If the value is not correct:
• Ensure that the external device and the meter are using the same measurement unit.
• For polling:
— Verify the wiring between the meter and the external device.
— Verify the HART tag of the external device.
13.4.2 Set up pressure compensation using ProLink III
Procedure
1. Choose Device Tools → Configuration → Process Measurement → Pressure Compensation.
2. Set Pressure Compensation Status to Enabled.
3. Set Pressure Unit to the unit used by the external pressure device.
4. Enter the Density Factor and Flow Factor for your sensor.
a) Set Process Fluid to Liquid Volume or Gas Standard Volume, as appropriate.
b) Compare the values shown in Recommended Density Factor and Recommended Flow Factor to
the values from the product data sheet.
c) To use the recommended values, click Accept Recommended Values.
d) To use different factors, enter your values in the Density Factor and Flow Factor fields.
The density factor is the change in fluid density, in g/cm
3
/psi. When entering the value, reverse
the sign.
Example
If the density factor is −0.000006 g/cm
3
/psi, enter +0.000006 g/cm
3
/PSI.
The flow factor is the percent change in the flow rate per psi. When entering the value, reverse
the sign.
