Abstract

An experimental method for evaluating the performance of capacitance tomographic flow imaging systems is described. Criteria are defined to describe the performance of these systems, namely spatial and permittivity resolution, accuracy (system errors) and signal to noise ratio. Static physical models simulating typical flow distribution patterns are used as standard test objects and The criteria are quantified by comparing the reconstructed images with the standards. Systems with 8 and 12 electrodes have been tested and the results compared to show the improvement obtained with the increased number of electrodes
