If you want to use digital communications, click Apply, then perform the necessary
host programming and communications setup to write pressure data to the
transmitter at appropriate intervals.

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.
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 Dens Press 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
Determine how the transmitter will obtain pressure data, and perform the required
setup.
