3. 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.
4. 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 −0.0002% per PSI, enter +0.0002 % per PSI.
5. 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.
6. Choose the method to be used to supply pressure data, and perform the required setup.

Digital
communications
A host writes pressure data
to the meter at appropriate
intervals.
a. Using a field communicator, choose Configure
→ Manual Setup → Measurements → Optional Setup →
External Pressure/Temperature → Pressure.
b. Set Pressure Compensation to Enable.
c. Perform the necessary host programming and
communications setup to write pressure data to the
transmitter at appropriate intervals.

Meter validation compares flow meter measurements reported by the transmitter to an external
measurement standard. If the transmitter value for mass flow, volume flow, or density measurement is
significantly different from the external measurement standard, you may want to adjust the corresponding
meter factor. The flow meter’s actual measurement is multiplied by the meter factor, and the resulting value is
reported and used in further processing.
Changing a meter factor is very uncommon. Usually, it's done by official, legal proving companies. And the
meter factor is typically changed in the PLC, not at the meter.
