WL420 Submersible Hydrostatic Level Transmitter

The WL420 is a rugged submersible hydrostatic level transmitter engineered for continuous liquid depth monitoring in deep water wells, underground storage tanks, chemical reservoirs, and water treatment vessels. It uses an ultra-stable 316L stainless steel piezoresistive diaphragm and a vented polyurethane (PUR) cable that balances atmospheric pressure changes automatically.
