Petroleum Measurement Manual

Measurement accuracy is essential in the sale, purchase and handling of petroleum products, avoiding disputes between buyer and seller and providing control over losses. Accurate measurement involves the use of standard equipment and procedures. This manual standardizes conditions for manually obtaining a sample of liquid or semi-liquid hydrocarbons from a tank, drum or pipeline. In addition, a procedure is included for transfer and subsequent handling of the sample to ensure delivery of a representative sub-sample into laboratory apparatus or into storage for retention.
