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： Measuring transducer of vibration-type for a fluid flowing in a pipeline. The measuring transducer includes, in such case, a curved measuring tube for conveying the fluid, a counteroscillator having two counteroscillator arms, which are arranged on both sides of the measuring tube, and which, in each case, essentially follow the curve of the measuring tube, and which are coupled to one another in such a manner, that, during operation, they oscillate in phase with one another, and which are affixed to the measuring tube on the inlet side and outlet sides for forming corresponding coupling zones. The measuring transducer also includes an exciter mechanism, via which, during operation, the measuring tube and the counteroscillator are excitable to oscillations of opposite phase to one another. In such case, the counteroscillator arms are formed from a different material than the measuring tube, and the material of the counteroscillator arms has a thermal expansion coefficient essentially equal to that of the material of the measuring tube.
