METHOD FOR OPERATING A MAGNETIC/INDUCTIVE FLOW METER AND, MAGNETIC/INDUCTIVE METER

摘要

The invention relates to a method (100) for operating a magnetic/inductive flow meter for measuring the flow rate or the volumetric flow of a medium in a measuring tube (10) and to such a flow meter, wherein the medium is acted upon by magnetic fields of different polarity and field strength, wherein the alternation between magnetic fields causes a voltage pulse in the medium, wherein a voltage pulse during a phase without a magnetic field is used for calculation of a correction of an electrode voltage characteristic.
