摘要: The invention relates to a method and a device for operating a flow meter, in particular magnetically inductive flow meters but also capacitive meters, as well as those which comprise electrodes which can be used in order to feed a signal into the fluid to be measured, according to the preamble of patent claim 1. In order to record a diagnosis both of the meter per se, but also of the changes in the constitution or consistency of the flowing medium at any time during measurement operation, according to the invention a signal E1i in the form of a current or a voltage is applied to at least one electrode and, at another electrode E2i which does not receive the signal or is not currently activated, impedances are determined and/or voltage(s) and/or current(s) are measured, wherein these values are set in comparison/ratio with previous values and the status/a perturbation of the device and/or of the measurement medium is deduced first qualitatively and then quantitatively therefrom.

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: 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.
