5 - <br /> Veeder-Root Sensor Application 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 tow 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 Capabilities <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 /> Sensor Interface Module <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-300i, PC-300i,TLS-300C,TLS-300J, <br /> PC-300C consoles (no Interface Module 14"min.dia.
