| Abstract: | A measurement method of flow velocity in a gas-solid two-phase flow, is presented Through analyzing flow noises delivering process between two sensors, the mathematics model is built throagh two sensors signals. An improving way to measure solid velocity of gas-solid two-phase flow is given on the basis of mathematics model. The experiment result demonstrated that the method had a better measurement precision and shorter program time. An effective uay are presented for solid velocity measarement on line. |
