A magnetic-inductive flowmeter, having a plurality of functional units and a housing common to all the functional units, wherein each functional unit has a measuring tube, a magnetic field generating device, and two measuring electrodes, and wherein a virtual connecting line of the two measuring electrodes extends at least substantially at right angles to the direction of the magnetic field penetrating the measuring tube at right angles to the longitudinal axis of the measuring tube. In the housing, there is a common medium feed connection for the measuring tubes of all the functional units, a common power supply for the magnetic field generating device of all the functional units, and a common evaluation unit for the measuring electrodes of all the functional units. The magnetic field generating device has a field coil adjoined on both sides by a magnetic field guide part extending at right angles to the coil axis.

Magnetic-inductive flow meter device having a plurality of flowmeter units, power supply and evaluation units provided in a common housing

A magnetoinductive flowmeter includes a measuring tube, a magnetic field device serving to generate and guide a magnetic field at least part of which permeates the measuring tube, and two electrodes for collecting a voltage induced in a medium as it flows through the measuring tube. The electrodes are so positioned, without connection to the magnetic field device, that their longitudinal axes extend at an angle diverging from zero relative to the direction of the voltage induction. In this uncomplicated fashion, a large effective electrode surface is made available for collecting the voltage induced in the medium. A method for producing the flowmeter is also described.
