The Measurement Principle

The Rheonik RHM100 Coriolis Mass Flow Meter  has two measuring tubes. The oscillating system is driven by two controlled electromagnetic excitation coils. As liquids or gases flow through the oscillating omega tubes, the Coriolis force is created and causes a slight deflection of the two measuring tubes from their original shape.

The opposing tubes are referenced to each other and the changes in deflection are proportional to the mass flow rate. In practice, the referencing is done by attaching small pickup coils that generate sinusoidal voltages. The degree of deviation of the phase shift is directly proportional to the mass flow.
