The Dual-Point version is ideal for high groundwater areas,and can differentiate between a high level alarm condi- tion and a low level alarm condition. If an inner-wall leak occurs,the brine seeps into the tank triggering a low level alarm, if an outer wall leak occurs, fluid seeps into the interstice triggering a high level alarm. The Single-Point version can be used in low groundwater locations. If an inner-wall leak occurs, the brine seeps into the tank triggering a fuel alarm,or if the outer wall leaks,the brine seeps out of the tank interstice triggering a fuel alarm. Sensor Detection Capabilities - Alarm Conditions • Dual-Point Version Leak in inner wall triggers a low level alarm -Leak in outer wall triggers a high level alarm in high groundwater areas or a low level alarm in low groundwater areas. -An open sensor triggers a sensor out alarm. • Single-Point Version Leak in inner or outer wall triggers a fuel alarm in low groundwater areas. An open sensor triggers a sensor out alarm. Operating Capabilities • Operating temperature range: -25 to+50°C. • Storage temperature range: -40 to+60°C. • Operates in salt brine solution of up to 30%CaCI. • Cable length: 12 feet • Sensor dimensions: Single Point- 6" high, 2.5"diameter; Dual Point- 17.3"high, 2.5"diameter. Sensor Interface Module • TLS-350 series consoles(except TLS-350J)- Interstitial/Liquid Sensor interface module (P/N 329358-001) accepts up to 8 sensors (a maximum of 64 sensors could be monitored by the console). • TLS-350J console-4 sensors max. • TLS-300i, PC-3001,TLS-300C,TLS-300J, PC-300C consoles (no Interface Module 14"min. e Cord Weatherproof manhole grip junction box i required)-8 sensors max. • TLS-450-USM (P/N 332812-001) accepts up to 16 sensors Console Software Compatibility j q seal-oft I Riser pipe • TLS-350 series/TLS-300(Version 1 or later) cap • TLS-450 (All) Dual-point 1/2"rigid Sensor Configuration hydrostatic conduit g sensor (to console) • Single-Point Sensor- Form Number 794380-301 Float • Dual-Point Sensor-Form Number 794380-303 Brine /Reservoir level Double-wall Related Sales Literature ---- ----- tank Visit our website at www.veeder.com for more information on Veeder-Root products and services. sensors`.hssenap,ops Fig.12 Typical Hydrostatic Dual-Foint Sensor Installation 15
