Leak Sensor U offers a variety of sens. <br />ing options that provide early warning <br />of liquid and vapor seepages from <br />storage tank systems. Double Wall tank, <br />monitoring well, well cap and combing: <br />tion sensors allow Leak Sensor U to <br />monitor virtually any type of storage <br />tank situations. Liquid sensing ele- <br />ments immediately detect the pres- <br />Multiple channel capability <br />pinpoints leak location <br />To accommodate multiple tank <br />installations and various system <br />configurations, Leak Sensor U models <br />are available to monitor up to 32 sen- <br />sors per alarm panel. As a result, the <br />specific sensor sending the signal is <br />identified, and the exact location of the <br />leak can be readily determined. Com- <br />pact sensing probes have flexible <br />cables for simple installation in double - <br />walled steel or FRP tanks, as well as . <br />wet or vadose (dry) zone monitoring <br />wells. Alarms feature a field adjustable <br />setpoint for background vapor <br />screening. <br />Fast, simple installation <br />Leak Sensor U can be installed quickly <br />and easily without the need for excava- <br />tion. Flexible cables permit the sensing <br />probes to be fed to precise points in <br />the annular space between the primary <br />and secondary tanks or to be easily <br />positioned in the monitoring well. The <br />optional well cap sensor acts as a sim- <br />ple replacement for existing caps. <br />Non -corrosive probes work up to <br />1,000 feet from the control panel with <br />18 gauge wire, and up to 4,000 feet <br />with 12 gauge wire. The compact <br />electronic control panel can be <br />mounted virtually anywhere within <br />the operator's area for easy visual and <br />physical access. <br />Dependable, maintenance <br />free operation <br />Once installed, Leak Sensor II requires <br />no maintenance service. All electronic <br />functions are designed to be continu- <br />ally self -checking. The entire system is <br />automatically checked to determine the <br />integrity of sensors, outputs, inputs, <br />power supply, alarms and displays, <br />ensuring that every aspect of the sys- <br />tem is operational at all times. Both vis- <br />ual and audible alarms alert to possible <br />problems or malfunctions. <br />ence of fluids in undesired areas and <br />absorption sensitive resistors recognize <br />the presence of most combustible and <br />organic gases. <br />Since vapors can travel faster than <br />liquids in unlimited directions, the vapor <br />sensing capability of Leak Sensor U can <br />warn of a potential problem much <br />quicker than conventional liquid -only <br />Liouid Probe Application <br />1-0 <br />Vnnnr 7rnhca Anplination <br />systems. When either liquid or vapor <br />escapes from the tank storage system, <br />a master visual and audible alarm is <br />triggered to warn of the leak. Leak <br />Sensor It's vapor sensing system can <br />be tuned to be so sensitive that vapors <br />can be detected before they're <br />discerned by smell. <br />'�J •� �e.. �:• a•.0.,','m •.oma.'. �•4 : pC�.e <br />�*3, to <br />x ,s <br />re l'.q.•gM��1..Y <br />P dT � ®• ; 4 a•i- <br />O w LS l ,�:7�.a.;ca_ 4� xg'.? cSa yL•i E��jry.t ,: <br />��' ® c•� �, si®®� a ,a`i�'�:'$ t '%,�-'��..4 �: ,+ 1r „�-...-,':� 1' if a..,,F'" <br />
