Abstract

This paper describes a non-invasive approach for a combined flow profile and velocity measurement of powdery solids and fluids. The measurement is based on Electrical Capacitance Tomography (ECT) techniques, where disturbances in terms of aluminum tracer particles are detected by monitoring capacitance changes caused by the metal tracers. The proposed algorithm for the localization of disturbances forms the basis for a later cross-correlation of layer images and for velocity and profile measurement consequently.
