  • Publication number: 20240060804
    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.
