Abstract
A self-cleaning sensor to determine a level of a liquid includes a tube with an interior coating and a plurality of horizontally aligned, electrically isolated, electrical contacts. The self-cleaning sensor includes the plurality of horizontally aligned, electrically isolated, electrical contacts that each terminate in an outer surface of an interior wall of the tube and are electrically connected to one or more electrical devices in a cap residing on the tube. Additionally, the self-cleaning sensor includes a float that is composed of a low density, low dielectric constant material buoyant in one or more liquids to be measured where each horizontal dimension of the float corresponds to each horizontal dimension of the tube.
