FEB 12 '97 1 3 : 1 2 FROM VEEDER-ROOT SERV I CF 1 0 1 Tt;5990H PAGE . 009/010 <br />File MR10623 Page l Issued: 2-14-96 <br />D E S C R T P O N <br />Wireless line leak detector, Form Nos. 849490-001, -002. <br />: • <br />These retrofit kits consist of a wireless line leak sensor <br />that replaces the capacitor cover on the submersible pump of a <br />remote controlled dispensing device; a bracket that attaches to <br />the line leak sensor to maintain the capacitor cover; a check <br />valve assembly (Form No. 849490-002 only) that replaces the <br />submersible pump's mechanical line leak detector (LLD) or LLD <br />port.plug; a tank port fitting (Form No. 849490-001 only) that <br />installs at the line pressure test port; a sensing line that <br />connects the leak sensor to the check valve or tank port fitting; <br />and an AC interface module and WPLLD controller modules that <br />install in the power area of a Listed Veeder Root TLS -350 or <br />-350R control unit. <br />The wireless line leak sensor is contained within an <br />explosion proof housing and contains a pressure sensor that <br />monitors line pressure in the gasoline piping system; a flame <br />arrestor; and a transducer circuit board that connects to the <br />submersible pump power wires to transmit data to the control <br />unit. In the event of a leak, the control unit shuts off power <br />to the pumps. The leak sensor has been investigated for use in <br />Class I, Group D hazardous locations. The leak detection <br />capabilities of this device have not been investigated. <br />The Form No. 849490-001 is for use with F E Petro pumps and <br />the Form No_ 849490-002 is for use with Red Jacket pumps. <br />The system has been investigated for gasoline and a full <br />range of ethanol and methanol blends. <br />RATINGS: <br />Input Rating - 240 V ac, 50 VA. <br />Maximum Ambient Temperature - 4010C. <br />f <br />
