A flow measurement device and a method of manufacturing a flow measurement device having a measurement tube made from plastic or at least a plastic liner are provided. According to an exemplary embodiment, the measurement tube can be fabricated from plastic in an injection molding apparatus. Thereafter, electrical components of the measurement tube, such as electrodes and a coil holder, for example, can be concomitantly injection molded in a common, separate injection molding process. The electrical components can there be installed easier and more reliably in position.

Method of manufacturing a flow measurement device

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.
