摘要： A method is disclosed for operating a flowmeter, such as an inductive flowmeter, in which a medium flows through a measuring tube, and an arrangement of electrodes are conductively connected to the medium. To determine a filling level in a simple and reliable manner, at least four electrodes are arranged in the measuring tube essentially in a half-circumferential region based on a cross section through the measuring tube. When at least one signal is fed in at one of the electrodes or at one of the electrode pairs, an electrical current is measured at an electrode or between an electrode pair. An electrical voltage is measured between at least one other electrode pair or with respect to a common connection to ground. When comparing measurements with two different electrode combinations, different voltage and current values are related to infer a diagnosis, such as a filling level in the tube, and/or an electrode coating, and/or an oblique installation, and/or a sedimentation at a bottom of the tube. The diagnosis can be used to correct a flow rate.

摘要： The disclosure relates to a method for measuring a flow rate, in particular in an inductive flowmeter, in which an electrical signal is applied to a measuring medium flowing in a measuring tube at electrodes, and the response function at measuring electrodes is determined as a measure of the flow rate, and to a corresponding flowmeter device. So that the flow effects of gas bubbles and/or particles in the measuring medium can be distinguished from other faults and the determination of the flow rate is thus more reliable, the disclosure proposes that, in order to detect gas bubbles and/or particles in the measuring medium, a magnetic and/or electric field is applied to the latter and the potential and/or current is/are read out at one or more electrodes, the signal profile A(t), together with its signal-to-noise component, is measured electronically as a function of the time, and a statistical evaluation is used to infer the existence of gas bubbles and/or particles.

摘要： The disclosure relates to a method for operation of a flow measurement device, and to a flow measurement device itself. In order in this case to record the conductivity of the medium or faults resulting from deposits by means of a measurement tube configuration in a technically simple manner, a total of at least 4 electrodes are arranged distributed on the circumference of the measurement tube, in the measurement tube. When a signal is fed in at one of the electrodes or at an electrode pair, an electric current is measured between one electrode pair, while an electrical voltage is measured between another electrode pair. An impedance value is determined from the two measured values, from which impedance value a conductivity of the medium is determined and/or in comparison of different conductivities or in comparison with historical values, it is deduced that there is a covering layer on the electrodes.
