The Model 311-M351 from GP:50 is a submersible lift station and sludge level transmitter. Its all stainless-steel design incorporates a 3-inch diameter, clog-resistant sensing diaphragm and corrosion-resistant protective baffle plate. These features facilitate high-accuracy level measurements, even in heavy sludge conditions. This combination of durability and accuracy, along with over 25 years of proven field service, have helped make the GP:50 Model 311-M351 an industry gold standard for water and wastewater level monitoring.
