' Veeder-Root Sensor Application Guide 111 tM #212 Single-Point Mini Hydrostatic Sensor for Double Wall Sumps ' The Single-Point Mini Hydrostatic sensor accurately detects fluid level change in the interstice reservoir of a dou- ble-wall sump. If a leak occurs in the sump interstice, the brine seeps out of the reservoir triggering a low level ' alarm. Sensor Detection Capabilities - Alarm Conditions • A leak in the inner or outer sump wall triggers a Fuel alarm. • An open sensor triggers a Sensor Out alarm. Operating Capabilities ' Operating temperature Range: -250C to+50°C. Rests in salt brine solution of up to 30% calcium chloride or propylene glycol. • Storage Temperature Range: -40° C to+60" C. ' Dimensions: 2.5" high, 1.50"diameter • Cable length: 8 feet ' 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 required) -8 sensors max. • TLS-450- USM (P/N 332812-001) accepts up to 16 sensors ' Console Software Compatibility • TLS-350 series/TLS-300 (Version 1 or later) ' TLS-450 (All) Sensor and Installation Kit ' Single-Point Mini Hydrostatic Sensor and install kit for double-wall sumps- P/N 794380-304 Related Sales Literature Visit our website at Sensor in interstitial fluid reservoir ' www.veedercom for more information on Veeder-Root products and services.
