Annotation of standard text API MPMS 5.6-ed.2 :

API MPMS 5.6, 2nd Edition, December 2021 - Manual of Petroleum Measurement Standards Chapter 5.6 - Measurement of Liquid Hydrocarbons by Coriolis Meters

This standard is intended to be a guide for the specification, installation, verification, and operation of Coriolis meters used to dynamically measure liquid hydrocarbons. API MPMS Ch. 5.6 also includes information that will assist in troubleshooting and improving the performance of the meters.

Use of a Coriolis meter as a stand-alone density meter is not addressed by this standard.

Field of Application

This standard describes methods to achieve custody transfer measurement of liquid hydrocarbon quantities (mass or volume) using a Coriolis meter. Coriolis meters can provide outputs for mass flow rate, volumetric flow rate, and density. The choice of the quantity output (mass or volume) depends on commercial, contractual, regulatory, and performance requirements.

This document provides guidance for the application, installation, proving, mass calculations, auditing, reporting, and security requirements for Coriolis meters.

Some of the guidance provided within also applies to allocation measurement. API MPMS Ch. 20[19] allows for different performance requirements.

Guidance for the measurement of density is found in API MPMS Ch. 9[6].
