6.4.3Special volume flow unit

To create a special volume flow measurement unit:

1.Specify the base volume unit.

2.Specify the base time unit.

3.Specify the volume flow conversion factor.

4.Assign a name to the new special volume flow measurement unit.

5.Assign a name to the volume totalizer measurement unit.

6.4.4Special unit for gas

For many gas applications, standard or normal volume flow rate is used as the quasi mass flow rate. Standard or normal volume flow rate is calculated as the mass flow rate divided by the density of the gas at a reference condition.

To configure a mass flow special unit that represents standard or normal volume flow rate, you must calculate the mass flow conversion factor from the density of the gas at a reference temperature, pressure, and composition.

ProLink II offers a Gas Unit Configurator tool to calculate this mass flow conversion factor. The tool will automatically update the mass flow conversion factor in the Special Units tab. If ProLink II is not available, special mass units can be used to set up standard or normal volume flow units for gas applications.

Note: Micro Motion recommends that you do not use the flowmeter to measure actual volume flow of a gas (volumetric flow at line conditions). If you need to measure actual volume flow, contact Micro Motion customer support.

CAUTION

The flowmeter should not be used for measuring the actual volume of gases.

Standard or normal volume is the traditional unit for gas flow. Coriolis flowmeters measure mass. Mass divided by standard or normal density yields standard or normal volume units.

To use the Gas Unit Configurator:

1.Start ProLink II and connect to your transmitter.

2.Open the Configuration window.

3.Click the Special Units tab.

4.Click the Gas Unit Configurator button.

5.Select the Time Unit that your special unit will be based on.

6.Click a radio button to specify that your special unit will be defined in terms of English Units or SI (Système International) Units.

7.Click Next.
