1. A magnetically inductive flow meter, the flow meter comprising:
a measuring tube including a measuring tube wall, which includes an electrically insulating surface made of a first material; and
an electrode including an electrode end surface configured for tapping off a measuring signal in a measuring medium and an electrode shank, which extends through an opening in the measuring tube wall along an electrode axis, wherein the electrode includes a stop that projects from the electrode shank, the stop including a stop surface structured to limit the displaceability of the electrode along the electrode axis and relative to the measuring tube wall,
wherein the electrode includes an electrically insulating coating on at least that portion of the electrode shank which is disposed within the opening in the measuring tube wall and on at least a portion of the stop surface, and wherein the material of the coating has a Shore hardness that is lower than the Shore hardness of the first material.
