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 CAPABILITIES <br /> • Operating temperature Range:-25°C to+50°C <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. gtwg <br /> 5c-ASor <br /> SENSOR MODELS IN�CQII.� <br /> Table is Sensor Part Numbers <br /> Form No. Description <br /> 794380-301 Single-Point Hydrostatic Sensor <br /> Dual-Point Hydrostatlo 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 /> l • 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 /> i <br /> 3 <br />
