Abstract
A system and a method are provided for detecting and monitoring changes in frequency in a process stream. At least one probe is placed in the process stream that is capable of detecting a change in frequency due to a build-up of mass on the probe from scale, corrosion, biofilm or the like in the process stream. A processor receives the signal produced by the probe to produce an output signal indicative of the change in frequency which is proportional to mass detected by the probe. A feeder is capable of feeding a product into the process stream as a result of the detected change in frequency of the probe to combat the mass build-up from scale, corrosion, biofilm or the like in the process stream. The system and method are further capable of measuring anti-scalant, corrosion inhibitor, biocide efficacy and controlling product feed into the process stream based on the determined efficacy.
