Fremgangsmåde til drift af en magnetisk induktiv flowmåler

摘要

Method for operating a magnetoinductive flowmeter in which a known current is applied between two measuring electrodes (2, 3) that are wetted by the medium flowing in a measurement pipe (1) or between a measurement electrode and an additional electrode (4, 5) that is contact with the medium flowing in the pipe. The resultant measurement voltage is used with the current to determine the resistance between the two electrodes.
