Abstract

A Coriolis mass flowmeter incorporates a measuring tube for guiding a flowing medium, a first oscillator for the oscillatory stimulation of the measuring tube, as well as a first oscillation sensor and a second oscillation sensor for picking up Coriolis oscillations of the measuring tube. The first oscillator, the first oscillation sensor and the second oscillation sensor are mutually spaced apart in the longitudinal direction of the measuring tube and the first oscillator is activated by an oscillation-stimulating control device. A third oscillation sensor is provided and positioned opposite the first oscillator at the same longitudinal distance of the measuring tube. Additionally or alternatively, a second oscillator and a third oscillator may be provided, with the second oscillator positioned opposite the first oscillation sensor and the third oscillator positioned opposite the second oscillation sensor, in each case at the same longitudinal distance on the measuring tube. All mutually opposite oscillators and oscillation sensors are of the same size, resulting in a “balanced” measuring tube while opening up various possibilities for improving the evaluation and control of the f…
