ABSTRACT:
A laser light beam is projected through a fluid measuring cell having a fluid accommodating chamber and inlet and outlet pathways for the fluid. The light is separated into transmitted light and scattered light. Separate light detectors sense the transmitted light and scattered light. An electric control circuit uses the variations of the intensity of the transmitted light to compensate for fluctuations in the intensity of the scattered light to provide an output related to the intensity of the scattered light.
