Evaluation of electrical resistance tomography with voltage excitation compared with electrical capacitance tomography

Measurement Science and Technology, 2018
Normally, a gas–solids flow should be non-conductive. With the increase in moisture content in a gas–solids flow, the non-conductive flow may become low-conductive. For the measurement of low-conductive materials, i.e. particles with high moisture content, in the pharmaceutical industry, both electrical capacitance tomography (ECT) and traditional ...
