Set up pressure compensation using a web browser

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.

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
value, reverse the sign.
Example:
If the density factor is 0.000006 g/cm
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.
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.
Choose the method you will use to supply pressure data, and perform the required
setup.
If the value is not correct:
Ensure that the external device and the meter are using the same measurement unit.
For digital communications:
- Verify that the host has access to the required data.

Setup
a. Set Pressure Source to Fixed Value or Digital Communications.
b. Perform the necessary host programming and communica-
tions setup to write pressure data to the meter at appropri-
ate intervals.
