| Abstract: | Some kinds of capacitance transducers were studied to measure phase concentration of gas/solid two phase flow. The transducers were optimized respectively by using 3D finite element method(FEM) to calculate the sensitivity distribution of the sensing field. The results show that the capacitance transducer with helical shaped surface plates has an obvious advantage, i.e. the homogeneity error is less than 6%. It has been used to the industrial work site. |
