Industrial process tomography is a non-invasive visualisation technique to obtain cross-sectional images of dynamic industrial processes. Electrical capacitance tomography (ECT) is the first developed and the most mature tomographic imaging technique used for industrial applications. Comparing with other tomographic techniques, it is relatively cheap, fast and safe. This paper describes the process of developing a portable ECT system in terms of sensor design, capacitance measuring circuit design, capacitance calibration and image reconstruction. Different image reconstruction algorithms were verified and compared.
