    FC7x0 Measuring principle and flow meter design Measuring principle 6 Measuring principle and flow meter design 6.1 Measuring principle The measuring principle is based on the generation of Coriolis forces. For this purpose, a driver system (E) excites the two measuring tubes (M1, M2) in their first resonance frequency.
  • Page 23 FC7x0 Measuring principle and flow meter design Measuring principle The small deformation overlying the fundamental vibration is recorded by means of pick- offs (S1, S2) attached at suitable measuring tube locations. The resulting phase shift Δ φ between the output signals of pick-offs S1 and S2 is proportional to the mass flow. The output signals generated are further processed in a transmitter.
