Abstract
A magnetic-inductive flow meter with a measuring tube () made of metal, which is flowed through by a medium () which has a minimum electrical conductivity and is permeated by a magnetic field generated by means of an arrangement of magnets (), in the region of which field at least two measuring electrodes () arranged diametrically on the measuring tube () are provided for sensing the inductively generated measuring voltage, the metal measuring tube () being provided with an electrically insulating inner layer () and an electrically conductive grounding disk () being arranged at the end face for grounding the medium flowing through the measuring tube (), which disk is connected to ground via the measuring tube, the grounding disk (') consisting of an electrically conductive plastic which comes to lie in sealing contact directly against the end face () of the measuring tube () in order to be connected to ground by the direct contact.
