What is ISO 20456 — Electromagnetic flowmeters for conductive liquids about?
ISO 20456 is an international standard that focuses on electromagnetic flowmeters for conductive liquids. ISO 20456 applies to industrial electromagnetic flowmeters used for the measurement of the flow rate of a conductive liquid in a closed conduit running full.
ISO 20456 covers flowmeter types utilizing both alternating current (AC) and pulsed direct current (DC) circuits to drive the field coils and meters running from a mains power supply and those operating from batteries or other sources of power.
