A device and a method for its manufacture, for magnetic-inductive measurement of the quantity of mixture flowing through a pipeline into which the device has been incorporated. The device includes a housing having a measuring tube with an electrically insulating lining therein. The lining substantially consists of wear-resistant, insulating ceramic material in the form of tiles applied on a layer of plastic material having a thickness between 3 and 10 mm. The joints between the tiles are filled with plastic material. The housing contains magnetic coils. A pair of electrodes are mounted in the measuring tube and extend through the wall of the measuring tube and are insulated in relation to it. Within the housing, the electrodes are connected to lines leading to measuring members for measuring the voltage difference generated in the flowing medium by the magnetic field of the magnetic coils.
