Defines principle and main design features of industrial electromagnetic flowmeters for measuring flowrate of a conductive liquid in a closed conduit running full. Deals with installation, operation, performance and calibration. Does not define safety requirements relating to hazardous environmental usage of the meter nor measurement of magnetically permeable slurries, liquid metals nor usage in medical applications. Covers both a.c. and pulsed d.c. versions.
