Submersible level transmitters

Model 59S Level Transmitter

Model 59S Level Transmitter

Designed with a slim 0.75 inch diameter body to enable it to fit small access ports, you can use it to measure Liquid Level and Depth for Water and Waste Water applications, at Lift Stations, Shipboard, In-ground / Above Ground Tanks and with Inventory Tank Gauging.
