IMMUM <br />J <br />The Veeder-Root Interstitial Sensor for use in Steel <br />Tanks detects the presence of liquid in the interstitial <br />space of a double-wall steel tank. Liquid in the annu- <br />lus could mean a dangerous leak. When liquid is de- <br />tected, the sensor sends an alarm signal to a TLS - <br />350R, TLS -350, ILS -350, TLS -300i, TLS -300C, <br />TLS -250i or ILS -250 monitor. The monitor's visual <br />and audible built-in alarm indicators immediately tell <br />you where the problem is, so you can quickly take <br />action to help prevent serious safety and environ- <br />mental problems. <br />The TLS -350R, TLS -350, ILS -350; TLS -300i, TLS - <br />3000, TLS -250i and ILS -250 systems feature internal <br />alarm relays that can also trigger on-site alarms for <br />even greater warning capability. The TLS -350R, <br />TLS -350, TLS -300i and TLS -300C alarm signals <br />from the sensor triggers a report showing the time <br />and the location of the alarm condition. This informa- <br />tion is stored in the system's alarm history and can <br />be retrieved through the monitor's integral printer or <br />remotely through its data communications interface. <br />The Veeder-Root Interstitial Sensor for Steel Tanks <br />can be used in the annulus of steel tanks with a <br />sensor riser pipe of 1.5" I.D. or greater. Only two <br />wires are required to connect the sensor to a TLS <br />or ILS system. <br />► The presence of any liquid in the tank's interstitial <br />space triggers a Fuel Alarm. <br />No- Operating Temperature Range: -20'C to +70'C <br />(Hydrocarbons); CPC to 7C'C (non-freezing Water). <br />► Storage Temperature Range: -4C'C to +75'C. <br />► Cable Length: 25 feet. <br />Dimensions: 2.5" high, 1.50" dia. <br />rd Components <br />QTY DESCRIPTION <br />1 Interstitial Steel Tank Sensor <br />2 Watertight Cord Grips <br />
