ABSTRACT:
A method and system for utilizing variable frequency electromagnetic energy to inhibit, prevent, reverse, or alter the formation of rust or scale on various liquid contacting surfaces is disclosed. Initially, electromagnetic test signals of varied frequency are directed into a fluid filled system at a first location. The current intensity of the signals are simultaneously measured at a second location some distance from the first location. The measured current intensity, relative to the varied frequency of the test signals, provide an energy absorption/emission profile of the liquid. A treatment frequency--generally the frequency at which maximum absorption is observed--is then selected from such absorption/emission profile and treatment is carried out at such selected frequency.
