THE MEASUREMENT OF SOLIDS MASS FLOWRATE IN PNEUMATIC CONVEYING BASED ON THERMAL SENSOR FUSION

摘要

A new measuring method of gas-solid two-phase mass flow based on thermal sensor fusion is presented in this paper,. With compound sensor, gas-solid two-phase mass flow can be measured on-line by both thermal convection principle and thermal energy balance principle. The two methods combined in an intelligent processing unit, the improvement of the accuracy and the reliability of the measurement can be obtained. The principles are introduced and the mathematical model is built. Experiments are carried out in a specially designed laboratory scale pneumatic conveyor. The experimental system and measuring device are introduced. The result shows that this method can perform compound measurement.
