Abstract
A magnetic-inductive flow meter with at least one measuring tube for through flow of an electrically conductive medium, with a magnetic field generating apparatus for generating an alternating magnetic field which runs at least also perpendicular to the longitudinal axis of the measuring tube, with at least two measuring electrodes which especially contact the medium and with an evaluation circuit, the magnetic field generating apparatus having at least one field coil and one coil power supply. Because the measuring electrode circuit, therefore the electrical circuit to which the measuring electrodes belong is monitored by a crosstalk voltage indicator of the evaluation circuit which is active in an operating state when an electrically conductive medium is not flowing through the measuring tube, whether the measuring electrode circuit is serviceable can be derived from the crosstalk voltage.
