Abstract
A magnetoinductive flowmeter incorporates a measuring tube, a magnet serving to generate a periodically alternating magnetic field that extends in a direction at least essentially perpendicular to the axis of the measuring tube, and two measuring electrodes positioned along a connecting line that extends in a direction at least essentially perpendicular to the axis of the measuring tube and to the vector of the magnetic field. An output device is provided by means of which a value for the constant-voltage component of the voltage collected at one or both of the measuring electrodes and differentiated from a reference potential is displayed to the user and/or is made available to the user for further processing. An equivalent flow-measuring process is also described.
