Configure Gas Standard Volume Flow Measurement - Emerson Micro Motion 9739 MVD Configuration And Use Manual

Configure process measurement
Result:
• If the volume flow rate drops below 15 liters/second but not below 10 liters/second:
− 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 volume flow rate drops below 10 liters/second, both outputs will report zero flow, and 0 will
be used in all internal processing.

The gas standard volume flow measurement parameters control how gas standard volume flow is
measured and reported.
The gas standard volume flow measurement parameters include:
• Volume Flow Type
• Standard Gas Density
• Gas Standard Volume Flow Measurement Unit
• Gas Standard Volume Flow Cutoff
Restriction
You cannot implement both liquid volume flow and gas standard volume flow. You must choose one or
the other.

Field Communicator Configure→Manual Setup→Measurements→Gas Standard Volume→Volume Flow Type→GSV
Volume Flow Type controls whether liquid or gas standard volume flow measurement will be implemented.
Restriction
If you are using the petroleum measurement application, you must set Volume Flow Type to Liquid. Gas
standard volume measurement is incompatible with the petroleum measurement application.
