摘要： The invention relates to a method for operating a magnetic-inductive flow meter having a measuring tube, wherein an at least partially electrically conductive measuring fluid flows through the measuring tube, wherein a clocked magnetic field is produced for determining the flow rate by means of at least one coil arrangement, said magnetic field at least partially penetrating the measuring fluid, wherein the magnetic field is produced by an energizing current that flows through the coil arrangement, wherein the magnetic field is operated by at least a first pulse, wherein, in the case that the coil arrangement is free of the energizing current, an electrical potential difference between the measuring fluid and a reference potential is tapped by means of at least one first measurement electrode communicating with the measuring fluid, wherein the potential difference is compared to a specified reference value and wherein, in the case of a deviation of the potential difference from the reference value under a specified threshold value, the magnetic field is operated by at least one second pulse, reduced compared to the first pulse, for determination of the flow rate.

摘要： The invention relates to an electronic measuring device for determining a potential difference (Ʌφ12) between a first measuring electrode having an electrical potential (φ12) and a second measuring electrode having an electrical potential (φ2). The electronic measuring device thereby comprises a reference electrode (GRN) having a reference potential (φRef), an input circuit having two circuit inputs that can be connected to the first and/or the second measuring electrode, two signal voltage outlets, a compensation circuit having a first compensation voltage outlet and a second compensation voltage outlet. Said electronic measuring device further comprises a control signal inlet and, for generating a digital voltage measurement signal (U
D ), a measurement and control circuit having two signal voltage inlets respectively connected to one of the signal voltage outlets of the input circuit, two signal voltage inlets, each electrically connected to one of the compensation voltage outlets of the compensation circuit, and a compensation control outlet connected to the control signal inlet of the compensation circuit. The compensation circuit is configured to provide a compensation voltage (U
C1 ), that is, an adjustable direct-current voltage relative to the reference potential, at the first compensation voltage outlet, and to provide a compensation voltage (U
C2 ), that is, a direct-current voltage relative to the reference potential, at the second compensation voltage outlet. The compensation circuit is further provided with at least two operating modes that can be selected by way of a compensation control signal, which can be placed at the control signal inlet. In a first operating mode, the compensation voltage (U
C1 ) is set to a specified voltage value, U
C11 , and in a second operating mode, the compensation voltage (U
C1 ) is set to a specified voltage value, U
C12 . The measurement and control circuit, on the other hand, is configured to provide a compensation control signal at the compensation control outlet for selecting one of the selectable operating modes of the compensation circuit.
