METHOD FOR OPERATING A MAGNETIC-INDUCTIVE FLOWMETER AND MAGNETIC-INDUCTIVE FLOWMETER

原文（中国語）

A method for operating a magnetic-inductive flowmeter is provided. The magnetic-inductive flowmeter comprises at least one measuring tube with an inflow region, an outflow region, and a measuring region located between the inflow and outflow regions for performing a flowing medium through the flowmeter; At least one magnetic field generating device generates a magnetic field passing through the measuring tube in the measuring region substantially perpendicular to the direction of flow of the medium. At least one pair of measuring electrodes in the measuring region of the measuring tube taps an electrical voltage induced in the medium in the measuring tube. At least one control and evaluation unit which, in a flow measurement mode, determines a flow measurement value from the measured induced electrical voltage. In a fill level measuring mode, a measuring current is fed into the medium in the measuring tube via circuit electrodes.
