Abstract: API 21.1 is recognized as an international industry standard documentingAPI 21.1 is recognized as an international industry standard documenting the electronic gas measurement (EGM) system audit and record requirements for differential and linear meter measurement. This standard is used throughout the measurement community to reduce overall EGM system uncertainty and improve measurement data integrity. Measurement data integrity plays a critical part in measurement accuracy for all organizations and generally has a direct impact to the financial bottom line of your organization. Measurement integrity is also vital for ensuring compliance with regulatory and industry standard requirements. On August 1, 1993, the first edition of the American Petroleum Institute (API) Manual of Petroleum Measurement Standards (MPMS) Chapter 21.1 Flow Measurement Using Electronic Metering Systems-Electronic Gas Measurement was released following a four-year collaborative effort. This document provided the industry with a much-needed standard for several key areas related to custody transfer gas measurement using flow computers. the electronic gas measurement (EGM) system audit and record requirements for differential and linear meter measurement.
