Sub-X™ IS Transmitter
Submersible Level Transmitter
for Continuous Level Monitoring Applications

The Sub-X™ IS submersible level transmitter is specially designed for continuous level monitoring in the harshest environments including sanitary and stormwater lift stations having suspended solids. The instrument measures the hydrostatic pressure of the liquid above the sensor and outputs a 4-20mA signal proportional to the level.
The robust design of the Sub-X™ IS transmitter provides a reliable and low maintenance solution for critical level control applications where other level sensors easily foul. Some examples include: sewage, stormwater and effluent pump stations, lagoons, equalization tanks and holding ponds, raw water wet wells/intakes, storage tanks and reservoirs.
Unit is suitable for operation in Class 1, Div 1, Groups C, D, T4 Hazardous Locations with optional Intrinsic Safety Barrier.
