Introduction and Scope

The procedures and techniques shown in this document are recommended for use with new measurement applications. Gas measurement using existing equipment and techniques not in compliance with this standard may have a higher uncertainty than that based on the recommendations contained in this document.

This standard describes the minimum specifications for electronic gas measurement systems used in the measurement and recording of flow parameters of gaseous phase hydrocarbon and other related fluids for production and transmission custody transfer applications utilizing industry- recognized primary measurement devices. For the purpose of this standard, electronic correctors of the type used on linear meters were not considered to constitute an electronic gas measurement system.
