Volume correction techniques
Custody transfers and billing are used based on volumes at a given temperature,
or Standard Temperature. FuelsManager provides the following temperature
correction techniques. All correction techniques are based on internationally
recognized standards developed by the American Petroleum Institute (API),
American Society for Testing and Materials (ASTM), Institute of Petroleum (IP),
Japanese Institute of Standards (JIS), Gosstandart of Russia (GOST), and
Chinese National Standards (GB/T).
The goal of a correction technique is to calculate a Volume Correction factor
(VCF) and to use this factor to calculate standard volumes from measured
volumes. The VCF is defined as:
• Correction for temperature for a liquid
• Compensates for the effect of temperatures on a liquid
• Corrects a volume at an observed temperature to a standard temperature
