Set up pressure compensation using the display

Pressure compensation adjusts process measurement to compensate for the pressure
effect on the sensor. The pressure effect is the change in the sensor's sensitivity to flow
and density caused by the difference between the calibration pressure and the process
pressure.
Prerequisites
You will need the flow factor, density factor, and calibration pressure values for your
sensor.
•
•
You must be able to supply pressure data to the transmitter.

For the flow factor and density factor, see the product data sheet for your sensor.
For the calibration pressure, see the calibration sheet for your sensor. If the data is
unavailable, use 20 PSI.
Choose Menu > Configuration > Process Measurement > Pressure.
Set Units to the pressure unit used by the external pressure device.
Enter Flow 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.
Enter Density Factor for your sensor.
The density factor is the change in fluid density, in g/cm
value, reverse the sign.
Example:
If the density factor is 0.000006 g/cm
Set 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.
Choose the method to be used to supply pressure data, and perform the required
setup.
