<p>Apparatus for indicating mass flow of a solid particulate material through a star wheel feeder (14,16) having a radiation source (32) and detectors (34A, 34B) so positioned that radiation flux (36) is directed through, and attenuated by, particulate material (24) contained in the pockets (18) of the star wheel. The detected signal is indicative of the mass of particulate material (24) contained within the pockets (18) and is used with a feeder speed signal to determine mass-flow through the feeder (14,16).</p> |
