Abstract
The granulometer uses a measuring laser beam (9) to illuminate particulate and, through the measure of the distribution of the light diffused by the examined particulate and gathered by a collecting lens (11), measures the concentration of particulate in the fluid in low concentration standards, the laser beam (9) being a converging one focused on a laser opaque shell (12) that partly covers the same lens.
Claims4
An optical granulometer for measuring the concentration of particulate present in a fluid at low concentration standards, that uses a measuring laser beam to illuminate the particulate, by means of the measurement of the distribution of the light diffused by the particulate and gathered by a collecting lens with a focal length characterized in that the measuring laser beam is a converging laser beam focused on a laser opaque shell that partly covers said collecting lens.
