A measuring tube for insertion in a measuring tube receptacle of a magnetic-inductive flowmeter and for guiding a medium, with two electrodes for tapping a voltage induced in the medium, wherein the electrodes each extend at least from a medium contact area to a connecting contact area on one end for connection to an evaluating unit. The electrodes are arranged on both sides of the measuring tube in an electrode plane situated perpendicularly on the longitudinal axis of the measuring tube and the electrodes extend parallel to one another and tangential to the measuring tube. The connecting contact areas on the ends of both electrodes are arranged on one side of a reference plane, which is situated perpendicularly on the electrode plane, and wherein the medium contact areas are located at least partially in the reference plane.

Measuring tube for insertion in a measuring tube receptacle of a magnetic-inductive flowmeter and a magnetic-inductive flowmeter

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.

Magneto-inductive flow-measuring system

A measuring tube for magneto-inductive flowmeter systems, having a measuring tube for the flow of an electrically conductive medium and a magnetic field generating device for generating a magnetic field, at least two measuring electrodes which tap the measurement voltage induced in the electrically conductive medium and preferably an evaluation unit. The measuring electrodes have externally accessible measuring contacts, wherein the measuring tube forms a first functional unit with the measuring electrodes, and mating contacts corresponding to the measuring contacts of the measuring electrodes, the magnetic field generating device and an evaluation unit, if present, form a second functional unit. The measuring contacts of the measuring electrodes are provided on the measuring tube in such a manner that they can be brought into electrically conductive contact with the mating contacts by a movement which runs substantially perpendicular to the direction of the magnetic field and is substantially only translational.
