API RP 17S:2015

This document provides recommendations for the sizing, specification, system integration, and testing of subsea flow meters [henceforth referred to as multiphase flow meters (MPFMs)] for measurement of full stream, multiphase flow. This Recommended Practice (RP) includes wet gas flow meters as a subset of MPFMs. In-line MPFMs are typically used in subsea applications and are the focus of this RP. These recommendations and guidelines are intended for use by the engineer responsible for the delivery of the MPFM. Due to the nature of multiphase flow measurement it is anticipated that a cross-disciplinary team may be involved throughout its deployment and operational life.
