Veeder-Root's Hydrostatic Reservoir Sensor accu- rately detects fluid level change in the reservoir and interstice of a double-wall storage tank. Available in a dual -float or single -float configuration. The Dual -Float Hydrostatic Sensor is ideal for high groundwater areas, and can differentiate between a high level alarm condition and a low level alar condition. If an inner -wall leak occurs, the brine solution seeps into the tank lowering the brine level in the reservoir. The Dual -Float Sensor will then trigger a low level alarm. If an outer -wall leak occurs, the groundwater seeps into the reservoir. The Dual -Float Sensor will then trigger a high level alar. T 7Erlo The Single -Float Sensor is ideal for low groundwater areas, since it only detects low level alarm conditions. If an inner -wall leak occurs, the brine solution seeps into the tank. If an outer -wall leak occurs, the brine solution leaks out of the tank. In both cases, the brine level decreases and the Single -Float Sensor triggers a low level alar. The housing is constructed of clear PVC, allowing the operator to pull the sensor from the reservoir to visually inspect float operation. A watertight, lockable cap prevents accidental spills on the ground surface from entering the reservoir. Veeder-Root warrants the Hydrostatic Reservoir Sensors are warranted to be free from material defects for a period of one year from the date of installation or 15 months from the date of invoice. Detection Capabilities ► Dual -Float sensor alarm conditions: • Leak in inner wall triggers a low level alarm. • Leak in outer wall triggers a high level alarm in high groundwater areas, low level alarm in low groundwater areas. ► Single -float sensor alarm conditions: • Leak in inner or outer wall triggers a low level alarm in low groundwater areas. Operating Capabilities ► Operating Temperature Range: -25•C to +401C. ► Storage Temperature Range: -40°C to + 70•C. ► Rests in salt brine solution of up to 30% calcium chloride. ► Cable length: 12 feet. ► Single -Float Sensor Dimensions: 6.0' high, 25' diameter. ► Dual -Float Sensor Dimensions. 19.3' high, 25' diameter. ► Withstands removal from reservoir several times a year without sensor damage. ► Clear plastic housing for visual inspection of float operation.
