Abstract
A magnetoinductive flow meter has an electromagnet unit which is mounted on an outside periphery of a measuring tube. The electromagnet unit can include magnetic flux-concentrating device and electric coils for generating a magnetic field which is oriented substantially perpendicular to the direction of flow of a measuring medium which flows through the measuring tube. The magnetic flux-concentrating device of the electromagnet unit can include ferrite pole cores each respectively associated with each one of the electric coils. A single magnet yoke composed of an electric sheet material can be connected to each ferrite pole core. The magnet yoke can surround the electric coils jointly in a clip-like manner.
