ABSTRACT:
Method and apparatus for indicating mass flow of a solid particulate material through a rotary feeder. A radiation source and detector are positioned in a manner whereby radiation flux is directed through, and attenuated by, particulate material contained in rotating pockets. A Cesium-137 gamma source can be mounted within the shaft of the feeder, and one or more detectors can be mounted outside of the feeder housing. The detected signal is indicative of the mass of particulate material contained within a given pocket rotating within the feeder.
