ABSTRACT:
A system to measure the flow of coal using externally mounted vibration sensors. One or more vibration sensors are located on a pipe section which is not impacted by coal particles in the flow stream. This sensor measures the ambient pipe vibration. An equal number of vibration sensors is located on a pipe section impacted by the coal particles in the flow stream which will measure the ambient pipe vibrations plus the coal particle impact vibrations. The two vibration outputs from the sensors are combined to develop a coal or particle flow signal.
