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.

Abstract: A magnetic-inductive flow measuring device includes measuring electrodes, each having an end face including a planar annular edge region surrounding a center region, each annular edge region configured to seat against a sealing surface of an inner mold such that the center region of the end face does not contact the inner mold during the injection molding of a measuring tube body. A method for manufacturing the magnetic-inductive flow measuring device includes steps of providing and positioning an inner mold, an outer mold and two measuring electrodes, where each annular edge region of each measuring electrode seats against its corresponding sealing surface of the inner mold such that the center region of the measuring electrode protrudes into the corresponding recess of the inner mold without contacting the inner mold.
