Abstract: A method for operating a magnetic inductive flowmeter wherein the flowmeter includes a measuring tube for guiding a flowable medium; at least two measuring electrodes for detecting a measurement voltage which is dependent on the flow velocity and induced in the medium; and a magnetic field-generating device having a coil system with at least one coil for generating a magnetic field passing through the measuring tube, includes determining a deviation σ of a reactance of the coil system or a deviation σ of a variable dependent on the reactance of the coil system from a desired value. Also disclosed is a magnetic inductive flowmeter.
