The measuring principle is based on the controlled generation of Coriolis forces. These forces are always present when both translational and rotational movements are superimposed.FC = 2 · Δm (v · ω)FC = Coriolis forceΔm = moving massω = rotational velocityv = radial velocity in rotating or oscillating systemThe amplitude of the Coriolis force depends on the moving mass Δm, its velocity v in the system, and thus onthe mass flow. Instead of a constant angular velocity ω, the Promass sensor uses oscillation.In the sensor, two parallel measuring tubes containing flowing fluid oscillate in antiphase, acting like a tuningfork. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations
