Abstract
The invention provides a sensing system for sensing process conditions within an ultrasonic process tank that includes process liquid, the liquid being subjected to ultrasound produced by transducers coupled to a generator. The sensing system includes an enclosure for housing a sample liquid, the enclosure passing ultrasonic energy from the process liquid to the sample liquid, the sample liquid being responsive to the ultrasonic energy, and at least one sensing device within the sample liquid, the sensing device generating signals indicative of characteristics of the sample liquid. The sample liquid includes materials adapted to produce chemiluminescence in response to the ultrasonic energy. The at least one sensing device includes a photo sensor for sensing the produced chemiluminescence and generating signals in response to the produced chemiluminescence.
