Veeder-Root Sensor Application Guide �I <br /> Hydrostatic Reservoir Sensor <br /> The Hydrostatic Reservoir Sensor accurately detects fluid level change in the reservoir and interstice of a double- <br /> wall storage tank. This sensor is available in a dual- point or single- point configuration . The Dual - Point version is <br /> ideal for high groundwater areas , and can differentiate between a high level alarm condition and a low level alarm <br /> condition . If an inner-wall leak occurs, the brine seeps into the tank triggering a low level alarm , if an outer wall leak <br /> occurs , fluid seeps into the interstice triggering a high level alarm . The Single- Point version can be used in low <br /> groundwater locations . If an inner-wall leak occurs , the brine seeps into the tank triggering a fuel alarm , or if the <br /> outer wall leaks, the brine seeps out of the tank interstice triggering a fuel alarm . <br /> Table 15.
