Flow property determination in homogeneous media by means of perturbation injection

This paper describes a combined measurement of material density and particle velocity for dense bulk solids flow in pipelines. The measurement is based on electrical capacitance tomography techniques, enhanced by an insertion of artificial disturbances upstream the capacitive sensor. Obtained material velocity and material density allow for the estimation of the mass flow even for totally homogenous material flow. The applicability of this principle for parameter estimation is discussed, presenting theoretical considerations as well as preliminary measurement results
