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.

An electromagnetic treatment system for a liquid comprising: a variable frequency electromagnetic signal generator operatively connected by a non-insulated conductor to the liquid; means for measuring the current intensity of a plurality of signals of varying frequency emitted by said electromagnetic signal generator after said signals have traveled a distance through the liquid, thereby defining the absorption/emission characteristics of the liquid; and means for thereafter treating the liquid with electromagnetic energy at a static treatment frequency determined on the basis of the previously defined absorption/emission characteristics of the liquid.
