4.7 Configure the petroleum measurement
application
The petroleum measurement application enables Correction for the effect of Temperature
on the volume of Liquids (CTL), by calculating and applying a Volume Correction Factor
(VCF) to volume measurement. Internal calculations are performed in compliance with
American Petroleum Institute (API) standards.
4.7.1 Configure petroleum measurement using ProLink II
1. Choose ProLink > Configuration > API Setup.
2. Specify the API table to use.
a. In API Chapter 11.1 Table Type, select the API table group.
b. In Units, select the the measurement units you want to use.
These two parameters uniquely specify the API table.
3. If your API table is 53A, 53B, 53D, or 54C, set Reference Temperature to the appropriate
value for your application. Enter the value in °C.
4. If your API table is 6C, 24C, or 54C, set Thermal Expansion Coefficient to the appropriate
value for your application.
5. Determine how the transmitter will obtain temperature data for the petroleum
measurement calculations, and perform the required setup.
