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

The GP:50 311-M351 Submersible Lift Station Sludge Level Transmitter is an industry-standard hydrostatic pressure sensor custom-engineered for the harsh environmental challenges of water treatment facilities, wet wells, and sewage infrastructure. Built with an all-welded, leak-proof stainless steel housing, the 311-M351 features a unique 3-inch large-diameter sensing diaphragm coupled with a heavy-duty, corrosion-resistant protective baffle plate.

This specialised open architecture is purposefully built to operate continuously in viscous fluids without clogging, facilitating exceptional accuracy even under dense grease and heavy sludge loading conditions. The fully encapsulated internal electronics contain highly robust RFI, EMI, and lightning surge protection arrays to protect data transmission channels against volatile electrical spikes. Operating reliably across a broad pressure  range from 0-5 to 0-500 PSI, this transmitter outputs standard 4-20mA, 0-5Vdc, or 3mV/V process signals to fit existing control platforms and ensure long-term, trouble-free deployment.

  • All welded stainless steel construction
  • Clog-resistant 3-inch diaphragm utilises a large-diameter sensor face and a rugged protective baffle plate to prevent sludge fouling.
  • Rugged, all enclosed electronics
  • 0-5Vdc, 3mV/V or 4-20mA outputs
  • RFI and surge protection
  • Leak proof

To meet the exacting requirements of your application, the model 311-M351 is offered with many options for output, pressure range and connector types, so specifications can vary. Please download the product data sheet for full details
