摘要： The flowmeter comprises a flow sensor with a flow tube, two electrodes, and two field coils traversed by a first excitation current and a second excitation current, respectively, as well as control and evaluation electronics. The method serves to generate an error signal when the uniform turbulence in the liquid to be measured is disturbed. There are four quarter cycles. During each quarter cycle, a voltage is derived from the electrodes, and from these voltages, a first and a second voltage difference and a quotient using the first and the second voltage differences are formed. The latter is determined during calibration under uniformly turbulent flow conditions, and stored. In operation, values of the quotient are continuously formed and compared with the stored quotient; in case of deviations, an alarm is triggered and/or the volumetric flow rate signal represented by the first voltage difference is corrected.

摘要： An installed hardware of a measuring field device includes at least one transducer reacting during operation to a chemical and/or physical, measured variable of a pourable and/or flowable medium, especially a pourable or flowable bulk good, liquid, gas or the like, as well as a microcomputer communicating during operation with the transducer. The field device is first installed by means of the transducer on, and/or in a process vessel serving for conveying and/or holding pourable and/or flowable media for forming a process measuring point. Thereafter, the microcomputer is booted and a basic software held in a memory provided within the field device for providing, at least in part, basic functionalities of the field device is activated in such a manner that the basic software is executable by means of the microcomputer so that, in the interaction of basic software and hardware installed in the field device, the basic functionalities of the field device are available. Additionally, at least one initial identification parameter set held at least temporarily in the field device and at least approximately identifying the process measuring point is transferred, with application of basic software executed in the microcomputer, to a data processing system superordinated externally of the field device, and at least one upgrade software providing custom functionalities for the field measuring device going beyond the basic functionalities and held in a second memory, is selected from an ensemble of software products, taking into consideration the at least one, initial identification parameter set. A selected upgrade software fitted to the process measuring point is then transferred into a third memory provided within the field measuring device and then activated in such a manner that it is executable by means of the microcomputer, so that, in interaction of upgrade software and hardware installed in the field device, custom functionalities of the field measuring device are available.

摘要： A flow meter includes a measuring tube for conveying a fluid to be measured and a magnetic field system, which has at least one field coil, through which an exciter current (IM) flows, at least at times, for producing a magnetic field passing through the fluid at least partly perpendicularly to a stream direction. In the method, the voltage (UH) instantaneously driving the exciter current (IM) is changed at a second point in time, t2, from the second voltage level, Udrv, to a third voltage level, Ushort, especially to a third voltage level which is constant or controlled to be constant, in order to achieve a sinking of the electrical current strength of the exciter current (IM) instantaneously flowing in the at least one field coil from the maximum current value, Im, to an electrical current end value, Iczu, especially a constant end value, predetermined for the exciter current (IM) In such case, the third voltage level, Ushort, is chosen smaller than the second voltage level, Urev. For determining a third point in time, t3, which corresponds to the reaching of the electrical current end value, Ic, the exciter current IM is registered, at least at times. Based on this, a first time constant, Tshort, for the magnetic field system is determined, which corresponds to a time span, t3−t2, lying between the second point in time, t2, and the third point in time, t3, and/or a second time constant, Trev+Tshort, for the magnetic field system, which corresponds to a time span, t3−t1, lying between the first point in time, t1, and the third point in time, t3. For determining a diagnosis value representing an instantaneous operating state of the flow meter, the determined first time constant, Tshort, is then compared with a predetermined first reference value, T1ref, and/or the determined second time constant, Trev+Tshort, is compared with a predetermined second reference value, T2ref.
