2 Quick start
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks or for process
measurement.
Procedure
1. 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.
Configuration and Use Manual 13
Quick start Configuration and Use Manual
May 2022 MMI-20019048
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.

ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Mass Flow Unit
Mass Flow Measurement Unit specifies the unit of measure that will be used for the mass flow rate. The unit
used for mass total and mass inventory is derived from this unit.
You can configure the mA and Frequency Outputs independently. For example, you can configure the mA
Output for mass flow and the Frequency Output for liquid volume or gas standard volume. If the same
process variable is assigned to both the mA and Frequency Outputs, then any selected measurement unit,
(mass, volume or gas standard volume), is automatically applied to both outputs.
Procedure
Set Mass Flow Measurement Unit to the unit you want to use.
The default setting for Mass Flow Measurement Unit is g/sec (grams per second).
Tip
If the measurement unit you want to use is not available, you can define a special measurement unit.
Options for Mass Flow Measurement Unit
The transmitter provides a standard set of measurement units for Mass Flow Measurement Unit, plus one
user-defined special measurement unit. Different communications tools may use different labels for the
units.

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

6. Set Mass Total Label to the name you want to use for the mass total and mass inventory unit.
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
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625
4. Set Mass Flow Conversion Factor to 0.0625.
5. Set Mass Flow Label to oz/sec.
6. Set Mass Total Label to oz.
4.1.2 Configure Flow Damping
Display Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Flow Damping
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies
the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end
of the interval, the internal value will reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
The default value is 0.8 seconds. The range depends on the core processor type and the setting of Update
Rate, as shown in the following table.
Update Rate setting
Normal 0 to 51.2 seconds
Special 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 Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Mass Flow Cutoff
Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All mass flow rates
below this cutoff will be reported as 0.
Procedure
Set Mass Flow Cutoff to the value you want to use.
The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the factory. The
recommended value is 0.5% of the nominal flow rate of the attached sensor. See the sensor specifications. 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.

• mA Output Cutoff: 10 g/sec
• Mass Flow Cutoff: 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0 will be used in all
internal processing.
Example: Cutoff interaction with mA Output Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 15 g/sec
• Mass Flow Cutoff: 10 g/sec
Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
— The mA Output will report zero flow.
— The Frequency Output will report the actual flow rate, and the actual flow rate will be used in all
internal processing.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0 will be used in all
internal processing.
4.2 Configure volume flow measurement for liquid

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:
