8 Micro Motion 2700 Transmitters with FOUNDATION Fieldbus
Configuration and Use Manual Quick start
20000326 August 2022
2 Quick start
2.1
The transmitter must be powered up for all configuration and commissioning tasks or for process
measurement.
Procedure
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.
Power up the transmitter
1.
2.
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.
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.
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.

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.
The special unit label displays only on the local display. The AI block uses and displays the actual engineering
unit (i.e. lb/min).
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
18 Micro Motion 2700 Transmitters with FOUNDATION Fieldbus
Configuration and Use Manual Configure process measurement
20000326 August 2022
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
Fieldbus host Measurement TB → FLOW_DAMPING → OD Index
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.
• Default: 0.8 seconds
• Range: 0 seconds to 51.2 seconds
• Valid damping values: 0.0, 0.1, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, 25.6, 51.2
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.
Configuration and Use Manual 19
Configure process measurement Configuration and Use Manual
August 2022 20000326
• The combination of a high damping value and rapid, large changes in flow rate can result in increased
measurement error.
• Whenever the damping value is non-zero, the reported measurement will lag the actual measurement
because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less lag time
between the actual measurement and the reported value.
The value you enter is automatically rounded 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.

Display Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow

Fieldbus host Measurement TB → MASS_LOW_CUT (OD Index 38)
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.
Configure Mass Flow Cutoff
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.
