Abstract
The present disclosure relates to a method for operating a magneto-inductive flowmeter, wherein the magneto-inductive flowmeter has a measuring tube for conducting a flowable medium, at least two measurement electrodes for detecting a flow speed-based measurement voltage induced in the medium, and a magnetic field-generating device for generating a magnetic field which passes through the measuring tube, said magnetic field generating device having a coil. The method has the steps of applying a control voltage to the coil in order to generate a change in the coil current over time, and determining the change in the coil current over time in a change-over region, wherein the coil current is changed in the change-over region until a target coil current target is reached.
