0-40″ thru 835′ WC, High Accuracy, PUR Cable Standard, Stainless Steel Sensor and Housing
The Model 591 Detachable Level Transmitter is similar to the 590, but provides a higher accuracy solution. Detachable design allows for a quick sensor swap without the removal of the installed polyurethane standard cable. PVC and FEP cables are also available. 590/591 have the deepest level rating at 835′. Sensor head and/or cable can be ordered separately. A complete range of accessories for use in level applications are available, many from stock.

IP-68 Rated
Low Pressure Applications
The Model 591 High Accuracy Detachable Level Transmitter allows for a quick sensor swap without the removal of the installed cable.
No special tools are required. Simply pull up the sensor, twist the sensor coupling sleeve till it is no longer engaged and then simply separate the two halves.
591 is constructed of stainless steel housing and sensor module, with a polyurethane cable as standard. Different cable materials and o rings are available.
Use it to measure Liquid Level and Depth for Water and Waste Water applications, at 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.
Replacement sensor heads and/or cables can be purchased separately
