API MPMS Ch. 22.2

API MPMS Ch. 22.2 is a technical API document for Testing Protocols—Differential Pressure Flow Measurement Devices, issued as the 2nd edition in 2017. It is intended for professionals who need a clear reference for how these flow measurement devices are tested and evaluated in a controlled, standardized way. For engineering, procurement, QA/QC, inspection, and operations teams, this document helps support consistent technical review, specification alignment, and product acceptance decisions where differential pressure flow measurement is involved.

Purpose of API MPMS Ch. 22.2

The purpose of API MPMS Ch. 22.2 is to provide a recognized technical benchmark for testing protocols associated with differential pressure flow measurement devices. As an API MPMS chapter, it serves as a practical reference for establishing consistent test expectations and supporting disciplined evaluation of measurement equipment. Buyers and technical teams may use it to align internal requirements, compare supplier documentation, and support quality-focused review of flow measurement applications. It is especially relevant where reliable measurement practice and repeatable test methods matter.

Common use cases of API MPMS Ch. 22.2

API MPMS Ch. 22.2 is commonly used in engineering and operational settings involving differential pressure flow measurement devices in oil and gas, refining, terminals, pipeline systems, and related process facilities. It may support project specification work, technical submittals, inspection planning, and equipment verification during procurement or maintenance activities. Engineering, operations, inspection, and quality teams may refer to it when evaluating whether a device or testing approach is appropriate for a defined measurement service. It is also useful for documentation control and internal technical review.

Why API MPMS Ch. 22.2 matters

API MPMS Ch. 22.2 matters because flow measurement testing affects confidence in equipment selection, performance review, and operational consistency. A clear testing reference can help reduce ambiguity between suppliers and buyers, support more consistent QA/QC decisions, and improve communication across engineering and inspection functions. For organizations that rely on differential pressure flow measurement devices, this document helps anchor technical expectations to a recognized API reference, which can be valuable for reliability, compliance-oriented review, and day-to-day specification management.
