Abstract: In natural gas custody and allocation measurement, the users typically installed and operated their orifice meters according to ANSI/API 2530 (AGA 3) standard. It is not a common pracrice now to prove orifice meters in field operation. however, the recent revision of ANSI/API 2530, Part 1, standard for orifice meter flow measurement allows users to prove meters under operating conditions using the acrual fluid with the acrual orifice plate and redording system in place. The standard recognizes that when accurate measurement is required, any deviation from the standards specifications will result in a higher measurement uncertainty.
