摘要： A measuring system comprises: a measuring transducer; transmitter electronics; at least one measuring tube; and at least one oscillation exciter. The transmitter electronics delivers a driver signal for the at least one oscillation exciter, and for feeding electrical, excitation power into the at least one oscillation exciter. The driver signal, has a sinusoidal signal component which corresponds to an instantaneous eigenfrequency, and in which the at least one measuring tube can execute, or executes, eigenoscillations about a resting position. The eigenoscillations have an oscillation node and in the region of the wanted, oscillatory length exactly one oscillatory antinode. The driver signal has, a sinusoidal signal component with a signal frequency, which deviates from each instantaneous eigenfrequency of each natural mode of oscillation of the at least one measuring tube, in each case, by more than 1 Hz and/or by more than 1% of said eigenfrequency.

摘要： A method for detecting plugging of a measuring tube. Heat is supplied to a medium conveyed in a first measuring tube by means of at least one heating element, or heat is removed from the medium conveyed in a first measuring tube by means of at least one cooling element. At least one temperature sensor, which is thermally coupled to the medium conveyed in the first measuring tube, temperature is registered. Additionally, a first comparison variable, which is characteristic for heat transport by the medium in the first measuring tube, is determined based on the supplying of heat or removing of heat, as well as on the temperature registering, and this comparison variable is compared with a reference variable. Plugging of at least one measuring tube of the measuring transducer is detected if the first comparison variable deviates from the reference variable by more than a limit value.

摘要： A method for detecting complete or partial plugging of a measuring tube of a Coriolis flow measuring device, which is insertable into a pipeline, and which has a measuring transducer of the vibration type having at least two measuring tubes connected for parallel flow. The method includes, in such case, the steps of measuring a subset flow occurring in a subset of the measuring tubes, and comparing a subset flow value obtained from this measurement with a reference value to be expected for this subset. The reference value is, in such case, determined from a total mass flow determined in the context of a Coriolis mass flow measuring. Additionally, the method includes the step of detecting plugging of at least one measuring tube of the measuring transducer, if the subset flow value deviates from the reference value by more than a limit value.

摘要： An inline measuring device comprises a vibratory-type transducer and a measuring device electronics electrically coupled with the vibratory-type transducer. The vibratory-type transducer includes at least one measuring tube being inserted into the course of a pipeline and serving for conducting a mixture to be measured. An exciter arrangement acting on the measuring tube for causing the at least one measuring tube to vibrate and a sensor arrangement sensing vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers an excitation current driving the exciter arrangement. Further, the inline measuring device electronics is adapted to produce a measured value representing the physical, measured quantity of the mixture to be measured. Therefor, the measuring device electronics estimates from the excitation current and from said at least one oscillation measurement signal a Coriolis coupling coefficient. This Coriolis coupling coefficient corresponds with an instantaneous coupling between a first natural eigenmode of the measuring tube currently driven by the exciter arrangement and a second natural eigenmode of said measurement tube. In this second eigenmode the measurement tube has an eigenform corresponding with a mode of vibration caused by Coriolis forces induced in the flowing mixture. Due to a variation of a concentration of at least one of a component of the mixture the Coriolis coupling coefficient varies in time.

摘要： To conduct a fluid, the transducer has a flow tube which in operation is vibrated by an excitation assembly and whose inlet-side and outlet-side vibrations are sensed by means of a sensor arrangement. To produce shear forces in the fluid, the flow tube is at least intermittently excited into torsional vibrations about a longitudinal flow-tube axis. The transducer further comprises a torsional vibration absorber which is fixed to the flow tube and which in operation covibrates with the torsionally vibrating flow tube, thus producing reactive torques which at least partially balance torques developed in the vibrating flow tube. One of the advantages of the transducer disclosed is that it is dynamically balanced to a large extent even in the face of variations in fluid density or viscosity.
