NG # 02626-HW-KELLER-002
The Keller LevelRat is a rugged, non-clogging submersible level transmitter specifically engineered for wastewater, sewage, leachate, and slurry applications. Unlike general-purpose transmitters that utilize standard recessed ports or thin diaphragm caps susceptible to clogging from suspended solids and bio-fouling, the LevelRat features a wide, flush 316L stainless steel diaphragm protected by a removable high-viscosity nose cap.
