Dual-Point Hydrostatic Sensor
The Dual-Point Hydrostatic Reservoir Sensor accurately detects fluid level change in the reservoir and interstice of a double wall storage tank. The Dual-Point Hydrostatic Reservoir Sensor is ideal for high groundwater areas, and can differentiate between a high level alarm condition and a low level alarm condition. If an inner-wall leak occurs, the brine seeps into the tank triggering a low-level alarm, if an outer wall leak occurs, fluid seeps into the interstice triggering a high-level alarm.
