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.

GSV Flow Unit
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.
