Configure pressure compensation
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.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific
sensor model can be found in the product data sheet located at
. If you are
uncertain about implementing pressure compensation, contact customer service.
Prerequisites
You will need the flow factor, density factor, and calibration pressure values for your
sensor.
•
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.
4.9.1
Configure pressure compensation using ProLink III
1.
Choose Device Tools > Configuration > Process Measurement > Pressure
Compensation.
2.
Set Pressure Compensation Status to
Enabled
.
3.
Set Pressure Unit to the appropriate unit.
If you will use an external pressure value, set Pressure Unit to match the pressure
unit used by the external pressure device.
4.
Enter Flow Calibration Pressure for your sensor.
