Series RF Level Controls employ radio frequency technology to precisely monitor the level of almost any liquid or solid. Probes are unaffected by product build-up, even with problem materials like latex paint, which can quickly disable most mechanical controls. Each unit is quickly and easily calibrated in the field for the unique dielectric constant characteristics of the specific product being controlled. No moving parts means years of dependable service. A complete system requires a sensing probe and separate control box.
