API MPMS CHAPTER 14.13

Die Annotation des Normtextes API MPMS CHAPTER 14.13 :

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. See more
