4. If you chose a C table, enter
Thermal Expansion Coefficient (TEC)
for your process fluid.
5. Set
Reference Temperature
to the temperature to which density will be corrected in referred density
calculations. If you choose Other, select the temperature measurement unit and enter the reference
temperature.
6. Set
Reference Pressure
to the pressure to which density will be corrected in referred density
calculations.
Set up temperature and pressure data for API referral using ProLink III
The API referral application uses temperature and, optionally, pressure data in its calculations. You must
decide how to provide this data, then perform the required configuration and setup.
Pressure data is required for the following API tables: All A tables, all B tables, all C tables, and all D tables. E
tables do not require pressure data.
Tip
Fixed values for temperature or pressure are not recommended. Using a fixed temperature or pressure value
may produce inaccurate process data.
Prerequisites
If you plan to poll an external device, the primary mA Output (Channel A) must be wired to support HART
communications.
If you plan to use the mA Input for temperature data, Channel D must be available for use, and must be wired
to an external temperature device.
If you plan to use the mA Input for pressure data, Channel D must be available for use, and must be wired to
an external pressure device.
Restriction
You can use the mA Input for either external temperature or external pressure, but not both.
The pressure measurement must be gauge pressure, not atmospheric pressure.
The pressure device must use the pressure unit that is configured in the transmitter.
If you are using an external temperature device, it must use the temperature unit that is configured in the
transmitter.
