Using Prolink Ii - Emerson Micro Motion 2400S Configuration And Use Manual

Optional Configuration
Only one type of volume flow measurement can be performed at a time (i.e., if liquid volume flow
measurement is enabled, gas standard volume flow measurement is disabled, and vice versa).
Different sets of volume flow measurement units are available, depending on which type of volume
flow measurement is enabled (see Tables 6-3 and 6-4). If you will use a gas standard volume flow
unit, additional configuration is required.
Note: If you will use the petroleum measurement application or the enhanced density application,
liquid volume flow measurement is required.
The method used to configure volume flow measurement for gas depends on the tool you are using:
ProLink II or a DeviceNet tool.
Note: For complete configuration of volume flow measurement for gas, you must use either ProLink II
or a DeviceNet tool. Using the display, you can only select a volume measurement unit from the set
available for the configured volume flow type.

Using ProLink II

To configure volume flow measurement for gas using ProLink II:
1. Click
ProLink > Configure > Flow
2. Set Vol Flow Type
3. Select the measurement unit you want to use from the

5. If you know the standard density of the gas that you are measuring, enter it in the
field. If you do not know the standard density, you can use the Gas Wizard. See the
Density
following section.
Note: The term "standard density" refers to the density of the gas at reference conditions.
Using the Gas Wizard
The Gas Wizard is used to calculate the standard density of the gas that you are measuring.
To use the Gas Wizard:
1. Click ProLink > Configure > Flow

c. Provide the required information. Note that if you selected
value in the configured density units and you must provide the temperature and pressure at
which the density value was determined.
Note: Ensure that the values you enter are correct, and that fluid composition is stable. If either of
these conditions is not met, gas flow measurement accuracy will be degraded.
