4.7.2 Set up temperature data for petroleum measurement
using ProLink III
The petroleum measurement application uses temperature data in its calculations. You
must decide how to provide this data, then perform the required configuration and setup.
Tip
Fixed values for temperature are not recommended. Using a fixed temperature 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 are using an external temperature device, it must use the temperature unit that is
configured in the transmitter.

Option Description
Internal RTD tem- Temperature data from the on-
perature data board temperature sensor
(RTD) is used.
Configuration and Use Manual
b. Verify that the referred density range of the selected table is adequate for your
application.
If you chose a C table, enter Thermal Expansion Coefficient (TEC) for your process
fluid.
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.
Choose Device Tools > Configuration > Process Measurement > Petroleum
Measurement.
Choose the method to be used to supply temperature data, and perform the
required setup.
Setup
a. Set Line Temperature Source to Internal RTD.
b. Click Apply.
