14.4.3 Configure pressure compensation using the Field
Communicator
Procedure
1. Choose Configure > Manual Setup > Measurements > Optional Setup > External Pressure/
Temperature > Pressure.
2. Set Pressure Unit to the unit used by the external pressure device.
3. Enable Pressure Compensation.
4. Set Flow Calibration Pressure to the pressure at which your sensor was calibrated.
The calibration pressure is the pressure at which your sensor was calibrated, and defines the pressure at
which there is no pressure effect. If the data is unavailable, enter 20 PSI.
5. Enter Flow Press Factor for your sensor.
The flow factor is the percent change in the flow rate per PSI. When entering the value, reverse the
sign.
Example
If the flow factor is 0.000004 % per PSI, enter −0.000004 % per PSI.
6. Enter Density Pressure Factor for your sensor.
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.
7. Choose the method to be used to supply pressure data, and perform the required setup.
