Measuring instrument (except for measuring time)

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.
