A new monitoring and control process has been developed which measures active treatment components in current cooling water treatment programs. This system incorporates a sensing device with a controller to monitor and control product federate. This sensor is superior to currently available technologies that either utilize automated wet chemical methods or measure product levels indirectly. Laboratory and field case studies will be discussed.
