API MPMS Chapter 14.13 First Edition PDF
This document, for single-phase gas measurement, provides guidance in the following areas to allow the user to achieve a targeted uncertainty of measurement:
– selection of flow meter type: differential pressure, displacement, ultrasonic, Coriolis, vortex, turbine, thermal, and others;
– associated instrumentation for measuring fluid properties and flowing conditions, such as pressure and temperature transmitters, densitometers, gas chromatographs;
– obtaining and use of gas composition or other analytical data;
-design and installation requirements of the measurement system;
– inspection, verification, and calibration practices of flow meters and their associated accessory instrumentation;
– simplified uncertainty calculations with examples to illustrate the methodology.
