A New Method for Mass Flow Measurement Based on Acoustic Damping of a Rheologic Medium

It is shown by investigation that when a suitable structure of the electromechanical system and a suitable vibrating mode are chosen, the acoustic vibrating damping in relation to the density, velocity and mass flow of a fluid can be obtained. By employing the principle of the electromechanical energy conversion, deterministic signals can be acquired at the electric driving terminal so that a new way of making an overall measurement of multiple parameters of the mass flow and the mixed phase fluid is found. The measuring principle, the structure and mathematical model of the device are described.
