2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks or for process measurement.
Procedure
1.
WARNING
If the transmitter is in a hazardous area, do not remove the housing cover while the transmitter is powered up. Failure to follow these instructions can cause an explosion resulting in injury or death.
Ensure that all transmitter and sensor covers and seals are closed.
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 and begin to flash 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 ten 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 ten 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.

2.4 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.
Menu → Operations → Process Variable Values
• 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 a field communicator and read the value for Mass Flow Rate .
Online → Overview → 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.
For information about modifying these values, refer to Configure mass flow measurement
.
2.5 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.
Do not verify the zero or zero the meter if a high-severity alert is active. Correct the problem, then verify the zero or zero the meter. You may verify the zero or zero the meter if a low-severity alert is active.
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.

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 .

Device Tools → Configuration → Process Measurement → Flow
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 range depends on the core processor type and the setting of Update
Rate , as shown in the following table.
Update Rate setting

Damping range
0 to 51.2 seconds
0 to 40.96 seconds
The value you enter is automatically rounded off to the nearest valid value. For example, if the damping is currently set to 0.8 seconds, any value entered up to 1.2 seconds will be rounded down to 0.8 seconds, and any value entered from 1.21 to 1.59 seconds will be rounded up to 1.6 seconds.

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 through 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
ProLink III
Field Communicator
Not available
Device Tools → Configuration → Process Measurement → Flow
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. Do not leave Mass Flow Cutoff at 0.0 g/sec.
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 through mA Output. If mA Output
Process Variable is set to Mass Flow Rate, the mass flow rate reported through 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 through mA Output.

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 Volume Unit .
Base Volume Unit is the existing 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 Volume Flow Conversion Factor as follows: a) x base units = y special units b) Volume Flow Conversion Factor = x ÷ y
4. Enter Volume Flow Conversion Factor .
The original volume flow rate value is divided by this conversion factor.
5. Set Volume Flow Label to the name you want to use for the volume flow unit.

Volume Flow Cutoff specifies the lowest volume flow rate that will be reported as measured. All volume flow rates below this cutoff are reported as 0.
Procedure
Set Volume Flow Cutoff to the value you want to use.
The default value for Volume Flow Cutoff is 0.0 l/sec (liters per second). The lower limit is 0. Leaving the volume flow cutoff at 0 is not recommended.
Interaction between Volume Flow Cutoff and mAO Cutoff
Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will report as measured.
mAO Cutoff defines the lowest flow rate that will be reported through mA Output. If mA Output Process
Variable is set to Volume Flow Rate, the volume flow rate reported through 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).
mAO Cutoff affects only flow values reported through mA Output.
Example: Cutoff interaction with mAO 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 mAO 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.

Interaction between Gas Standard Volume Flow Cutoff and mA Output
Cutoff
Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that the transmitter will report as measured.
mA Output Cutoff defines the lowest flow rate that will be reported through mA Output.
If mA Output Process Variable is set to Gas Standard Volume Flow Rate, the volume flow rate reported through 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 through outputs and the gas standard volume flow values used in other transmitter behavior (for example, events defined on gas standard volume flow).
mA Output Cutoff affects only flow values reported through mA Output.
Example: Cutoff interaction with mA Output 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
• mA Output 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.
Example: Cutoff interaction with mA Output Cutoff higher than Gas Standard Volume Flow Cutoff
Configuration:

• Frequency Output Process Variable : Gas Standard Volume Flow Rate
• mA Output Cutoff for the primary mA Output: 15 SLPM (standard liters per minute)
• Gas Standard Volume Flow Cutoff : 10 SLPM
Result:
• If the gas standard volume flow rate drops below 15 SLPM but not below 10 SLPM:
— The primary 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 gas standard volume flow rate drops below 10 SLPM, 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.

You must enter Two-Phase Flow Low Limit in g/cm ³ , even if you configured another unit for density measurement.
The default value for Two-Phase Flow Low Limit is 0.0 g/cm ³ . The range is 0.0 to 10.0 g/cm ³ .
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/cm ³ , even if you configured another unit for density measurement.
The default value for Two-Phase Flow High Limit is 5.0 g/cm ³ . The range is 0.0 to 10.0 g/cm ³ .
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.

Device Tools → Configuration → Process Measurement → Density

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.
Tip
Density damping affects all process variables that are calculated from line density.
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
Normal
Special
Damping range
0 to 51.2 seconds
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.

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/cm ³ ) is sufficient. The range is 0.0 g/cm ³ to 0.5 g/cm ³ .
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 6 matrices can be available on your transmitter, but only 1 can be used for measurement at any given time. For detailed information on building a matrix, see the Micro Motion
Enhanced Density Application Manual .

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 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/cm 3 sign.

Device Tools → Configuration → I/O → Channels
Configure → Manual Setup → Inputs/Outputs → Channels → Channel B
Configure → Manual Setup → Inputs/Outputs → Channels → Channel C
You can configure the channels on your transmitter to operate in several ways. The channel configuration must match the wiring at the transmitter terminals.
Prerequisites
To avoid causing process errors:
• Configure the channels before configuring the outputs.
• Before changing the channel configuration, ensure that all control loops affected by the channel are under manual control.
Important
Before configuring a channel to operate as a Discrete Input, check the status of the remote input device and the actions assigned to the Discrete Input. If the Discrete Input is ON, all actions assigned to the Discrete
Input will be performed when the new channel configuration is implemented. If this is not acceptable, change the state of the remote device or wait to configure the channel as a Discrete Input until an appropriate time.
Note
Channel A always operates as an internally-powered mA Output. If Channel B is configured as an mA Output, it is internally powered.
Important
If you need both a Frequency Output and a Discrete Output, you must first configure Channel B as the
Frequency Output, then configure Channel C as the Discrete Output. Other combinations are invalid and will be rejected by the transmitter.
Procedure
1. Set Channel B as desired.

Description
The channel is powered by the transmitter.
The channel is powered by an external power source.
Postrequisites
For each channel that you configured, perform or verify the corresponding input or output configuration.
When the configuration of a channel is changed, the channel’s behavior will be controlled by the configuration that is stored for the selected input or output type, and the stored configuration may not be appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic control.
6.2 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 may have one or two mA Outputs:
• Channel A is always an mA Output (the primary mA Output).
• Channel B can be configured as an mA Output (the secondary mA Output).
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. The mA and
Frequency Outputs are configured independently. You can assign one process variable to the mA Output and a different process variable 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).
• If you have configured Display Variable 1 to track mA Output Process Variable , be aware that changing the configuration of mA Output Process Variable will change the contents of Display Variable 1 .
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).
Options for mA Output Process Variable

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.

MMI-20019053
Note
For transmitter software v5.0 and later, if you change LRV and URV from the factory default values, and you later change mA Output Process Variable , LRV and URV will not 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 reset to the values that you configured. In earlier versions of the transmitter software, LRV and URV reset to the factory default values.
Procedure
Set LRV and URV as desired.
• LRV is the value of mA Output Process Variable represented by an output of 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 .
The mA Output uses a range of 4–20 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.
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.

Cutoff
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.
Procedure
Set AO Cutoff as desired.
The default values for AO Cutoff are as follows:
• Primary mA Output: 0.0 g/sec
• Secondary mA Output: Not-A-Number
Tip
For most applications, the default value of AO Cutoff should be used. Contact customer 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.

• 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.

Damping
• Configure → Manual Setup → Inputs/Outputs → mA Output 2 → mA Output Settings → SV Added
Damping
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.
When you specify a value for Added Damping , the transmitter automatically rounds the value down to the nearest valid value.
Note
Added Damping values are affected by the setting of Update Rate and 100 Hz Variable .

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.
Example: 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.

6.3 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. Your transmitter may have zero, one, or two Frequency Outputs, depending on the configuration of Channels B and C. If both Channels B and C are configured as Frequency Outputs, they are electrically isolated but not independent. You cannot configure them separately.
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.

Description
Frequency calculated from flow rate
A user-specified number of pulses represents one flow unit
A pulse represents a user-specified number of flow units
2. Set additional required parameters.
• If you set Frequency Output Scaling Method to Frequency=Flow, set Rate Factor and Frequency
Factor .
• If you set Frequency Output Scaling Method to Pulses/Unit, define the number of pulses that will represent one flow unit.
• If you set Frequency Output Scaling Method to Units/Pulse, define the number of units that each pulse will indicate.
For all scaling methods, the transmitter puts out a fixed number of pulses per unit, and at the same time, the Frequency Output signal varies in proportion to flowrate.
Calculate frequency from flow rate
The Frequency=Flow option is used to customize the Frequency Output for your application when you do not know appropriate values for Units/Pulse or Pulses/Unit.
If you specify Frequency=Flow, you must provide values for Rate Factor and Frequency Factor :
Rate Factor The maximum flow rate that you want the Frequency Output to report.
Frequency Factor A value calculated as follows:
× N where:
T Factor to convert selected time base to seconds
N Number of pulses per flow unit, as configured in the receiving device
The resulting Frequency Factor must be within the range of the Frequency Output 0 to 10,000 Hz:
• If Frequency Factor is less than 1 Hz, reconfigure the receiving device for a higher pulses/unit setting.
• If Frequency Factor is greater than 10,000 Hz, reconfigure the receiving device for a lower pulses/unit setting.

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 Flow Switch Variable to the flow variable that you want to use to control the flow switch.
3. 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.
4. 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%.
Example
If Flow Switch Setpoint = 100 g/sec and Hysteresis = 5% , and the first measured flow rate is above
100 g/sec, the Discrete Output is OFF. It will remain OFF unless the flow rate drops below 95 g/sec. If 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.

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)
Disabled (Fixed)
Description
The primary mA Output reports process data as configured.
The primary mA Output is fixed at 4 mA and does not report process data.
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 .

Burst mode is a mode of communication during which the transmitter regularly broadcasts HART digital information over the primary mA Output. The burst parameters control the information that is broadcast when burst mode is enabled.
Tip
In typical installations, burst mode is disabled. Enable burst mode only if you are using a HART Triloop.
Procedure
1. Enable Burst Mode .
2. Set Burst Mode Output as desired.

The transmitter sends the primary variable (PV) in the configured measurement units in each burst (e.g.,
14.0 g/sec, 13.5 g/sec, 12.0 g/sec.
The transmitter sends the PV’s percent of range and the
PV’s actual mA level in each burst (e.g., 25%, 11.0 mA.
The transmitter sends PV, SV, TV, and QV values in measurement units and the PV’s actual milliamp reading in each burst (e.g., 50 g/sec, 23 °C, 50 g/sec, 0.0023 g/cm3,
11.8 mA.
The transmitter sends four user-specified process variables in each burst.
3. Ensure that the burst output variables are set appropriately.
• If you set Burst Mode Output to send four user-specified variables, set the four process variables to be sent in each burst.
• If you set Burst Mode Output to any other option, ensure that the HART variables are set as desired.

8. When you have finished testing or tuning, disable sensor simulation.
7.1.1 Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create the test conditions in your process. When sensor simulation is enabled, the transmitter reports the simulated values for mass flow, density, and temperature, and takes all appropriate actions. For example, the transmitter might apply a cutoff, activate an event, or post an alert.
When sensor simulation is enabled, the simulated values are stored in the same memory locations used for process data from the sensor. The simulated values are then used throughout transmitter functioning. For example, sensor simulation will affect:
• All mass flow rate, temperature, and density values displayed or reported via outputs or digital communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and volume inventories
• All mass, temperature, density, or volume values logged to Data Logger
Sensor simulation does not affect any diagnostic values.
Unlike actual mass flow rate and density values, the simulated values are not temperature-compensated
(adjusted for the effect of temperature on the sensor’s flow tubes).

8 Set up the Weights & Measures application
Information in this chapter is applicable only if your transmitter was ordered with the Weights & Measures application.
8.1 Weights & Measures application
The Weights & Measures application is used to provide process data that is legal for custody transfer applications when an approved method is used to read or obtain the measurement.
Regulatory agencies
When installed, configured, and used as recommended by Micro Motion, the Weights & Measures application is certified by the following regulatory agencies:
• NTEP (National Type Evaluation Program). NTEP requirements apply in the U.S.A. and Canada.
• OIML (Organization of Legal Metrology). OIML requirements apply in all other world areas.
Depending on the regulatory agency that governs your installation, different setup, configuration, and operation methods are applicable.
Secured vs. unsecured
When the Weights & Measures application is installed, the transmitter is always “secured” or “unsecured.”
The transmitter leaves the factory in unsecured mode, with Status Alarm A027: Security Breach active.
Additionally, flow measurement may be disabled. Measurement data from an unsecured transmitter cannot be used for custody transfer applications.
To clear the alarm and enable flow measurement, you must configure the Weights & Measures application and secure the transmitter. When the transmitter is secured, the alarm is cleared and flow measurement is enabled automatically.
Security types and requirements
Before using the transmitter for Weights & Measures measurement, both metrological security and physical security must be implemented.
Metrological security
Physical security
Metrological security protects the transmitter from all changes that would affect measurement. This includes changes to configuration and some maintenance procedures.
Micro Motion implements metrological security via “software security.” Software security is a setting inside the transmitter that programmatically disables the prohibited actions.
Software security can be enabled or disabled from ProLink III. Practically speaking, software security provides complete protection against unauthorized changes or actions.
Physical security is implemented by a seal installed by a certified Weights & Measures inspector. The seal prevents access to the service port terminals.
Although the seal can be broken easily, it cannot be replaced by anybody other than a
Weights & Measures inspector. This makes it easy to detect that security has been violated. If the seal is not intact, transmitter measurements are not valid for custody transfer.
Configuration methods
You must use ProLink III and a service port connection to configure the Weights & Measures parameters.

8.2 Set up the Weights & Measures application using
ProLink III
When your transmitter is set up to comply with OIML or NTEP requirements, and the transmitter is secured, selected measurement data from the transmitter is approved for Weights & Measures applications.
Prerequisites
Important
Review the Weights & Measures requirements for your location and ensure that you are complying with all local requirements as well as the OIML or NTEP requirements.
If necessary for your installation, arrange for a site visit by a certified Weights & Measures inspector, and ensure that the inspector is present for the appropriate portions of this procedure.
Ensure that the transmitter is ready to be secured, i.e., it is configured as desired and you have performed all appropriate tests and adjustments. After the transmitter is secured, you cannot make any changes to configuration, many maintenance actions are disallowed, and some operator actions are disallowed.
Procedure
1. Make a service port connection from ProLink III to your transmitter.
2. Choose Device Tools → Configuration → Weights & Measures and set Regulatory Agency to the apropriate regulatory agency for your application.
Option
NTEP
OIML
Description

5. If required for your installation, choose Device Tools → Device Information , then read and record the firmware checksum values for the transmitter and the core processor.
The checksum values for the transmitter firmware and the core processor firmware must be read during meter commissioning to meet Weights & Measures requirements for gas applications in
Germany. They may also be useful for MID/Welmec 7.2 test reports.
6. If required for your installation, monitor the zero value of your system: a) Choose Device Tools → Configuration → Transmitter Display → Display Variables and configure Field Verification Zero ( FVZ ) as a display variable.
b) At the transmitter display, read and record the current value of FVZ .
FVZ is a diagnostic variable that monitors the zero value over a period of 3 minutes. It must be read during meter commissioning to comply with MID requirements for Weights & Measures applications in
Measuring Instrument Directive (MID) 2004/22/EC. Refer to your Standard Operating Procedures documentation for detailed instructions.
7. Enable software security: Device Tools → Configuration → Weights & Measures → Software
Security .
Important
Depending on local requirements, this step may need to be witnessed by a certified Weights &
Measures inspector.
After this step, the transmitter is in a condition of metrological security (measurement security). The transmitter performs the following actions:
• Securing all measurement parameters. You can read the current configurations but you cannot change them.
• Clearing Status Alert A027: Security Breach.
8. Install the physical seal.
Important
In most installations, the physical seal is a wire seal that must be installed by a certified Weights &
Measures inspector. The seal is provided by the inspector. The physical seal is inserted through the locking clamps on the transmitter (if available on your transmitter).

10 Operate the transmitter with the Weights
& Measures application
Information in this chapter is applicable only if your transmitter was ordered with the Weights & Measures application.
10.1 Operate the transmitter when the Weights &
Measures application is installed
When the Weights & Measures application is installed, many of the basic functions of the transmitter are modified.
Procedure
• To make a connection:
• If the physical seal is not installed, you can use any supported connection type.
• If the physical seal is installed, you cannot make a service port connection. You can use any other supported connection type.
• To read or obtain process data:
• For an approved measurement, you must use an approved method.
• If the measurement does not have to be approved, you can use any available method.
Important
The behavior of transmitter outputs and process variable values is modified by the Weights & Measures application. Ensure that you know the effects of this application on outputs and process variable values.
• To reset totalizers:
• If the transmitter is unsecured, you can reset totalizers. If you reset one totalizer, all other totalizers are reset automatically.
• If the transmitter is secured, you may or may not be able to reset totalizers, depending on configuration. If totalizer reset is enabled, you cannot reset totalizers unless the flow rate is 0. To reset totalizers from the display, you may need to enter the alarm menu password, whether or not you have enabled it. The default value for Alarm Menu Password is 1234.
• You cannot stop totalizers while the tranmitter is secured.
• You cannot reset inventories while the transmitter is secured.
10.1.1 Approved methods to read or obtain process data
When the Weights & Measures application is installed, process data is approved for custody transfer use only if an approved method is used for reading or obtaining it.
Note
On the primary mA output, HART/Bell 202 communications may be used to poll for either temperature or pressure, in conjunction with process data reporting.

10.1.2 Large totalizer values on the display (OIML applications only)
If Approval is set to OIML and totalizer values become large enough, the display handles large values in a special way. The value displayed may not reflect the actual value.
The display is able to show a maximum of eight characters, including the decimal point. For all totalizer values configured as display variables, the position of the decimal point on the display is fixed to the configured precision of the display variable.
When the totalizer reaches the largest value that can be displayed in these circumstances:
• The digits roll over.
• The decimal point does not move.
• The number of digits on the display does not change.
• The internal totalizer is reset to 0.
For example, the value 99999.999 rolls over to 00000.000.
Tip
If you are not sure whether or not the totalizer value on the display has rolled over, check the value by using another method to read the current data.
Notes
• The mass and volume totalizers do not necessarily roll over at the same time.

10.4 Replacing the core processor in a Weights &
Measures installation
In a Weights & Measures installation, replacing the core processor requires re-sealing the transmitter.
When the transmitter is first secured, the core processor’s unique ID is registered with the transmitter. If you replace the core processor with another core processor, the transmitter will post Status Alarm A026: Sensor/
Xmtr Communication Error. To clear this alarm, you must switch the transmitter to unsecured mode and resecure it. This requires breaking the physical seal and reinstalling it when the entire process is complete.
Other procedures may be required. Refer to the Weights & Measurements documentation for your installation.
Important
In most cases, the physical seal must be installed by a certified Weights & Measures inspector.

11 Measurement support
11.1 Options for measurement support
Micro Motion provides several measurement support procedures to help you evaluate and maintain your flowmeter's accuracy.
The following methods are available:
• Smart Meter Verification (SMV) evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or force divided by displacement. Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance.
• Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. Meter validation requires one data point.
• Calibration establishes the relationship between a process variable and the signal produced at the sensor.
You can calibrate the flowmeter for zero, density, and temperature. Density and temperature calibration require two data points (low and high) and an external measurement for each.
Tip
• Perform SMV at regular intervals to get the best data on your meter's performance.
• To prove the meter against a regulatory standard, or to correct measurement error, use meter validation and meter factors.
• Before performing a field calibration, contact customer support to see if there is an alternative. In many cases, field calibrations have a negative effect on measurement accuracy.
11.2 Use Smart Meter Verification
Smart Meter Verification ™ provides in-process flow meter health verification by analyzing the meter components related to measurement performance. You can run Smart Meter Verification without stopping the process. Use this section to run a Smart Meter Verification test, view and interpret the results, set up automatic execution, and check if a field reference point has been established.
11.2.1 SMV requirements
To use SMV, the transmitter must be paired with an 800 enhanced core processor.
for the minimum version of the transmitter, an 800 enhanced core processor, and communication tool needed to support SMV. (If you are going to perform SMV using the display, only the transmitter and enhanced core processor versions apply.)

11.2.2 SMV test preparation
Prerequisites
The following information pertains to the transmitter when connected to an 800 enhanced core processor greater than or equal to v4.7 .
• To avoid or reduce corrosion, erosion, and other process effects, make sure the sensor tube material is compatible with the process fluid in use. For more information, see the Micro Motion Corrosion Guide .
• Important
Micro Motion highly recommends:
— Running the first Smart Meter Verification test when the flow meter is installed in the pipeline according to the installation instructions, and the process is running at its normal operating conditions
— Running all tests thereafter at similar operating conditions
• The Smart Meter Verification test runs best when process conditions are stable. If process conditions are too unstable, the test will abort. To maximize process stability:
— Maintain a constant fluid temperature and pressure.
— Maintain a constant flow rate. If possible, stop flow through the sensor. The sensor should be full of process fluid.
— Avoid changes to fluid composition; for example, two-phase flow or settling.
• For all applications, run Smart Meter Verification while commissioning the meter at normal operating conditions and then run it regularly. Micro Motion also recommends using Smart Meter Verification results along with other diagnostics like drive gain and density to help determine the health of a sensor.
• In certain scenarios, Smart Meter Verification field upgrades for pre-installed meters are possible. Contact factory support to discuss pre-installed meter upgrades.

Interpreting Smart Meter Verification results
When the Smart Meter Verification Basic or Professional test is completed, the result is reported as Pass, Fail, or Abort. (Some tools report the Fail result as Advisory instead.)
Pass The meter is performing within factory specifications.
Abort When you execute a Smart Meter Verification Basic or Professional test, the test performs a selfdiagnostic check to ensure that the flow meter is stable prior to running the test. In the rare case that this check reveals an issue, Smart Meter Verification will report an abort code.
If you manually cancel an in-process Smart Meter Verification Basic or Professional test, the test result displays Abort Code 1: User-Initiated Abort . In this case, you can restart Smart
Meter Verification without any further action. In the rare case any other abort occurs, contact factory support.
In all cases where a Smart Meter Verification Professional test aborts, no report will be generated.
Fail If a Smart Meter Verification Basic or Professional test ran at normal operating conditions while
conditions were stable and failed, see Resolving a failed Smart Meter Verification test to determine

11.3.1 PVR, TBR, and TMR applications
PVR, TBR, and TMR are applications designed to provide more accurate process data in the presence of multiple phases. For example, if bubbles are present in the process fluid, or the process fluid is flashing, the volume measurements are often incorrect.
Production Volume Reconciliation (PVR)
• Provides oil and water volumes through density-based calculations for both line and reference conditions
• Detects bubble entrainment or flashing in the sensor, and can correct volumes accordingly
• Best for undersized three-phase separators that frequently have intermittent gas or water contamination in the oil leg
• Offers a simple, low-cost solution for net oil and net water measurement for two-phase separators
Transient Bubble Remediation (TBR)
• Used with single-component liquid streams that may experience intermittent low levels of gas entrainment, that is, gas carryunder
• Enables accurate measurement of a single fluid during periods of entrained gas by providing a substitute density value based on the immediately preceding process density (standard configuration)
• Tracks total time of aerated flow to assist in diagnosing process issues that may cause aeration
Transient Mist Remediation (TMR)
• Used with gas streams that may experience intermittent low levels of liquid entrainment, i.e., liquid carryover
• Allows gas measurement to continue during periods of entrained liquid (mist) by providing a substitute flow rate value based on the immediately preceding process flow rate
• Returns to reporting the measured flow rate when the mist interval is over, increased or decreased by a maximum of 10%, until flow totals are appropriately adjusted for the unmeasured flow
• Provides an indication of the amount of time that liquid was present in the stream — identifying process improvements to reduce gas stream contamination
11.4 Piecewise linearization (PWL) for calibrating gas meters
Piecewise linearization (PWL) can linearize the measurements of flow meters for greater accuracy in order to measure gas over a wide range of flow rates. PWL does not apply when measuring liquid flow. When better accuracy is required over the published gas measurement specifications, an Emerson-approved independent gas laboratory can calibrate gas up to 10 PWL adjustment points.
Restriction
You cannot use a field communicator to configure PWL.

Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. If the transmitter value for mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. The flowmeter’s actual measurement is multiplied by the meter factor, and the resulting value is reported and used in further processing.
Prerequisites
Identify the meter factor(s) that you will calculate and set. You may set any combination of the three meter factors: mass flow, volume flow, and density. Note that all three meter factors are independent:
• The meter factor for mass flow affects only the value reported for mass flow.
• The meter factor for density affects only the value reported for density.
• The meter factor for volume flow affects only the value reported for volume flow or gas standard volume flow.
Important
To adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for mass flow and a meter factor for density will not produce the desired result. The volume flow calculations are based on original mass flow and density values, before the corresponding meter factors have been applied.
If you plan to calculate the meter factor for volume flow, be aware that validating volume in the field may be expensive, and the procedure may be hazardous for some process fluids. Therefore, because volume is inversely proportional to density, an alternative to direct measurement is to calculate the meter factor for volume flow from the meter factor for density. See
Alternate method for calculating the meter factor for volume flow
for instructions on this method.
Obtain a reference device (external measurement device) for the appropriate process variable.

Important
For good results, the reference device must be highly accurate.
Procedure
1. Determine the meter factor as follows: a) Set the meter factor to 1 to take a sample measurement.
b) Measure the same sample using the reference device.
c) Calculate the meter factor using the following formula:
NewMeterFactor = ConfiguredMeterFactor ×
ReferenceMeasurement
FlowmeterMeasurement
2. Ensure that the calculated meter factor does not fall outside 0.98 and 1.02. If the meter factor is outside these limits, contact customer service.
3. Configure the meter factor in the transmitter.
Calculating the meter factor for mass flow
The flowmeter is installed and validated for the first time. The mass flow measurement from the transmitter is
250.27 lb. The mass flow measurement from the reference device is 250 lb. The mass flow meter factor is calculated as follows:
MeterFactor
MassFlow = 1 ×
250
250.27
= 0.9989
The first meter factor for mass flow is 0.9989.
One year later, the flowmeter is validated again. The mass flow measurement from the transmitter is
250.07 lb. The mass flow measurement from the reference device is 250.25 lb. The new mass flow meter factor is calculated as follows:
MeterFactor = 0.9996
The new meter factor for mass flow is 0.9996.
11.7.1 Alternate method for calculating the meter factor for volume flow
The alternate method for calculating the meter factor for volume flow is used to avoid the difficulties that may be associated with the standard method.
This alternate method is based on the fact that volume is inversely proportional to density. It provides partial correction of the volume flow measurement by adjusting for the portion of the total offset that is caused by the density measurement offset. Use this method only when a volume flow reference is not available, but a density reference is available.
Procedure
1. Calculate the meter factor for density, using the standard method.

11.8 Perform a (standard) D1 and D2 density calibration
Density calibration establishes the relationship between the density of the calibration fluids and the signal produced at the sensor. Density calibration includes the calibration of the D1 (low-density) and D2 (highdensity) calibration points.
Important
Micro Motion flow meters are calibrated at the factory, and normally do not need to be calibrated in the field.
Calibrate the flow meter only if you must do so to meet regulatory requirements. Contact customer support before calibrating the flow meter.
Tip
Use meter validation and meter factors, rather than calibration, to prove the meter against a regulatory standard or to correct measurement error.
Prerequisites
• During density calibration, the sensor must be completely filled with the calibration fluid, and flow through the sensor must be at the lowest rate allowed by your application. This is usually accomplished by closing the shutoff valve downstream from the sensor, then filling the sensor with the appropriate fluid.
• D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You may use air and water.
• If LD Optimization is enabled on your meter, disable it. To do this, choose Configure → Manual Setup →
Measurements → LD Optimization . LD Optimization is used only with large sensors in hydrocarbon applications. In some installations, only customer service has access to this parameter. If this is the case, contact customer service before continuing.
• If LD Optimization is enabled on your meter, disable it. To do this using a field communicator, choose
Configure → Manual Setup → Measurements → Optional Setup → LD Optimization . LD Optimization is used only with large sensors in hydrocarbon applications. If you are not using a field communicator, contact Emerson before continuing.
• The calibrations must be performed without interruption, in the order shown. Make sure that you are prepared to complete the process without interruption.
• Before performing the calibration, record your current calibration parameters. You can do this by saving the current configuration to a file on the PC. If the calibration fails, restore the known values.
Restriction
For T-Series sensors, the D1 calibration must be performed on air and the D2 calibration must be performed on water.

If you perform the D3 and D4 calibration, note the following:
• Do not perform the D1 and D2 calibration.
• Perform the D3 calibration if you have one calibrated fluid.
• Perform both the D3 and D4 calibrations if you have two calibrated fluids (other than air and water). The calibrations must be performed without interruption, in the order shown. Make sure that you are prepared to complete the process without interruption.

12.2 Check the cutoffs
If the transmitter cutoffs are configured incorrectly, the transmitter may report zero flow when flow is present, or very small amounts of flow under no-flow conditions.
There are separate cutoff parameters for mass flow rate, volume flow rate, gas standard volume flow rate (if applicable), and density. There is an independent cutoff for the mA Output on your transmitter. The interaction between cutoffs sometimes produces unexpected results.
Procedure
Verify the configuration of all cutoffs.

If the transmitter is producing a fixed current from the mA Output, the mA Output Action parameter may be set incorrectly.
When the mA Output Action parameter is set to Fixed, the mA Output produces a fixed value, and does not report process data or implement its fault action.
When HART Address is changed, some configuration tools will automatically change mA Output Action .
Tip
Always verify mA Output Action after setting or changing HART Address .
Procedure
1. Set HART Address as appropriate for your HART network.
The default address is 0. This is the recommended value unless the transmitter is in a multidrop network.
2. Set mA Output Action to Live.
12.19 Check HART

12.26 Check the pickoff voltage
If the pickoff voltage readings are unusually low, you may have any of a variety of process or equipment problems.
To know whether your pickoff voltage is unusually low, you must collect pickoff voltage data during the problem condition and compare it to pickoff voltage data from a period of normal operation.
Drive gain and pickoff voltage are inversely proportional. As drive gain increases, pickoff voltages decrease and vice versa.
Table 12-8: Possible causes and recommended actions for low pickoff voltage
Possible cause
Cavitation or flashing; settling of two-phase or three-phase fluids
Recommended actions
• Increase the inlet or back pressure at the sensor.
Increasing back pressure is recommended. Applying back pressure downstream from the sensor can prevent flashing inside the sensor tubes. That way, if the process fluid is going to flash, it will do so downstream from the sensor after it has been measured.
• If a pump is located upstream from the sensor, increase the distance between the pump and sensor.
• The sensor may need to be reoriented or repositioned.
Consult the installation manual for your sensor.
Faulty wiring runs between the sensor and transmitter
Process flow rate beyond the limits of the sensor
Two-phase flow
Sensor tubes are not vibrating
Moisture in the sensor electronics
The sensor is damaged, or sensor magnets may have become demagnetized
Verify wiring between sensor and transmitter.
Verify that the process flow rate is not out of range of the sensor.
Check for two-phase flow. See Check for two-phase flow
• Check for plugging or deposition.
• Ensure that the vibrating element is free to vibrate (no mechanical binding).
• Verify wiring.
•
Test coils at sensor. See Check the sensor coils

Eliminate the moisture in the sensor electronics.
Replace the sensor.
12.26.1 Collect pickoff voltage data
Pickoff voltage data can be used to diagnose a variety of process and equipment conditions. Collect pickoff voltage data from a period of normal operation, and use this data as a baseline for troubleshooting.
Procedure
1. Navigate to the pickoff voltage data.

2. Observe and record data for both the left pickoff and the right pickoff, over an appropriate period of time, under a variety of process conditions.
12.27 Check power supply wiring
If the power supply wiring is damaged or improperly connected, the transmitter may not receive enough power to operate properly.
Prerequisites
• You will need the installation manual for your transmitter.
• When using DC power, a minimum of 1.5 amps of startup current is required.
Procedure
1. Use a voltmeter to test the voltage at the transmitter power supply terminals.
• If the voltage is within the specified range, you do not have a power supply problem.
• If the voltage is low, ensure that the power supply is adequate at the source, the power cable is sized correctly, there is no damage to the power cable, and an appropriate fuse is installed.
• If there is no power, continue with this procedure.
2.
WARNING
If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. Failure to do so could result in an explosion causing death or injury.
Before inspecting the power supply wiring, disconnect the power source.
3. Ensure that the terminals, wires, and wiring compartment are clean and dry.
4. Ensure that the power supply wires are connected to the correct terminals.
5. Ensure that the power supply wires are making good contact, and are not clamped to the wire insulation.
6. Inspect the voltage label inside the wiring compartment.
The voltage supplied to the transmitter should match the voltage specified on the label.
7.
WARNING
If the transmitter is in a hazardous area, do not reapply power to the transmitter with the housing cover removed. Reapplying power to the transmitter while the housing cover is removed could cause an explosion.
Reapply power to the transmitter.
8. Test the voltage at the terminals.
If there is no power, contact customer service.
12.28 Check for radio frequency interference (RFI)
The transmitter Frequency Output or Discrete Output can be affected by radio frequency interference (RFI).
Possible sources of RFI include a source of radio emissions, or a large transformer, pump, or motor that can generate a strong electromagnetic field. Several methods to reduce RFI are available. Use one or more of the following suggestions, as appropriate to your installation.
Configuration and Use Manual 193
Troubleshooting
October 2022
Configuration and Use Manual
MMI-20019053
Procedure
• Use shielded cable between the output and the receiving device.
— Terminate the shielding at the receiving device. If this is impossible, terminate the shielding at the cable gland or conduit fitting.
— Do not terminate the shielding inside the wiring compartment.
— 360-degree termination of shielding is unnecessary.
• Eliminate the RFI source.
• Move the transmitter.
12.29 Using sensor simulation for troubleshooting
When sensor simulation is enabled, the transmitter reports user-specified values for basic process variables.
This allows you to reproduce various process conditions or to test the system.
You can use sensor simulation to help distinguish between legitimate process noise and externally caused variation. For example, consider a receiving device that reports an unexpectedly erratic density value. If sensor simulation is enabled and the observed density value does not match the simulated value, the source of the problem is likely to be somewhere between the transmitter and the receiving device.
Sensor simulation requires an enhanced core and a communication device.
Important
When sensor simulation is active, the simulated value is used in all transmitter outputs and calculations, including totals and inventories, volume flow calculations, and concentration calculations. Disable all automatic functions related to the transmitter outputs and place the loop in manual operation. Do not enable simulation mode unless your application can tolerate these effects, and be sure to disable simulation mode when you have finished testing.
12.30 Check sensor-to-transmitter wiring
A number of power-supply and output problems may occur if the wiring between the sensor and the transmitter is improperly connected, or if the wiring becomes damaged.
Be sure to check all wiring segments:
• If you have a 9-wire transmitter, check the wiring between the transmitter and the sensor junction box.
Prerequisites
You will need the installation manual for your transmitter.
Procedure
1. Before opening the wiring compartments, disconnect the power source.
WARNING
If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. Failure to do so could result in an explosion causing death or injury.
2. Verify that the transmitter is connected to the sensor according to the information provided in the installation manual.

3. Verify that the wires are making good contact with the terminals.
4. Check the continuity of all wires from the transmitter to the sensor.
12.31 Check for two-phase flow (slug flow)
Two-phase flow can cause rapid changes in the drive gain. This can cause a variety of measurement issues.
Procedure
1. Check for two-phase flow alerts (e.g., A105).
If the transmitter is not generating two-phase flow alerts, verify that two-phase flow limits have been set. If limits are set, two-phase flow is not the source of your problem.
2. Check the process for cavitation, flashing, or leaks.
3. Monitor the density of your process fluid output under normal process conditions.
4. Check the settings of Two-Phase Flow Low Limit , Two-Phase Flow High Limit , and Two-Phase Flow
Timeout .
Tip
You can reduce the occurrence of two-phase flow alerts by setting Two-Phase Flow Low Limit to a lower value, Two-Phase Flow High Limit to a higher value, or Two-Phase Flow Timeout to a higher value. Micro Motion recommends leaving the Two-Phase Flow High Limit at the default value.

• Wait two minutes until the display times out and returns to displaying process variable data.
A.3.1 Enter a floating-point value using the display
Certain configuration values (for example, Lower Range Value and Upper Range Value ) are entered as floating-point values. The display supports both decimal notation and exponential notation for floating-point values.
The display allows you to enter a maximum of 8 characters, including the sign. The decimal point is not counted as a character. Exponential notation is used to enter values that require more than 8 characters.
A.3.1 Enter a floating-point value using decimal notation
Decimal notation allows you to enter values between –9999999 and 99999999. You can use the decimal point to enter values with a precision of 0 through 4 (4 characters to the right of the decimal point).
Decimal values entered via the display must meet the following requirements:
• They can contain a maximum of 8 digits, or 7 digits plus a minus sign ( − ) to indicate a negative number.
• They can contain a decimal point. The decimal point does not count as a digit. The decimal point must be positioned so that the precision of the value does not exceed 4.
When you first enter the configuration screen, the current configuration value is displayed in decimal notation, and the active character is flashing. If the value is positive, no sign is displayed. If the value is negative, a minus sign is displayed.
Procedure
• To change the value: a) Activate Select until the digit you want to change is active (flashing).
Select moves the cursor one position to the left. From the leftmost position, Select moves the cursor to the rightmost digit.
b) Activate Scroll to change the value of the active digit.

B.2 Connect with ProLink III
A connection from ProLink III to your transmitter allows you to read process data, configure the transmitter, and perform maintenance and troubleshooting tasks.
B.2.1 Connection types supported by ProLink III
Different connection types are available for connecting from ProLink III to the transmitter. Choose the connection type appropriate to your network and the tasks you intend to perform.
The transmitter supports the following ProLink III connection types:
• Service port connections
• HART ® /Bell 202 connections
When selecting a connection type, consider the following:
• Service port connections are specialized Modbus/RS-485 connections that use standard connection parameters and a standard address that are already defined in ProLink III. Service port connections are typically used by field service personnel for specific maintenance and diagnostic functions. Use a service port connection only when another connection type does not provide the functionality you need.
• HART/Bell 202 connections use standard HART connection parameters that are already defined in
ProLink III. The only parameter you must configure is the transmitter address.
• Some connection types require opening the wiring compartment or the power supply compartment.
These connection types should be used only for temporary connections, and may require extra safety precautions.
• When you are using a HART connection, ProLink III will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed.
• You cannot make concurrent Modbus connections if the connections use the same terminals. You can make concurrent Modbus connections if the connections use different terminals.
