<p>A system (1) and a method for monitoring fouling in a fluid stream (10) are provided. A light source (22) generates a light path directed to two distinct portions (24, 26) of a fluid stream (10), one of which includes a translucent conduit (14). The conduit (14) experiences fouling on the walls thereof. The light directed towards the conduit (14) is absorbed or scattered to a varying degree as a function of foulant thickness and composition and the wavelength of the light employed. A comparison of foulant contained in the fluid (12) itself may be compared to the foulant in the conduit, and a signal representative thereof can be generated. As a result, dosage of agents (46) added to the fluid stream to control the foulant in the system may be controlled.</p> |
