| Abstract: | In this paper a software package by using finite element analysis techniques for the calculation of electric field distribution, in twophase flow concentration transducer is presented. Based on research work, the results from simulation and experiments: show that the multielectrode transducer with a rotating and homogeneous sensitivity field has an obvious advantage, i. e. the influences of flow regimes or component distribution on the measurement result has greatly reduced. |
