A magnetic-inductive flowmeter with a measuring tube for guiding an electrically conductive medium, a magnetic circuit device running outside the measuring tube for generating and guiding a magnetic field through the measuring tube, and two electrodes for tapping a measuring voltage induced in the medium. The magnetic circuit device has at least a first coil for generating the magnetic field and first and second pole piece plates, the magnetic field being formed between the pole piece plates, wherein the measuring tube is arranged between the two pole piece plates and wherein the electrodes are arranged on opposite sides of the measuring tube, an imaginary connecting line between the two electrodes running perpendicular to the direction of flow and perpendicular to the direction of the magnetic field. The magnetic field is fed into the pole piece plates by at least two feed-in regions per pole piece plate.

Magnetic-inductive flowmeter and magnetic circuit device

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.
