Abstract
A magnetic-inductive flow meter includes: a housing; a first and a second measurement electrode in galvanic contact with a flowing medium in a pipe; a magnetic field-generating device positioned in the housing and including a measurement circuit configured to determine a first measurement variable, and wherein measurement values of the first measurement variable are measured between two measurement electrodes or at a measurement electrode in relation to a reference potential; and an evaluation circuit configured to determine a Reynolds number and/or a kinematic viscosity value of the medium using measurement values of the first measurement variable and of a second measurement variable, which differs from the first measurement variable, wherein the measurement electrodes are positioned such that, during a test measurement, quotients of current measurement values of the first and of the second measurement variable correspond bijectively with the Reynolds number of the medium in the pipe.
