ABSTRACT:
A mass flow meter operating by the Coriolis principle includes a mechanical oscillating system having two straight measuring tubes which are clamped at both ends. In the center of the measuring tubes an oscillation exciter is disposed which sets the two measuring tubes into oppositely phased flexural oscillations. The mechanical oscillations are sensed by oscillation sensors which are arranged at equal distances on both sides of the oscillation exciter. The phase displacement of the sensed oscillations is a measure of the mass flow. The mechanical oscillating system is arranged axially in a support tube. For decoupling the mechanical oscillations from the support tube the mechanical oscillating system is freely suspended in the support tube at each end by an annular diaphragm. The entire mechanical oscillating system including the diaphragms preferably consists of titanium.
