| Abstract: | In the past years, almost all electrical capacitance tomography (ECT) systems are devised for circular pipelines, but in many industrial applications such as circulating fluidised beds, ECT for square sensors are required.A model of square sensor structure with our new development kit is introduced, and the sensitivity distribution by using finite element method (FEM) is computed in this paper. The image reconstruction is also implemented with LBP, LBP Thresholded and Simultaneous Iterative Reconstruction Technique (SIRT) based on a 12 Electrode Square ECT. The simulation results are promising |
