Topics covered in this chapter:
Power up the transmitter
•
Check flowmeter status
•
Make a startup connection to the transmitter
•
Characterize the flowmeter (if required)
•
Verify mass flow measurement
•
Verify the zero
•
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1. Ensure that all transmitter and sensor covers and seals are closed.
Quick start
2.2
CAUTION!
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. During this period,
Alarm 009 is active. The diagnostic routines should complete in approximately
30 seconds. For transmitters with a display, the status LED will turn green and begin
to flash when the startup diagnostics are complete. If the status LED exhibits
different behavior, an alarm condition is present.
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 is 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.
Check flowmeter status
Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.
Configuration and Use Manual 5
Quick start
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, Alarm A009 is active.
This alarm should clear automatically when the power-up sequence is complete.
2. Check the status LED on the transmitter.
Transmitter status reported by status LEDTable 2-1:

and have been acknowledged.
A low-severity alarm condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or process measurement. If you choose, you can identify and resolve the alarm condition.
A low-severity alarm condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or process measurement. If you choose, you can identify and resolve the alarm condition. You may
also acknowledge the alarm.
A high-severity alarm condition affects measurement accuracy and output behavior. Resolve the alarm condition before continuing.
Postrequisites
For information on viewing the list of active alarms, see Section 8.3.
For information on individual alarms and suggested resolutions, see Section 10.2.
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.
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.

Postrequisites
(Optional) Change the communications parameters to site-specific values.
To change the communications parameters using ProLink II:
• To change the protocol, baud rate, parity, or stop bits, choose ProLink > Configuration >
RS-485.
• To change the address, choose ProLink > Configuration > Device.
To change the communications parameters using the Field Communicator, choose On-Line
Menu > Configure > Manual Setup > Inputs/Outputs > Communications.
Important
If you are changing communications parameters for the connection type that you are using, you will
lose the connection when you write the parameters to the transmitter. Reconnect using the new
parameters.
2.4 Characterize the flowmeter (if required)
Display

Field Communicator Configure > Manual Setup > Characterize
Overview
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.
Not available
• Straight-tube (T-Series)
• Curved-tube (all sensors except T-Series)
Configuration and Use Manual 7
Quick start
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.
• For curved-tube sensors, set Flow Cal (Flow Calibration Factor).
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 4character FT value. They are provided on the sensor tag.
Both values contain decimal points. During characterization, these may be entered as two
values or as a single 10-character string. 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.
If your sensor tag shows a concatenated Flowcal or FCF value and you need to enter the FCF
and the FT values separately, split the concatenated value:
• FCF = The first 6 characters, including the decimal point
• FT = The last 4 characters, including the decimal point
Configuration and Use Manual 9
Quick start
Example: Concatenating FCF and FT
FCF = x.xxxx
FT = y.yy
Flow calibration parameter: x.xxxxy.yy
Example: Splitting the concatenated Flowcal or FCF value
Flow calibration parameter: x.xxxxy.yy
FCF = x.xxxx
FT = y.yy
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 0.998 g/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 the sample tag, this
value is shown as 12500.
• For K2, enter the second 5 digits of the density calibration factor. In the sample tag,
this value is shown as 14286.
If your sensor does not show an FD value, contact Micro Motion customer service.
If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density
calibration factor. In the sample tag, this value is shown as 4.44.
Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use
any available method.
• Read the value for Mass Flow Rate on the transmitter display.
• Connect to the transmitter with ProLink II and read the value for Mass Flow Rate in the
Process Variables window (ProLink > Process Variables).
• Connect to the transmitter with the Field Communicator and read the value for Mass
Flow Rate in the Process Variables menu (On-Line Menu > Overview > Primary Purpose
Variables).
10 Micro Motion® 9739 MVD Transmitters
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues. See
Section 10.3.
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.
2.6.1 Verify the zero using ProLink II
Quick start
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.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless
one of the following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Prerequisites
ProLink II v2.94 or later
Important
Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem,
then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a lowseverity alarm is active.
Procedure
1. Prepare the flowmeter:
a. Allow the flowmeter to warm up for at least 20 minutes after applying power.
b. Run the process fluid through the sensor until the sensor temperature reaches
the normal process operating temperature.
c. Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
Configuration and Use Manual 11
Quick start
d. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
2. Choose ProLink > Calibration > Zero Verification and Calibration > Verify Zero and wait until
the procedure completes.
3. 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. Repeat the zero verification procedure.
d. If it fails again, zero the flowmeter.
For instructions on zeroing the flowmeter, see Zero the flowmeter.
Postrequisites
Restore normal flow through the sensor by opening the valves.
2.6.2 Terminology used with zero verification and zero
calibration
Terminology used with zero verification and zero calibrationTable 2-2:
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 proce-
dure. 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 ap-
plied. 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.

Overview
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
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.
The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).
1. Set Base Mass Unit to Pounds (lb).
2. Set Base Time Unit to Seconds (sec).
3. Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
Configuration and Use Manual 23

4.1.2 Configure Flow Damping
Display
ProLink II ProLink > Configuration > Flow > Flow Damp
Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping
Not available
Overview
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 reported process variable. At the end of the interval, the reported process variable
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 range is 0 to 10.24 seconds.
Tips
• 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.
• Micro Motion recommends using the default value of 0.04 seconds.
The value you enter is automaticaly rounded down to the nearest valid value. The valid
values for Flow Damping are: 0, 0.04, 0.08, 0.16, ... 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.
24 Micro Motion® 9739 MVD Transmitters
Interaction between Flow Damping and Added Damping
In some circumstances, both Flow Damping and Added Damping are applied to the reported
mass flow value.
Flow Damping controls the rate of change in flow process variables. Added 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 Added 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
Configure process measurement
Display
ProLink II ProLink > Configuration > Flow > Mass Flow Cutoff
Field Communicator Configure > Manual Setup > Measurements > Flow > Mass Flow Cutoff
Overview
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 setting is 0.05% of the sensor's rated maximum flow rate or a
value below the highest expected flow rate. Do not set Mass Flow Cutoff to 0.0 g/sec.
Not available
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.
Interaction between Mass Flow Cutoff and AO Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as
measured. AO 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).
AO Cutoff affects only mass flow values reported via the mA output.
Configuration and Use Manual 25
Configure process measurement
Example: Cutoff interaction with AO Cutoff lower than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• AO 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.
Example: Cutoff interaction with AO Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• AO Cutoff: 15 g/sec
• Mass Flow Cutoff: 10 g/sec
4.2
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.

Interaction between Volume Flow Cutoff and AO Cutoff
Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will
report as measured. AO Cutoff defines the lowest flow rate that will be reported via the mA
output. If mA Output Process Variable is set to Volume Flow Rate, the volume flow rate reported
via the mA output is controlled by the higher of the two cutoff values.
Volume Flow Cutoff affects both the volume flow values reported via the outputs and the
volume flow values used in other transmitter behavior (e.g., events defined on the volume
flow).
AO Cutoff affects only flow values reported via the mA output.
Example: Cutoff interaction with AO Cutoff lower than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 10 l/sec
• Volume Flow Cutoff: 15 l/sec
Result: If the volume flow rate drops below 15 l/sec, volume flow will be reported as 0, and
0 will be used in all internal processing.
Example: Cutoff interaction with AO Cutoff higher than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 15 l/sec
• Volume Flow Cutoff: 10 l/sec
Result:
• If the volume flow rate drops below 15 l/sec but not below 10 l/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 volume flow rate drops below 10 l/sec, both outputs will report zero flow, and
0 will be used in all internal processing.

Overview
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 Gas Standard Volume Unit.
Base Gas Standard Volume Unit is the existing gas standard volume 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 Gas Standard Volume Flow Conversion Factor as follows:
a. x base units = y special units
b. Gas Standard Volume Flow Conversion Factor = x/y
4. Enter the Gas Standard Volume Flow Conversion Factor.
5. Set Gas Standard Volume Flow Label to the name you want to use for the gas standard
volume flow unit.
6. Set Gas Standard Volume Total Label to the name you want to use for the gas standard
volume total and gas standard volume inventory unit.
The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for gas standard volume flow
You want to measure gas standard volume flow in thousands of standard cubic feet per
minute.
1. Set Base Gas Standard Volume Unit to SCFM.
2. Set Base Time Unit to minutes (min).
3. Calculate the conversion factor:
a. 1 thousands of standard cubic feet per minute = 1000 cubic feet per minute
b. Gas Standard Volume Flow Conversion Factor = 1/1000 = 0.001
4. Set Gas Standard Volume Flow Conversion Factor to 0.001.
5. Set Gas Standard Volume Flow Label to KSCFM.
6. Set Gas Standard Volume Total Label to KSCF.

4.3.4 Configure Gas Standard Volume Flow Cutoff
Display
ProLink II ProLink > Configuration > Flow > Std Gas Vol Flow Cutoff
Field Communicator Configure > Manual Setup > Measurements > Gas Standard Volume > GSV Cutoff
Overview
Gas Standard Volume Flow Cutoff specifies the lowest gas standard volume flow rate that will
reported as measured. All gas standard volume flow rates below this cutoff will be
reported as 0.
Procedure
Set Gas Standard Volume Flow Cutoff to the value you want to use.
The default value for Gas Standard Volume Flow Cutoff is 0.0. The lower limit is 0.0. There is no
upper limit.
Not available
Interaction between Gas Standard Volume Flow Cutoff and AO Cutoff
Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that the
transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be
reported via the mA output. If mA Output Process Variable is set to Gas Standard Volume Flow
Rate, the volume flow rate reported via the mA output is controlled by the higher of the
two cutoff values.
Gas Standard Volume Flow Cutoff affects both the gas standard volume flow values reported
via outputs and the gas standard volume flow values used in other transmitter behavior
(e.g., events defined on gas standard volume flow).
AO Cutoff affects only flow values reported via the mA output.
Example: Cutoff interaction with AO Cutoff lower than Gas Standard Volume Flow
Cutoff
Configuration:
• mA Output Process Variable for the primary mA output: Gas Standard Volume Flow Rate
• Frequency Output Process Variable: Gas Standard Volume Flow Rate
• AO Cutoff for the primary mA output: 10 SLPM (standard liters per minute)
• Gas Standard Volume Flow Cutoff: 15 SLPM
Result: If the gas standard volume flow rate drops below 15 SLPM, the volume flow will be
reported as 0, and 0 will be used in all internal processing.

Flow Direction is defined with respect to the flow arrow on the sensor:
• Forward flow (positive flow) moves in the direction of the flow arrow on the sensor.
• Reverse flow (negative flow) moves in the direction opposite to the flow arrow on
the sensor.
Tip
Micro Motion sensors are bidirectional. Measurement accuracy is not affected by actual flow
direction or the setting of the Flow Direction parameter.

Configure > Manual Setup > Measurements > Density > Slug Duration
Overview
The slug flow parameters control how the transmitter detects and reports two-phase flow
(gas in a liquid process or liquid in a gas process).
Procedure
1. Set Slug Low Limit to the lowest density value that is considered normal in your
process.
Values below this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the lowest density value in the normal range of your
process.
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of slug flow alarms that are not significant to your process, set Slug Low Limit
slightly below your expected lowest process density.
You must enter Slug Low Limit in g/cm3, even if you configured another unit for
density measurement.
The default value for Slug Low Limit is 0.0 g/cm3. The range is 0.0 to 10.0 g/cm3.
2. Set Slug High Limit to the highest density value that is considered normal in your
process.
Values above this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the highest density value in the normal range of your
process.
Tip
To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug
High Limit slightly above your expected highest process density.
You must enter Slug High Limit in g/cm3, even if you configured another unit for
density measurement.
44 Micro Motion® 9739 MVD Transmitters
Configure process measurement
The default value for Slug High Limit is 5.0 g/cm3. The range is 0.0 to 10.0 g/cm3.
3. Set Slug Duration to the number of seconds that the transmitter will wait for a slug
flow condition to clear before performing the configured slug flow action.
The default value for Slug Duration is 0.0 seconds. The range is 0.0 to 60.0 seconds.
Slug flow detection and reporting
Slug flow is typically used as an indicator of two-phase flow (gas in a liquid process or liquid
in a gas process). Two-phase flow can cause a variety of process control issues. By
configuring the slug flow parameters appropriately for your application, you can detect
process conditions that require correction.
Tip
To decrease the occurrence of slug flow alarms, lower Slug Low Limit or raise Slug High Limit.
A slug flow condition occurs whenever the measured density goes below Slug Low Limit or
above Slug High Limit. If this occurs:
4.5.3
• A slug flow alarm is posted to the active alarm log.
• All outputs that are configured to represent flow rate hold their last “pre-slug flow”
value for the configured Slug Duration.
If the slug flow condition clears before Slug Duration expires:
• Outputs that represent flow rate revert to reporting actual flow.
• The slug flow alarm is deactivated, but remains in the active alarm log until it is
acknowledged.
If the slug flow condition does not clear before Slug Duration expires, the outputs that
represent flow rate report a flow rate of 0.
If Slug Duration is set to 0.0 seconds, the outputs that represent flow rate will report a flow
rate of 0 as soon as slug flow is detected.
Configure Density Damping
Display
ProLink II ProLink > Configuration > Density > Density Damping
Field Communicator Configure > Manual Setup > Measurements > Density > Density Damping
Not available
Overview
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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value.
Configuration and Use Manual 45
Configure process measurement
Procedure
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. The range is 0 to 10.24 seconds.
Tips
• 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 automaticaly rounded down to the nearest valid value. The valid
values for Density Damping are: 0, 0.04, 0.08, 0.16, ... 10.24.
4.5.4
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
In some circumstances, both Density Damping and Added Damping are applied to the reported
density value.
Density Damping controls the rate of change in the density process variable. 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.

Procedure
Set Density Cutoff to the value you want to use.
The default value for Density Cutoff is 0.2 g/cm3. 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.
4.6 Configure temperature measurement

Procedure

The default value is 4.8 seconds. The range is 0.0 to 76.8 seconds.
Tips
• 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

The value you enter is automaticaly rounded down to the nearest valid value. Valid values
for Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 76.8.
Effect of Temperature Damping on process measurement
Temperature Damping affects the response speed for temperature compensation with
fluctuating temperatures. Temperature compensation adjusts the process measurement
to compensate for the effect of temperature on the sensor tube.
Temperature Damping affects petroleum measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for petroleum measurement, Temperature Damping does not
affect petroleum measurement process variables.
Temperature Damping affects concentration measurement process variables only if the
transmitter is configured to use temperature data from the sensor. If an external
temperature value is used for concentration measurement, Temperature Damping does not
affect concentration measurement process variables.
4.7 Configure the petroleum measurement application
The petroleum measurement application enables Correction for the effect of Temperature
on the volume of Liquids (CTL), by calculating and applying a Volume Correction Factor

4.8 Configure the concentration measurement application
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.
More information about the concentration measurement application is available in the
following manual: Micro Motion Enhanced Density Application: Theory, Configuration, and
Use.
Note
The concentration measurement application is also known as the enhanced density application.
4.8.1 Configure concentration measurement using ProLink II
This task guides you through loading and setting up a concentration matrix to use for
measurement. It does not cover building a concentration matrix.
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 Micro Motion Enhanced Density
Application: Theory, Configuration, and Use for detailed information on building a matrix.
Prerequisites
Before you can configure concentration measurement:
• The concentration measurement application must be enabled 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.
Procedure

Important
• All concentration matrices on your transmitter must use the same derived variable. If you
are using one of the standard matrices from Micro Motion, set Derived Variable to Mass Conc
(Density). If you are using a custom matrix, see the reference information for your matrix.
• If you change the setting of Derived Variable, all existing concentration matrices will be
deleted from transmitter memory. Set Derived Variable before loading concentration
matrices.
a. In Curve Specific Config, set Curve Configured to the location to which the matrix
will be loaded.
b. Click Load this curve from a file, navigate to the matrix file on your PC, and load it.
c. Repeat until all required matrices are loaded.
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. In Curve Specific Config, set Curve Configured to the matrix that you want to
configure.
b. Set Alarm Limit to the point, in percent, at which an extrapolation alarm will be
posted.
Example: If Alarm Limit is set to 5%, Enable Temp High is checked, and the matrix is built
for a temperature range of 40 °F to 80 °F, an extrapolation alarm will be posted if
process temperature goes above 82 °F

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.

Overview
Update Rate controls the rate at which process data is polled and process variables are
calculated. Update Rate = Special produces faster and “noisier” response to changes in the
process. Do not use Special mode unless required by your application.
Prerequisites
Before setting Update Rate to Special:
• Check the effects of Special mode on specific process variables.
• Contact Micro Motion.
Procedure
Set Update Rate as desired.
Option
Normal
Special
Description
All process data is polled at the rate of 20 times per second (20 Hz).
All process variables are calculated at 20 Hz.
This option is appropriate for most applications.
A single, user-specified process variable is polled at the rate of 100 times per second
(100 Hz). Other process data is polled at 6.25 Hz). Some process, diagnostic, and calibration data is not polled.
All available process variables are calculated at 100 Hz.
Use this option only if required by your application.
If you change Update Rate, the settings for Flow Damping, Density Damping, and Temperature
Damping are automatically adjusted.
Effects of Update Rate = Special
Incompatible features and functions
Special mode is not compatible with the following features and functions:
• Enhanced events. Use basic events instead.
• All calibration procedures.
• Zero verification.
• Restoring the factory zero or the prior zero.
If required, you can switch to Normal mode, perform the desired procedures, and then
return to Special mode.

Configure device options and preferences
Restriction
Fault Timeout is applied only to the following alarms (listed by Status Alarm Code): A003, A004, A005,
A008, A016, A017, A033. For all other alarms, fault actions are performed as soon as the alarm is
detected.
Procedure
Set Fault Timeout as desired.
The default value is 0 seconds. The range is 0 to 60 seconds.
If you set Fault Timeout to 0, fault actions are performed as soon as the alarm condition is
detected.
The fault timeout period begins when the transmitter detects an alarm condition. During
the fault timeout period, the transmitter continues to report its last valid measurements.
If the fault timeout period expires while the alarm is still active, the fault actions are
performed. If the alarm condition clears before the fault timeout expires, no fault actions
are performed.

Overview
Use mA Output Process Variable to select the variable that is reported over the mA 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
Options for mA Output Process Variable

Configure > Manual Setup > Inputs/Outputs > mA Output X > mA Output Settings > PV/SV URV
Overview
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.
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.
Tips
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 range of the bit precision of the D/A converter.
86 Micro Motion® 9739 MVD Transmitters
Integrate the meter with the control system
Note
You can set URV below LRV. For example, you can set URV to 50 and LRV to 100.
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
alarm.
Default values for Lower Range Value (LRV) and Upper Range Value (URV)
Each option for mA Output Process Variable has its own LRV and URV. If you change the
configuration of mA Output Process Variable, the corresponding LRV and URV are loaded and
used.

Overview
AO Cutoff (Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or
gas standard volume flow rate that will be reported through the mA output. Any flow rates
below AO Cutoff will be reported as 0.
Restriction
AO Cutoff is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or Gas
Standard Volume Flow Rate. If mA Output Process Variable is set to a different process variable, AO Cutoff is
not configurable, and the transmitter does not implement the AO cutoff function.

service before changing AO Cutoff.
Interaction between AO Cutoff and process variable cutoffs
When mA Output Process Variable is set to a flow variable (for example, mass flow rate or
volume flow rate), AO Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The
transmitter puts the cutoff into effect at the highest flow rate at which a cutoff is
applicable.
Example: Cutoff interaction
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO Cutoff = 10 g/sec
• Mass Flow Cutoff = 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will
report zero flow.
Example: Cutoff interaction
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO 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.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.

Configure > Manual Setup > Inputs/Outputs > mA Output 2 > mA Output Settings > PV Added Damping
Overview
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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value. Added Damping controls the
amount of damping that will be applied to the mA output. It 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., the frequency output or digital
communications), or the value of the process variable used in calculations.
Integrate the meter with the control system
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.
When you specify a value for Added Damping, the transmitter automatically rounds the value
down to the nearest valid value.
Valid values for Added DampingTable 6-3:
Valid values for Added Damping
0.0, 0.1, 0.3, 0.75, 1.6, 3.3, 6.5, 13.5, 27.5, 55, 110, 220, 440
Interaction between Added Damping and process variable damping
When mA Output Process Variable is set to a flow variable, density, or temperature, Added
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 added damping calculation is applied to the result of that
calculation.
Configuration and Use Manual 89
Integrate the meter with the control system
Example: Damping interaction
Configuration:
• Flow Damping = 1 second
• mA Output Process Variable = Mass Flow Rate
• Added 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.

Overview
mA Output Fault Action controls the behavior of the mA output if the transmitter encounters
an internal fault condition.
Note
For some faults only: If Last Measured Value Timeout is set to a non-zero value, the transmitter will not
implement the fault action until the timeout has elapsed.
Procedure
1. Set mA Output Fault Action to the desired value.
The default setting is Downscale.
2. If you set mA Output Fault Action to Upscale or Downscale, set mA Output Fault Level as
desired.

CAUTION!
If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action to None. If you do not, the output will not report actual process data,
and this may result in measurement errors or unintended consequences for your process.
Restriction
If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action to None. If you try to do this, the transmitter will not accept the configuration.

Configure the frequency output
The frequency output is used to report a process variable. The frequency output
parameters control how the process variable is reported.
The frequency output parameters include:
Frequency Output Process Variable
•
Frequency Output Polarity
•
Frequency Output Scaling Method
•
Frequency Output Maximum Pulse Width
•
• Frequency Output Fault Action and Frequency Output Fault Value
Frequency Output Power Source
•
Configuration and Use Manual 91

Important
Whenever you change a frequency output parameter, verify all other frequency output 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.
