Abstract: A magneto inductive, flow measuring device comprising a measuring tube and at least one magnet system arranged on the measuring tube. The magnet system has two coil systems, which lie opposite one another on or in the measuring tube, and each coil system includes at least one pole shoe. A first of the two coil systems is connected via at least one flux return, sheet metal length with the second or an additional coil system, and wherein each of the at least two coil systems has at least two coils, which are arranged peripherally distributed relative to the measuring tube on the pole shoe.

Abstract: A magnetically inductive flow measuring probe comprises a housing that is adapted to be exposed to the medium; two measuring electrodes arranged in a housing end section for forming a galvanic contact with the medium and for sensing a voltage induced in the flowing medium; and a means for producing a magnetic field passing through the housing end section. The means includes a coil arrangement and a field guide body. The field guide body comprises two field guide body legs connected with a coil core, extending to a front section of the housing and adapted to serve as field guideback. Orthogonal projections of the measuring electrodes and the field guide body onto a cross sectional plane are disjoint.

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.
