Configuring volume flow measurement for gas

Note: Volume flow measurement for gases cannot be configured using the Communicator. If the
flowmeter is configured to use a gas standard volume flow unit, the Communicator will display the
correct value, but will display "Unknown Enumerator" for the units label.
The display cannot be used to configure Vol Flow Type. However, after Vol Flow Type has been
configured using ProLink II, the volume flow unit can be configured.
Special functionality is provided in ProLink II for measuring the volume flow of gases. To access this
functionality:
1. Click
ProLink > Configure > Flow
2. Set
Vol Flow Type
3. Select the measurement unit you want to use from the
The default is
Note: When Vol Flow Type is set to Std Gas Volume, this list contains the units that are most
frequently used for gas measurement. If Liquid Volume is configured, gas measurement units are not
available.

5. If you know the standard density of the gas that you are measuring, enter it in the
Density
following section.
Note: The term "standard density" refers to the density of the gas at reference conditions.
Note: Ensure that the values entered here are correct, and that fluid composition is stable. If either of
these conditions is not met, gas flow measurement accuracy will be degraded.
