Veeder-Root Sensor Application Guide <br /> Single-Point Mini Hydrostatic Sensor for Double Wall Sumps <br /> The Single-Point Mini Hydrostatic sensor accurately detects fluid level change in the interstice reservoir of a dou- <br /> ble-wall sump. If a leak occurs in the sump interstice, the brine seeps out of the reservoir triggering a low level <br /> alarm. <br /> Sensor Detection Capabilities - Alarm Conditions <br /> • A leak in the inner or outer sump wall triggers a Fuel alarm. <br /> • An open sensor triggers a Sensor Out alarm. <br /> Operating Capabilities <br /> • Operating temperature Range: -250C to+50°C. Rests in salt brine solution of up to 30%calcium chloride or <br /> propylene glycol. <br /> • Storage Temperature Range: -40°C to+60°C. <br /> • Dimensions: 2.5"high, 1.50"diameter <br /> • Cable length: 8 feet <br /> Sensor Interface Module <br /> • TLS-350 series consoles(except TLS-350J)- Interstitial/Liquid Sensor Interface Module(PM 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, PC-300C consoles (no Interface Module required) -8 sensors max. <br /> • TLS-450- USM (P/N 332812-001)accepts up to 16 sensors <br /> Console Software Compatibility <br /> • TLS-350 series/TLS-300(Version 1 or later) <br /> • TLS-450(All) <br /> Sensor and Installation Kit <br /> • Single-Point Mini Hydrostatic Sensor and install kit for double-wall sumps- P/N 794380-304 <br /> Related Sales Literature ________. <br /> Visit our website at Sensor in interstitial fluid reservoir <br /> www.veeder.com for more <br /> information on Veeder-Root <br /> products and services. <br /> .Concrete <br /> pad <br /> Double-wall --...._..._.___ <br /> sump <br /> Coupling and <br /> seals as required <br /> for conduit egress <br /> (customer supplied) <br /> L <br /> } Seal-off and junction box <br /> Z I (customer supplied) <br /> 1/2"conduit to <br /> TLS console Use tie wraps to keep <br /> cable clear of sump <br /> components and lid <br /> Tank <br /> I <br /> Fig. 13 Typical <br /> i <br /> Single-Point Mini-Hydroslitic Sensor Installation <br /> 16 <br />
