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.
