Substitution of components may Impair Intrinsic safety. <br />System Description <br />The Veeder-Root Hydrostatic Reservoir Sensor accurately detects the fluid level change in the reservoir and <br />interstitial space of a double-wall fiberglass tank. <br />The hydrostatic sensor is available in a Dual -Point or Single -Point configuration. The Dual -Point version is ideal <br />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 solution seeps into the tank lowering the brine level in the <br />reservoir. The Dual -Point Sensor will then trigger a low level alarm. If an outer -wall leak occurs, the groundwater <br />seeps into the reservoir. The Dual -Point sensor will then trigger a high level alarm. <br />The Single -Point Sensor is ideal for low groundwater areas, since it only detects low level alarm conditions. If an <br />inner -wall leak occurs, the brine solution seeps into the tank. If an outer -wall leak occurs, the brine solution <br />
