Abstract:
1. A measuring system, for flowable, especially fluid, media, said measuring system comprising: a measuring transducer, through which a medium flows during operation, at least at times, and which generates primary signals influenced by at least one measured variable characterizing the flowing medium; and an evaluating circuit electrically coupled with said measuring transducer and processing primary signals delivered by said measuring transducer as measured values, said measuring transducer includes: at least one measuring tube, vibrating, at least at times, during operation and serving for conveying medium to be measured; an exciter mechanism including at least one oscillation exciter, acting on said at least one measuring tube for causing said at least one measuring tube to vibrate; and a sensor arrangement serving for registering oscillations of said at least one measuring tube, said sensor arrangement including: a first oscillation sensor, arranged on said at least one measuring tube, spaced from said at least one oscillation exciter, for delivering a first primary signal of said measuring transducer representing vibrations of said measuring tube; a second oscillation sensor, arranged on said at least one measuring tube, spaced from said first oscillation sensor, and spaced from said at least one oscillation exciter for delivering simultaneously with the first primary signal, a second primary signal of said measuring transducer representing vibrations of said measuring tube; a third oscillation sensor, arranged on said measuring tube, spaced both from said first and said second oscillation sensors and spaced from said at least one oscillation exciter, for delivering, a third primary signal of said measuring transducer representing vibrations of said measuring tube and a fourth oscillation sensor, arranged on said measuring tube, spaced from said first, second and third oscillation sensors and spaced from said at least one oscillation exciter, for delivering, a fourth primary signal of said measuring transducer representing vibrations of said measuring tube, wherein: said evaluating circuit is adapted to generate, by means of said first, second third, and fourth primary signals, a measured value, which represent, a mass flow rate, of medium flowing through said measuring transducer.
