Measurement Methodology to Characterize Permittivity-Mass Concentration Relations of Aerated Bulk Materials

Capacitive flow meters have become widely used for flow measurements in pneumatic conveying systems. A crucial parameter for the determination of the mass flow rate is the mass concentration. Capacitive measurements are influenced by the effective permittivity of a particle-gas mixture within the sensor, which in turn depends on the mass concentration. Thus, the determination of the mass concentra...
