-The Emco Wheaton Leak Sensor][[ System <br />Leak Sensor II 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 combina- <br />tion sensors allow Leak Sensor II to <br />monitor virtually any type of storage <br />tank situations. Liquid sensing ele- <br />ments immediately detect the pres- <br />_... <br />pinpoints- <br />To accommodate multiple tank <br />installations and various system <br />configurations, Leak Sensor II 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 II 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 II can <br />warn of a potential problem much <br />quicker than conventional liquid -only <br />Liquid Probe Application <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 U'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 />Vapor Probe Application <br />.. •• o.o..'. •. .o•.. •4 : pd.: <br />A' <br />r\ <br />yX..tr <br />'.'•.� y_� ® <br />+: 89 <br />®'®so t of ,.r'r'�4� <br />-'®'®X <br />`i .i�dT F' �� • ®.`� . }���R"�,R <br />`e.`F<! ;..Ia r.%. -.�r. .6�.:t��Q' 'i•- <br />
