GP:50 Model 311-M351 Submersible Lift Station Sludge Level Transmitter

GP:50 Model 311- M351 Submersible Lift Station Sludge level transmitter is one of the most rugged and popular level transmitter in the waste water treatment market.

Product Overview:

Its all stainless-steel design incorporatesa3-inch diameter clog-resistant sensing diaphragm and corrosion-resistant protective baffle plate. These features facilitate high-accuracy level measurements, even in heavy sludge conditions, helped make the GP:50 Model 311-M351 an industry gold standard for water and wastewater level monitoring.
