These recommendations cover volumetric turbine flowmeters having an electrical output. The flowmeters are used to measure either flow rate or quantity of liquids, and can be either self-generating or modulating. Their use in cryogenic fluids will require special considerations, which are not fully described herein.
Purpose
This document establishes the following for turbine flowmeters, especially those 2-inch diameter and smaller.
Recommended minimum information to be specified in ordering.
Recommended acceptance and qualification test methods including calibration techniques.
Uniform terminology and drawing symbols.
Recommended installation techniques.
