  • Patent number: 9970795
    Abstract: A method for flow measurement using a magnetic-inductive flowmeter with a measuring tube and magnetic field generator that allows for detection of a zero flow error is achieved in that the measuring tube is filled with a first medium, the strength of the magnetic field is measured over a first measuring interval and a derivative with respect to time of the measured strength of the magnetic field is determined for the first measuring interval, that a second medium is made to flow through the measuring tube, the strength of the magnetic field is measured over a second measuring interval and a derivative with respect to time of the measured strength of the magnetic field is determined for the second measuring interval, that a deviation of the derivative for the second measuring interval from the derivative for the first measuring interval is determined, and assigned to a zero flow error.
