s <br />Hydrostatic Sensor Installation Guide System Description_ <br />seeps out of the tank. in both cases, the brine level decreases and the Single -Point Sensor triggers a low level <br />alarm. <br />The housing is constructed of clear PVC, allowing the operator to pull the sensor from the reservoir to visually <br />inspect float operation. A vented riser cap restricts liquid from entering the reservoir. <br />DETECTION CAPABILITIES <br />• Dual -Point sensor alarm conditions: <br />Leak in inner wall triggers a low level alarm. <br />- Leak in outer wall triggers a high level alarm in high groundwater areas and a Low level alarm in low groundwater <br />areas. <br />• Single -Point sensor alarm conditions: <br />- Leak in inner or outer wall triggers a low level alarm in low groundwater areas. <br />• Operating temperature Range: -25 °C to +500C <br />• Storage Temperature Range: -40°C to +70"C <br />• Operates in salt brine solutions containing up to 30% calcium chloride. <br />• Cable length: 12 feet <br />• Single -Point Sensor Dimensions: 6.0" high, 2.5" diameter <br />• Dual -Point Sensor Dimensions: 16.3" high (-302) or 17.3" high (-303), 2.5" diameter <br />• Clear PVC housing permits visual inspection of float operation. <br />Table 1: Sensor Part Numbers <br />Form No. I Description <br />794380-301 w -1 Single -Point Hydrostatic Sensor <br />Dual -Point Hydrostatic Sensors <br />INSTALLATION KITS <br />The older metal riser cap and vent tube are being phased out and replaced with a plastic riser cap kit. Part <br />numbers for both types are listed below. <br />Old style Metal Riser Cap and Vent Tube <br />• Metal Riser Cap (P/N 329992-001) <br />• Vent tube (P/N 329981-001) <br />New Style Plastic Cap Kit (P/N 330020-435) - see Table 2 and Figure 1 below for kit contents. <br />3 <br />
