API MPMS 21.2, 1st Edition, December 2023 - Manual of Petroleum Measurement Standards Chapter 21-Flow Measurement Using Electronic Metering Systems Section 2-Electronic Liquid Volume Measurement Using Positive Displacement and Turbine Meters

GENERAL

This standard provides guidance for effective utilization of electronic liquid measurement systems for custody transfer measurement of liquid hydrocarbons:

• a. Within the scope and field of application of API MPMS Chapter 12.2.
• b. Which are single-phase liquids at measurement conditions.
• c. For systems utilizing turbine or positive displacement meters.
• d. For systems using on-line CTL and CPL compensation.

The procedures and techniques discussed in this document are recommended for use with new measurement applications. Liquid measurement using existing equipment and techniques not in compliance with this standard may have a higher uncertainty than liquid measurement based on the recommendations contained in this document.

ELECTRONIC LIQUID MEASUREMENT (ELM)

The term “electronic liquid measurement,” or ELM, will be freely used throughout this document to denote liquid measurement using electronic metering systems. (Also see 3.20.)
