Configuration and Use Manual
MMI-20048166
Procedure
Set Volume Flow Type to Gas.
4.4.2 Configure Standard Gas Density
Display Menu > Configuration > Process Measurement > Flow Variables > Volume Flow Settings > Standard Gas

ProLink III Device Tools > Configuration > Process Measurement > Flow > Standard Density of Gas
Field Communicator Configure > Manual Setup > Measurements > Optional Setup > GSV > Gas Ref Density
Standard Gas Density is the density of your gas at reference temperature and reference pressure. This is
often called standard density or base density. It is used to calculate the GSV flow rate from the mass flow rate.
Procedure
Set Standard Gas Density to the density of your gas at reference temperature and reference pressure.
You can use any reference temperature and reference pressure that you choose. It is not necessary to
configure these values in the transmitter.
Tip
ProLink III provides a guided method that you can use to calculate the standard density of your gas, if you do
not know it.
4.4.3 Configure Gas Standard Volume Flow Measurement Unit

Field Communicator
Gas Standard Volume Flow Measurement Unit specifies the unit of measure that will be used for the gas
standard volume (GSV) flow rate. The unit used for gas standard volume total and gas standard volume
inventory is derived from this unit.
Prerequisites
Before you configure Gas Standard Volume Flow Measurement Unit, be sure that Volume Flow Type is set
to Gas Standard Volume.
Procedure
Set Gas Standard Volume Flow Measurement Unit to the unit you want to use.
• Default: SCFM (Standard Cubic Feet per Minute)
Tip
If the measurement unit you want to use is not available, you can define a special measurement unit.
