ABSTRACT:
Improved apparatus for counting particle contamination in a liquid which is adapted for either on-line or bottle sampling. It includes a hydraulic cylinder and piston arranged to be actuated to eject a measured volume of sample liquid through a particle counter and sensor device at a pressure which will drive liquid entrained air into solution or compress the same such that air bubbles will not be counted. The measured volume is effected by operating the particle counter device only during piston travel between predetermined locations in the cylinder with the cylinder liquid connected to a hydraulic system only through the counter device. Valving is provided for operator selection of on-line or bottle sampling. When no sample is being taken a portion of the liquid flowing in a main hydraulic system flows through conduit means which is a part of the sampling circuit in parallel with a portion of the main circuit, of which conduit means the cylinder forms a part.
