Zusammenfassung: | A magnetic-inductive flow meter includes: a measuring tube for conducting a flowable medium, the measuring tube having a wall; at least three measuring electrodes arranged in the wall to form a galvanic contact with the flowing medium; a magnetic field-generating device for generating a magnetic field that passes through the medium; a measuring circuit designed to ascertain at least one first measurement variable, wherein measured values of the first measurement variable are ascertained at a first measuring electrode pair; and an analysis circuit designed to ascertain a Reynolds number and/or a kinematic viscosity value of the medium in the measuring tube using measured values for the first measurement variable and a second measurement variable, which differs from the first measurement variable, the measured values of the second measurement variable being ascertained at a second measuring electrode pair. |
