Abstract

A method for controlling coil current of a magneto inductive, flow measuring device with a first value representing an overvoltage UO and a second value representing a holding voltage UH, wherein the first value is greater than the second value, characterized by steps as follows: setting a first switching point IS for the electrical current level, up to which a coil should be supplied with the overvoltage UO; applying an overvoltage UO until the electrical current level rises to the switching point IS set for the electrical current level; switching from the overvoltage UO to the holding voltage UH, in order to hold the electrical current level at a constant electrical current end value IH. Also intended is a magneto inductive, flow measuring device.
