electrical tomography is, in certain cases, the most attractive method for real imaging of industrial processes, because of its inherent simplicity, rugged construction of the tomographer and high-speed capability. This paper presents examples illustrating applications of electrical tomography for imaging fluidized beds, bubble columns and pneumatic conveyors. electrical tomography opens up new ways for processing, imaging and modelling multi-phase flows as shown by 2D and 3D images illustrating the various types of flow morphology.
