The measuring system operates on the Coriolis principle. The Coriolis force acts on an object travelling in a straight‑line path within a rotating system. Fc = 2 · ∆m (ν · ω) Fc = Coriolis force ∆m = mass of the moving object ω = angular velocity ν = radial velocity of the object in the rotating or oscillating system The magnitude of the Coriolis force depends on the mass \(\Delta m\) of the moving object and its radial velocity v, i.e. the mass flow rate. Instead of a rotating system with constant angular velocity \(\omega\), the sensor uses oscillating measuring tubes.Fluid flows through the sensor. Two parallel measuring tubes inside the sensor oscillate in antiphase, comparable to a tuning fork. The Coriolis force generated in the measuring tubes produces a phase shift of tube oscillation: • At zero flow (fluid stationary), the two measuring tubes oscillate in‑phase with no phase difference. • Mass flow accelerates oscillation at the measuring‑tube inlet and decelerates oscillation at the outlet, creating a phase shift.The higher the mass flow rate, the larger the phase shift. Electromagnetic phase sensors register the oscillation phase at the inlet and outlet of the measuring tubes. Antiphase oscillation of the two measuring tubes ensures system balance. The measuring principle is completely independent of temperature, pressure, viscosity, electrical conductivity and fluid properties.
