Measuring Gas-solid Two-phase Mass Flow Based on Thermal Sensors Fusion

提出了热式多传感器信息融合的气固质量流量检测方法 .采用复合传感器 ,可同时按换热法和热平衡法两种原理进行固相流量在线测量 .研究了两种方法的测量原理和数学模型 .结合两种方法的测量结果 ,经过信息融合处理 。

A new measuring method for gas solid two phase mass flow based on sensor fusion is presented. By using compound sensor, gas solid two phase mass flow can be measured on line in accordance with both thermal convection principle and thermal energy balance princile. The principles are introduced and the mathematics model is built. Combining two methods and their results in an intelligent manner, it is possible to improve the accuracy and the reliability of measurement.
