A magnetic-inductive flow-through measurement
system, having a measuring tube for an
electrically conductive medium, a
magnetic field generating device for generating a
magnetic field running at least perpendicular to the longitudinal axis of the measuring tube, at least two measuring electrodes which tap the measurement
voltage induced in the
electrically conductive medium, and an evaluation unit, wherein the measuring electrodes have measuring contact which are accessible externally on the measuring tube, and the measuring tube together with the measuring electrodes form a first functional unit, and counter-contacts corresponding to the measuring contacts, the
magnetic field generating device and the evaluation unit form a second functional unit in a measurement
system housing. The measuring electrodes and the corresponding counter-contacts corresponding are arranged in such a way, that the measuring contacts can be brought into
electrically conductive contact with the counter-contacts by a movement running substantially perpendicular to the magnetic field direction.
