ABSTRACT:
A magnetic-inductive flowmeter for measuring the rate of flow of a flowing medium, having a measurement line, a magnetic field generating means for generating a magnetic field which at least partially penetrates the measurement line, and two measurement electrodes, and an electrically insulating cover layer provided at least partially over the inside of the measurement line, the measurement electrodes being strip-shaped having a length in a peripheral direction of the measurement line of between about just under one fourth of the periphery of the measurement line to about just over half the periphery of the measurement line and being exposed to the interior of the measurement line to be in direct, contact with the flowing medium. The measurement electrodes can be made of the same material or a similar material as the cover layer, but having a much higher electrical conductivity than the material of the cover layer.
