APPARATUS FOR AND METHOD OF MONITORING PARTICULATE MATERIAL IN A FLUID

摘要

Apparatus for monitoring particulate material in a fluid comprising a passageway ( 17 ), through which fluid to be monitored is passed, at least a portion ( 24 ) of the boundary of the passageway ( 17 ) being translucent to enable radiation to pass through that portion ( 24 ). A camera ( 40 ) is arranged to receive such radiation and is constructed to generate electrical signals representative of the images it receives. Image analysis means ( 57 ) are connected to receive those electrical signals and to provide data from them relating to the particulate material contained within the fluid.
