Abstract

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