scope:

This Standard is applicable to industrial electromagnetic flowmeters and their application in the measurement of liquid flow. The electromagnetic flowmeters covered by this Standard utilize an alternating electrical current (AC) or pulsed direct-current (pulsed-DC) to generate a magnetic field in electrically conductive and electrically-homogeneous liquids or slurries flowing in a completely filled, closed conduit.

This Standard specifically does not cover insertion-type electromagnetic flowmeters, meters used to measure flow in partially filled pipe, or those used in surgical, therapeutic, or other health and medical applications. It also does not cover applications of industrial flowmeters involving nonconductive liquids or highly conductive liquids (e.g., liquid metals).
