| Abstract: | A measuring method of two phase flow rate based on the principle of differential auto-correlation is presented. Analysis in theory shows that one channel signal is simply produced by using this method, and that the system symmetry demands is reduced. A measuring system of gas- solid two phase flow rate is established by using capacitance transducer. The results of experimental analysis verified the anti-interference capability and sensitivity are enhanced. The research results also show that the system having higher precision and better repetition. |
