Abstract
A magneto-inductive flow measurement device, comprises a means for producing a magnetic field with a self-inductance, wherein the means for producing the magnetic field comprises a coil arrangement; a means for sensing a measurement voltage induced in the flowable medium; an operating circuit, which is adapted to apply an operating signal on the coil arrangement, wherein the operating signal has operating signal parameters; a measuring circuit, which is adapted to determine a coil electrical current of the coil arrangement; a control circuit, which is adapted so to control at least one of the operating signal parameters that a function dependent on a self-induction value of the self-induction and a coil electrical current value of the coil electrical current does not differ from a predetermined, first desired value.
