14、 rotational movements are superimposed FC 2 m v FC Coriolis force m moving mass rotational velocity v radial velocity in rotating or oscillating system The amplitude of the Coriolis force depends on the moving mass m its velocity v in the system and thus on the mass flow Instead of a constant angula
15、r velocity the Promass sensor uses oscillation In the sensor two parallel measuring tubes containing flowing fluid oscillate in antiphase acting like a tuning fork The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations see illustration At zero flow in other
16、words when the fluid is at a standstill the two tubes oscillate in phase 1 Mass flow causes deceleration of the oscillation at the inlet of the tubes 2 and acceleration at the outlet 3 a0003385 The phase difference A B increases with increasing mass flow Electrodynamic sensors register the tube oscillations at the inlet and outlet System balance is ensured by the antiphase oscillation of the two measuring tubes The measuring principle operates independently of temperature pressure viscosity cond
