scope:

This Standard applies to AC and pulsed-DC type industrial electromagnetic flowmeters with either wetted or non-wetted electrodes, and to the application of these flowmeters to the measurement of the volumetric flowrate of electrically conducting and electrically homogeneous liquids or slurries flowing in a completely filled closed conduit. It specifically does not apply to insertion or medical type electromagnetic flowmeters. It also does not cover applications of industrial flowmeters involving nonconductive liquids or highly conductive liquids (i.e., liquid metals).

This document contains a discussion of the theory and measurement technique of an electromagnetic flowmeter, a physical description of the various types available, application considerations, specifications as to what equipment markings should reside on the meter, and liquid calibration procedures.
