摘要： A medium to be measured is allowed to flow through a measuring tube of a flow meter and a magnetic field passing at least sectionally with a time-varying intensity through the medium in the measuring tube is produced in such a manner that a measurement voltage is induced at least at times, especially in a clocked manner, in the medium. The measurement voltage induced in the medium is tapped, at least at times, by means of an electrode pair formed by first and second measuring electrodes for producing an analog measurement signal corresponding with the measurement voltage, and a flow-type of the medium located in the measuring tube, as determined by an instantaneous flow profile and/or an instantaneous composition of the flowing medium, is ascertained with application of a digital signal representing the at least one measurement signal. Starting on the basis that the measurement signal has a wanted-portion corresponding essentially with an instantaneous flow velocity of the medium and a noise portion influenced at least partially by existent disturbances in the flowing medium, ascertained are: a noise spectrum of the measurement signal corresponding with the noise portion; and, with application at least of a part of the noise spectrum, a state value signaling, at least qualitatively, at least one flow-type present in the measuring tube.
