Abstract:
1. Magnetic-inductive flowmeter for measuring the rate of flow of a flowing medium, comprising: 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 for detecting and tapping a measurement voltage which has been induced in the flowing medium, wherein an electrically insulating cover layer provided at least partially over the inside of the measurement line, wherein the measurement electrodes are adapted for galvanically or capacitively tapping the measuring voltage and wherein the measurement electrodes are 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 up to just about over half of the periphery of the measurement line and are in direct electrically-conducting or galvanic contact with the flowing medium; and wherein the measurement electrodes are made of the same material or similar material as the cover layer and the material of the measurement electrodes has a much higher electrical conductivity than the material of the cover layer.
