Describes the principle and main design features of industrial electromagnetic flowmeters for the measurement of flow-rate of a conductive liquid in a closed conduit running full. Covers their operation, installation, calibration and performance. Does not specify safety requirements in relation to hazardous environmental usage of the meter, nor does it apply to the measurement of magnetically permeable slurries, usage in medical applications nor liquid metals. Covers flowmeter types in both a.c. and pulsed d.c. versions. Coverage includes definitions, equipment marking, and symbols and units. Also contains annexes and diagrams.
