For the calibration pressure, see the calibration sheet for your sensor. If the data is
unavailable, use 20 PSI.
Choose Device Tools > Configuration > Process Measurement > Pressure
Compensation.
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.
Enter Flow Calibration Pressure for your sensor.
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.
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
Choose Online > Configure > Manual Setup > Measurements > External Inputs.
Set Pressure Compensation to Enabled.
Enter Flow Cal Pressure for your sensor.
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.
Enter Flow Press Factor for your sensor.
