ABSTRACT:
A method and apparatus for determining the level of particulate contamination in a plurality of liquid sources. The apparatus comprises first and second control valves each having a number of valve elements equal in number to the number of liquid sources, with analytical equipment to determine the amount of particulate contamination in a fluid sample, disposed therebetween. Samples are withdrawn from and returned to the same liquid source. A common valve controller insures that the control valves are maintained at a common valve setting. The analytical equipment is capable of detecting particulate contaminants as small as 0.3 micron.
