<p>The method comprises employing electrical contact resistance to sense whether or not there is incipient precipitation of adherent scale, paraffin wax, etc., on surfaces immersed in various liquids. The method is surprisingly sensitive, and otherwise effective, even when the liquids are electrically conductive. The method further comprises performing certain steps relative to the submerged surfaces, and/or relative to the liquids, in order to control precipitate formation. The selection of polarity, materials, etc., is caused to be such that sensitivity is maximized, and electrolytic dissolution of the submerged elements is minimized.</p> |
