Description

ABSTRACT A system for quickly indicating changes in density of a flow of material using a radiactive source and detector where the count rate indicative of density is processed for sensing signi- ficant changes in the density in the flow of material as distinguished from random changes and for producing an indication of such changes. In one aspect of the invention, a time filter is utilized with an RC circuit and diodes to require a count rate indicative of a significant density change before producing an indication. In another aspect of the present invention the count rate is processed with respect to a predetermined formulation to determine the occurrence of a significant density change in a time frame and for producing an indication when such change occurs.
