Abstract

ÜHSÜÜSÜHHA method for controlling the coil current of a magnetoinductive flowmeter with a first value representing an overvoltage U and a second value representing a holding voltage U wherein the first value is greater than the second value characterized by the following steps of: A setting a first switching point I for the current intensity up to which a coil is intended to be supplied with the overvoltage U; B applying an overvoltage U until the current intensity rises to the currently set switching point I of the current intensity; C changing over from the overvoltage U to the holding voltage U in order to keep the current intensity at a constant final current value I and a magnetoinductive flowmeter.
