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.
4. Enter
Density 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/cm3/PSI.
5. Enter 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.
6. Determine how the transmitter will obtain pressure data, and perform the required
setup.
Option Setup
A user-configured
static pressure val-
ue a. Set
Pressure Units
to the desired unit.
b. Set
External Pressure
to the desired value.
Polling for pressure a. Ensure that the primary mA output has been wired to support
HART polling.
b. Choose ProLink > Configuration > Polled Variables .
c. Choose an unused polling slot.
d. Set
Polling Control to Poll As Primary or Poll as Secondary , and click
Apply .
e. Set External Tag to the HART tag of the external pressure device.
f. Set Variable Type to Pressure .
Tip
•
Poll as Primary
: No other HART masters will be on the network.
• Poll as Secondary : Other HART masters will be on the network.
The Field Communicator is not a HART master.
