ABSTRACT:
Apparatus for counting particle contamination in a liquid and including a hydraulic cylinder for receiving the liquid and having mechanism for forcing the cylinder piston to exhaust the liquid from the cylinder and into a sensor where the particles are counted. The apparatus includes electric switches connected to the sensor and responsive to the position of the cylinder rod for setting the sensor in various positions for counting. Also, liquid lines are connected with the sensor, and valves are used for directing the liquid to the cylinder and the sensor, and a line restrictor creates the desired pressure in the fluid. The apparatus may receive the liquid from several lines, through a dispensing valve, or it may receive the liquid from a special container.
