Abstract :
Capacitance-based tomographic imaging, which is commonly called electrical capacitance tomography (ECT), has been developed for two decades. This paper briefly introduces ECT sensors, capacitance measuring circuits, image reconstruction algorithms, and a wide range of challenging applications, including multi-phase measurement of oil pipelines, wet gas pipelines, wet gas separators, milk production lines, pneumatic conveyors, cyclone separators and fluidized beds. A recent development is tomography-based control of oil separators and fluidized bed dryers.
