Veeder-Root Sensor Application Guide <br /> Interstitial Sensors for Steel Tanks <br /> The Interstitial Sensor for steel tanks detects the presence of liquid between the double walls of the tank. <br /> Sensor Detection Capabilities - Alarm Conditions <br /> • The presence of any liquid at a nominal height of 1 inch in the tank's interstitial space triggers a Fuel Alarm. <br /> • An open sensor triggers a Sensor Out alarm. <br /> Operating Capabilities <br /> • Operating temperature range: 0 to+70°C (for water), -20 to 70°C(for hydrocarbons). <br /> • Storage temperature range: -40 to+70°C. <br /> • Sensor dimensions: 2.5" high, 1.5"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-3 sensors max. <br /> • TLS-300i, PC-300i,TLS-300C,TLS-300J, PC-300C Consoles(no interface module required)-8 sensors max. <br /> • ILS-350 Console-A Two-Wire module (P/N 329675-001) accepts up to 4 sensors (a maximum of 16 sensors <br /> could be monitored by the console). <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 /> • ILS-350(All) <br /> • TLS-450 (All) <br /> Compatible Fuels <br /> • Unleaded gasoline <br /> • Unleaded with up to 5%methanol, <br /> 15%ethanol,or 15%MTBE 14"min.dia. <br /> • Leaded gasoline manhole Cord grip <br /> • Diesel <br /> • Kerosene <br /> • Jet fuel <br /> 1/2"to 2' <br /> • Aviation gasoline Reducer a—Seal-off <br /> u <br /> Sensor/Cable Length Configurations Leader cable `° �(t/o Cos ole)suit <br /> • <br /> Interstitial Sensor with 16-foot cable- weatherproof junction <br /> box with 1/2-inch N.P.T. <br /> Form Number 794390-420 2"dia.riser threads(16 Cubic inch <br /> volume minimum) <br /> • Interstitial Sensor with 30-foot cable- <br /> Form Number 794390-460 <br /> Accessories Sensor <br /> Riser cap and adaptor kit(2")- P/N 312020-928 Steel tank <br /> Related Sales Literature <br /> Sensor Switch must <br /> Visit our website at www.veeder.com for more rest on bottom of tank <br /> information on Veeder-Root products and services. <br /> Fig.8 Typical Interstitial Sensor Installation-Steel LIST <br /> 12 <br />
