摘要： A circuit for detecting faults in a magmeter system in which an electrically conductive fluid flows which is maintained at a reference potential. The circuit includes at least two electrodes in contact with the fluid. The electrode signals are conducted to the corresponding inputs of a measuring circuit. An alarm circuit is connected ahead of the measuring circuit. A difference in the magnitude of the values (+U.sub.S and -U.sub.S) of the electrode signals and/or non-symmetries in the noise content of the electrode signals and/or a disturbance in the high frequency signal (U.sub.G) in a loop which contains the electrodes and a high frequency producing generator causes an alarm to be activated.

摘要： A vortex flowmeter is disclosed, which includes, among other features, a closed measuring tube, through which a flowable medium that is to be quantitatively measured flows, the medium flowing against a disturbing element that is arranged in the measuring tube. A vibration sensor is arranged downstream in the direction of flow detecting the vortex frequency generated by the disturbing element. An electronic evaluation unit is disposed downstream of the vibration sensor converting it into an electric signal corresponding to the quantitative flow rate or volumetric flow rate. The relative position can be changed between the measuring tube and the disturbing element and/or the measuring tube and the vibration sensor in a signal-optimizing manner.

摘要： Disclosed is a method for diagnosing technical devices, especially pumps and valves, which are arranged within an installation used in the processing industry. According to said method, disturbance variables that affect the devices and influence the service life thereof are detected by means of sensory technology while the data of said disturbance variables is processed in a simulative manner in order to determine the expected service life of each device. Various maintenance instructions which are output along with the expected remaining trouble-free operating time of the industrial installation when a lower service life threshold value of one or several devices has been reached are stored in an expert unit.

摘要： The invention relates to a method for operating a measuring device, especially a flowmeter, according to the preamble of claim 1. The aim of the invention is to simplify inspection if the sensors have been correctly installed. For this purpose, the installation state is detected by the sensors themselves, i.e. by sensing a corresponding sensor value and comparing it with characteristic data. The result of comparison is electronically evaluated and automatically estimated whether the characteristic data obtained match the comparative data within at least a defined tolerance.

摘要： The invention relates to a method for monitoring a measurement device, in particular a flow measurement device, and to a measurement device itself. In order in this case to reliably preclude measurement errors resulting from incorrect installation, the invention proposes that a characteristic variable is calculated from a time series s(t) of the measurement signal of a measurement device and is compared with previously recorded reference values, with this being used as the basis to automatically generate a message as to whether the measurement device has been installed correctly or incorrectly.

摘要： Magneto-inductive flow measurement using a pulsed and/or reversing pulsed constant field wherein the measurement voltage which is induced by the flow, running transversely with respect to the magnetic field, of the measurement medium in the measurement tube of the magneto-inductive flowmeter is sampled in each clock time interval when the coil current is applied, even if the magnetic field has not yet reached its steady-state. Empirically determined correction values are used to correct the samples to the situation when measurements are carried out with a steady-state magnetic field. Calibration measured values can be recorded in a steady-state magnetic field from time to time, in order to check and, if required, to correct the correction factors. The coil current can be switched at frequencies which alternate with one another in time, the number of periods of the mutually alternating period sequences being varied in an irregular manner.
