Abstract

Contamination control is important in many kinds of liquid systems. It may be (a) to insure a clean product during packaging, (b) to maintain the performance of a fluid power control system, (c) to monitor the effectiveness of a flushing process for cleaning parts, or (d) to assure cleanliness of photographic and chemical processing liquids. The applications are almost unlimited. The most effective control is achieved by continuous, on-stream monitoring of the flowing liquid. This paper discusses several types of monitors; what each one measures; correlation and calibration techniques; various applications; sampling and operational considerations; and some of the advantages and disadvantages.
