Veeder-Root Sensor Applottion Guide <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. <br />The Dual -Point version is ideal for high groundwater areas, and can differentiate between a high level alarm condi- <br />tion and a low level alarm condition. If an inner -wall leak occurs, the brine seeps into the tank triggering a low level <br />alarm, if an outer wall leak occurs, fluid seeps into the interstice triggering a high level alarm. <br />The Single -Point version can be used in low groundwater locations. If an inner -wall leak occurs, the brine seeps <br />into the tank triggering a fuel alarm, or if the outer wall leaks, the brine seeps out of the tank interstice triggering a <br />fuel alarm. <br />Sensor Detection Capabilities - Alarm Conditions <br />• Dual -Point Version <br />- Leak in inner wall triggers a low level alarm <br />- Leak in outer wall triggers a high level alarm in high groundwater areas or a low level alarm in low <br />groundwater areas. <br />- An open sensor triggers a sensor out alarm. <br />• Single -Point Version <br />- Leak in inner or outer wall triggers a fuel alarm in low groundwater areas. <br />- An open sensor triggers a sensor out alarm. <br />• Operating temperature range: -25 to +50°C. <br />• Storage temperature range: -40 to +60°C. <br />• Operates in salt brine solution of up to 30% CaCI. <br />• Cable length: 12 feet <br />• Sensor dimensions: Single Point - 6" high, 2.5" diameter; Dual Point - 17.3" high, 2.5" diameter. <br />• TLS -350 series consoles (except TLS -350J) - Interstitial/Liquid Sensor interface module (P/N 329358-001) <br />accepts up to 8 sensors (a maximum of 64 sensors could be monitored by the console). <br />• TLS -350J console - 4 sensors max. <br />• TLS -3001, PC -3001, TLS -300C, TLS -300J, <br />PC -300C consoles no Interface Module 14" min. dia.
