Standard gas volume flow and liquid volume flow are mutually exclusive settings. When the Vol Flow
Type is set to Std Gas Volume, the units list contains the units that are most frequently used for gas
measurement. If Liquid Volume is configured, gas measurement units are not available.
To configure the transmitter to use gas standard volume flow:
1. Choose
ProLink > Configure > Flow
2. Set Vol Flow Type
3. Select the measurement unit you want to use from the
default is
4. Configure the
You have two choices for entering the standard density of the gas you are going to measure (i.e., the
density of the gas at reference conditions):
• If you know the standard density, you can enter that value in the
optimal standard volume measurement accuracy, be sure the standard density you enter is
correct and fluid composition is stable.
• If you do not know the standard density of the gas, you can use the Gas Wizard (see
Section 8.4.1). The Gas Wizard can calculate the standard density of the gas that you are
measuring.

Using the Gas Wizard

The Gas Wizard is a tool provided in ProLink II for calculating the standard density of the gas that
you are measuring.
To use the Gas Wizard:
1. Choose
ProLink > Configure > Flow
2. Click Gas Wizard
3. If your gas is listed in the

b. Select your gas.
Configuration and Use Manual
Special functionality is provided for measuring the standard volume flow of gases.
ProLink II is required to access this functionality. Other tools provide only limited
support:
• The Communicator cannot be used to configure volume flow meaurement
for gas or to select a standard gas volume flow measurement unit. If standard
gas volume flow measurement has been configured, the Communicator will
display the correct volume flow value, but will display "Unknown
Enumerator" for the units label.
• The local display cannot be used to change the volume flow type. However,
after the transmitter has been configured for standard gas volume flow
measurement, the display can be used to select a standard gas volume flow
measurement unit.
