Abstract: A magneto-inductive flow measurement device for determining a flow-rate-dependent measured variable for a flowable medium, comprises a device for producing a magnetic field, the device for producing the magnetic field comprising a coil arrangement; a device for tapping off a measurement voltage induced in the flowable medium, in particular by means of two preferably diametrically arranged measurement electrodes; an operating circuit configured to apply an operating signal, in particular a voltage signal, to the coil arrangement, the operating signal having operating signal parameters; and a controller circuit configured to control at least one of the operating signal parameters in such a way that a controlled variable does not differ from a predefined setpoint value, the setpoint value comprising a magnetic field energy of proportional magnitude.
