Submersible level transmitters

Model 59P Level Transmitter

Model 59P Level Transmitter

The Model 59P General Purpose Level Transmitter has a 1.38" diameter Polypropylene High Temperature (PP-HT) housing and ceramic sensor.  Polyurethane cable is standard.  Different cable materials and o-rings are available.

Use it to measure Liquid Level and Depth for Water and Waste Water applications, Lift Stations, Reservoirs and Dams, Rivers, Holding Ponds, Wells, In-ground / Above Ground Tanks and with Inventory Tank Gauging.

Viatran also offers a complete range of accessories for use in level applications such as a surge protector, cable hangers and weights, meters and junction boxes.
