Configure Gas Standard Volume Flow Cutoff - Emerson Micro Motion 2700 Configuration And Use Manual

The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for gas standard volume flow
You want to measure gas standard volume flow in thousands of standard cubic feet per
minute.

Overview
Gas Standard Volume Flow Cutoff specifies the lowest gas standard volume flow rate that
will reported as measured. All gas standard volume flow rates below this cutoff will be
reported as 0.
Procedure
Set Gas Standard Volume Flow Cutoff to the value you want to use.
The default value for Gas Standard Volume Flow Cutoff is 0.0. The lower limit is 0.0. There
is no upper limit.
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 via the mA Output. If mA Output Process Variable is set to Gas
Standard Volume Flow Rate, the volume flow rate reported via the mA Output is controlled by
the higher of the two cutoff values.
Configuration and Use Manual
Set Base Gas Standard Volume Unit to SCF.
Set Base Time Unit to minutes (min).
Calculate the conversion factor:
a. 1 thousands of standard cubic feet per minute = 1000 cubic feet per minute
b. Gas Standard Volume Flow Conversion Factor = 1 ÷ 1000 = 0.001 standard
Set Gas Standard Volume Flow Conversion Factor to 0.001.
Set Gas Standard Volume Flow Label to MSCFM.
Set Gas Standard Volume Total Label to MSCF.
