API Standards for Multiphase Metering

• API MPMS 20.3: Measurement of Multiphase Flow (COPM)– First edition, Jan 2013

• API RP 17S: Recommended Practice for the Design, Testing and Operation of Subsea Multiphase Flow Meters (CSOEM, SC17)– First Edition, June 2015

Documents Scope• API MPMS 20.3: Measurement of Multiphase Flow

– Surface and Subsea– Multiphase (including wetgas)– Allocation quality measurement– Multiphase flow measurement principles, types and classifications– Calibration, flow loop testing, in-situ verification– For Measurement Engineers

• API RP 17S: Recommended Practice for the Design, Testing and Operation of Subsea Multiphase Flow Meters– Subsea only– Recommendations for specification, sizing, system integration, testing– Points to other API standards for qualifications testing and reliability– For Delivery Engineers

• Verification+ – the process of confirming the accuracy of a meter (20.3)• Verification* – the process that determines the extent to which a … product conforms to its specifications (17S)

Shall – Should Strategy• API puts this language in every published document:

– Shall: As used in a standard, “shall” denotes a minimum requirement in order to conform to the specification– Should: As used in a standard, “should” denotes a recommendation or that which is advised but not required in order to conform to the specification

• MPMS 20.3– Shall and Should used according to API language– 71 Shall and 162 Should

• API 17S– Shall referencing published API standard (E.g.: API 6A, API 17D, API 17F, API 17N)– Should for all recommendations– 33 Shall and 276 Should
