification of process changes or to perform specific transmitter actions
if a process change occurs.
Your transmitter supports two event models:
• Basic event model
• Enhanced event model
6.6.1 Configure a basic event
Display Not available
ProLink III Device Tools → Configuration → Events → Basic Events

A basic event is used to provide notification of process changes. A basic event occurs (is ON) if the real-time
value of a user-specified process variable moves above (Active High) or below (Active Low) a user-defined
setpoint. You can define up to two basic events. Event status can be queried via digital communications, and
a Discrete Output can be configured to report event status.
Procedure
1. Select the event that you want to configure.
2. Specify Type.
Option
Active High x > A
Active Low x < A
3. Assign a process variable to the event.
4. Set a value for Setpoint A.
5. Optional: Configure a Discrete Output to switch states in response to the event status.
Description
The event occurs when the value of the assigned process variable (x) is greater than the
setpoint (Setpoint A), endpoint not included.
The event occurs when the value of the assigned process variable (x) is less than the
setpoint (Setpoint A), endpoint not included.

An enhanced event is used to provide notification of process changes and, optionally, to perform specific
transmitter actions if the event occurs. An enhanced event occurs (is ON) if the real-time value of a userspecified process variable moves above (HI) or below (LO) a user-defined setpoint, or in range (IN) or out of
range (OUT) with respect to two user-defined setpoints. You can define up to five enhanced events.
Procedure
1. Select the event that you want to configure.
2. Specify Event Type.
Option Description
HI x > A
The event occurs when the value of the assigned process variable (x) is greater
than the setpoint (Setpoint A), endpoint not included.
LO x < A
The event occurs when the value of the assigned process variable (x) is less than
the setpoint (Setpoint A), endpoint not included.
IN A ≤ x ≤ B
The event occurs when the value of the assigned process variable (x) is in range,
that is, between Setpoint A and Setpoint B, endpoints included.
OUT x ≤ A or x ≥ B
The event occurs when the value of the assigned process variable (x) is out of
range, that is, less than Setpoint A or greater than Setpoint B, endpoints
included.
3. Assign a process variable to the event.
4. Set values for the required setpoints.
• For HI and LO events, set Setpoint A.
• For IN and OUT events, set Setpoint A and Setpoint B.
5. Optional: Configure a Discrete Output to switch states in response to the event status.
6.7 Configure digital communications
The digital communications parameters control how the transmitter will communicate using digital
communications.
Your transmitter supports the following types of digital communications:
• HART/Bell 202 over the primary mA terminals
• HART/RS-485 over the RS-485 terminals
• Modbus/RS-485 over the RS-485 terminals
• Modbus RTU via the service port
Note
The service port responds automatically to a wide range of connection requests. It is not configurable.

6.7.1 Configure HART/Bell 202 communications
HART/Bell 202 communications parameters support HART communications with the transmitter's primary
mA terminals over a HART/Bell 202 network.
Configure basic HART parameters
Basic HART parameters include the HART address, HART tags, and the operation of the primary mA Output.
HART/Bell 202 communications parameters support HART communication with the transmitter's primary mA
terminals over a HART/Bell 202 network. The HART/Bell 202 communications parameters include:
• HART Address (Polling Address)
• mA Output Action
• Burst Parameters (optional)
• HART Variables (optional)
Procedure
1. Set HART Address to a value that is unique on your network.
• Default: 0
• Range: 0 to 15
Tip
• The default address is typically used unless you are in a multidrop environment.
• Devices using HART protocol to communicate with the transmitter may use either HART Address or
HART Tag (Software Tag) to identify the transmitter. Configure either or both, as required by your
other HART devices.
2. Ensure that mA Output Action is configured appropriately.
Option
Enabled (Live) The primary mA Output reports process data as configured.
Disabled (Fixed) The primary mA Output is fixed at 4 mA and does not report process data.
Description
Important
If you use ProLink III to set HART Address to 0, the program automatically enables mA Output Action.
If you use ProLink III to set HART Address to any other value, the program automatically disables mA
Output Action. This is designed to make it easier to configure the transmitter for legacy behavior.
Always verify mA Output Action after setting HART Address.
