VEEDER- ROOT <br /> Une Leak Detection ( PLLD) <br /> Why Electronic PLLD for Detecting Line Leaks ? <br /> The Veeder-Root Electronic Pressurized Line Leak Detection (PLLD) system is designed to meet your everyday compliance needs . Our <br /> patented technology performs precision line leak testing at full pump pressure for 0 . 1 and 0 . 2 gallons per hour (gph) and a pressure <br /> decay test to meet the U .S. EPA 3 . 0 gph test requirements. The Veeder-Root Electronic PLLD system works in a variety of pressurized line <br /> applications, and offers flexible testing and digital reporting options, helping to detect catastrophic leaks . When paired with a TLS-450PLUS <br /> Automatic Tank Gauge (ATG), customers can monitor up to 1178 gallons of fuel line volume. <br /> e44 VEEM-110ar <br /> Ill <br /> ® - <br /> t..�LEAK DETECrED IF IL <br /> I!:&_ - I <br /> If the pressure is out of normal range, the TLS-450PLUS will record a failing result and generate an audible and visual alarm for the store operator. <br /> SYSTEM FEATURES <br /> • Pressure sensor is installed without breaking piping or adding a new sump, and is constructed with stainless steel <br /> to meet the challenges of a highly corrosive environment. <br /> • Test lines at full pressure for quick and accurate results, without restricting fuel flow rate . <br /> Conducts a 3 . 0 gph test, which meets EPA and NFPA 30 release detection requirement for pressurized line systems, <br /> once all dispensing is completed to ensure the integrity of the line. <br /> Standard 3 . 0 gph and optional 0 . 1 and 0. 2 gph tests can be manually performed to reset alarms . <br /> Monitors line pressure during dispensing activity to ensure a catastrophic leak is not occurring during a dispense . <br /> If a leak is detected at a pre-set pressure threshold , the system will shutoff power to the Submersible Turbine Pump <br /> (STP) to minimize environmental damage and prevent a public safety issue. <br /> • Built- in calibration verification to notify the site operator when the pressure transducer is not operating properly. <br /> • Auto-Confirm function , when enabled, runs a second line leak test, if an initial test failure occurs, to verify and reduce <br /> false alarms due to mechanical issues that may be occurring in other parts of the fueling system . <br /> Provides two alarm shutdown options when failure occurs: Standard Dispenser Shutdown (Alarm and Shutdown) <br /> and Optional No Shutdown (Alarm Only) . <br /> Not impacted by thermal contraction of fuel in the line due to changes in temperature. <br /> www. veeder. com <br />
