摘要
A new method for measuring the solid flow rate in gas solid two phase flow is introduced in this paper. An electrically heated probe was put in a gas solid two phase flow. For certain solid particles, the flow media with different velocities and concentrations of particles produced different effects on heat transfer with the probe. The solid flow rate can be measured according to the intensity of heat transfer. Experiments were made on a pilot pneumatic conveying device. Research results prove that the method works effectively and reliably.
