摘要

The magnetically inductive flowmeter (1) has first measuring electrode (3) which is produced from a first material (A) and the second measuring electrode (4) from a second material (C) that is different from the first material. The control and evaluation unit (12) determines the respective d.c. voltage fraction of the voltage. The d.c. voltage fraction of the voltage is captured at the two electrodes in relation to reference potentials and provides information that is specific to the medium using the o.k. voltage fraction.
