Mass flow (gas): -0.35 %
Density (liquid): -0.0005 g/cm3

Measuring principle: 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.

The amplitude of the Coriolis force depends on the moving mass, its velocity in the system, and thus on the mass flow. Instead of a constant angular velocity, the Promass sensor uses oscillation. The measuring tubes through which the measured material flows are brought into oscillation. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations.

• At zero flow, in other words when the fluid is at a standstill, the two tubes oscillate in phase.
• Mass flow causes deceleration of the oscillation at the inlet of the tubes and acceleration at the outlet.

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, conductivity and flow profile.
