Abstract: A magneto-inductive flow measuring device for ascertaining flow of a measured medium through a measuring tube having a measuring tube axis, comprising: at least a first coil component having a coil body for accommodating a coil core of a coil. The coil is wound on the coil body and the coil core is arranged in a first passageway of the coil body with a longitudinal axis of the coil core coaxial with the coil. At least two cable strands are arranged between the coil core and the coil body, wherein the cable strands serve for tapping the signal of two or more measuring electrodes arranged on the measuring tube. The cable strands extend within the coil component essentially along a cutting plane, which extends perpendicular to the measuring tube axis.

Abstract: The present disclosure relates to a magnetic-inductive flow meter including a measuring pipe having a measuring pipe body which electrically insulates portions thereof. A device generates a magnetic field that penetrates the measuring pipe body and detects an induced voltage in the medium, which is a function of a velocity of flow. A monitoring device detects damage to the measuring pipe body and comprises at least one electrically conductive conductor. The conductor is separated from the measuring pipe volume by a region of the measuring pipe body when the measuring pipe body is intact. The monitoring device comprises a measuring circuit electrically connected to the conductor and is designed to measure values of a measured variable which is dependent on an impedance of the conductor. The measuring circuit then compares each of the measured values with a reference value or a target value range.
