Abstract
A system and method for monitoring or detecting a level of biofilm growth in a fluid system and controlling operating parameters of the fluid system based a measured level of growth. The monitoring system and method comprises a dye injection system for periodically injecting dye into a portion of fluid from the fluid system, passing the portion of fluid though a narrow lumen tube to achieve laminar flow and using a light source and optical sensor to detect a transmission or emission indicating a level of biofilm growth in the tube corresponding to a level of growth on components in the fluid system. Information based upon the measurements or calculations made by the monitoring system may be used to manually or automatically alter various operating parameters to control the fluid system and aid in maintaining stable operation of the fluid system within preferred specifications.
