| Abstract: | This paper introduces a method of measuring the massflow of coal powder.It is based on that passing the elbow the momentum of the fluid is changed and its value is de- pended on the flowing parameter.A mathematical model,the electric block diagram and main program are illustrated,and the experimental results using talcum and coal powder as solid material are showed.The merits of this method are a large measuring range of mass mix- ture ratio of solid to gas,no requirement of the diameter of pipe which transfers the measured fluid,and small flow resistance.The experimental results exhibit this method is feasible. |
