1. A magnetically inductive flow measuring probe for insertion into an opening of a pipeline flowed through by a flowable medium and for ascertaining a flow-velocity-dependent measured variable of a flowable medium, the magnetically inductive flow measuring probe comprising:
a housing that is adapted to be exposed to the medium, the housing having:
a housing end section; and
a housing case that encloses a housing interior;
two measuring electrodes arranged in the housing end section for forming a galvanic contact with the medium and for sensing a voltage induced in the flowing medium, wherein each of the two measuring electrodes has a measuring electrode contact element protruding inwardly into the housing interior, wherein the two measuring electrode contact elements are arranged such that a housing longitudinal plane extends through the two measuring electrode contact elements;
a means for producing a magnetic field that passes through the housing end section, wherein the means for producing the magnetic field is arranged in the housing interior and includes a coil arrangement and a field guide body, wherein the coil arrangement includes an opening, and the field guide body includes a coil core that extends through the opening in the coil arrangement,
wherein the field guide body includes two field guide body legs connected with the coil core and extending to a front section of the housing and adapted to serve as a field guideback,
wherein orthogonal projections of the measuring electrodes and the field guide body onto a cross sectional plane perpendicular to a longitudinal axis of the housing are disjoint.
