<4� ) VEEDER-ROOT <br />CONNECTED, SECURE, COMPLIANT, <br />Why DPLLD for Detecting Line Leaks? <br />The Veeder-Root Digital Pressurized Line Leak Detection (DPLLD) system is designed to meet your everyday compliance needs in a variety <br />of applications. Our patented technology performs precision line leak testing at full pump pressure for 0.1 Gallons Per Hour (GPH)/0.38 <br />Liters Per Hour (LPH) and 0.2 GPH/0.76 LPH, and a pressure decay test to meet the U.S. Environmental Protection Agency (EPA) 3.0 <br />GPH/11.4 LPH test requirements. DPLLD offers flexible testing and digital reporting options, helping to detect catastrophic leaks. When <br />paired with a TLS-450PLUS Automatic Tank Gauge (ATG), customers can monitor up to 1,178 gallons/4,459 liters of fuel line volume. <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 />Equipment Design <br />Pressure sensor is installed easily without breaking piping or adding a new sump <br />Stainless steel construction meets the challenges of a highly corrosive environment <br />Test lines at full pressure for quick and accurate results, without restricting fuel flow rate <br />Not impacted by thermal contraction of fuel in the line due to changes in temperature <br />System Functionality <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 help prevent a public safety issue <br />Conducts test once all dispensing is completed to ensure the integrity of the line <br />• Test can be manually performed to reset alarms <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 <br />1. Standard Dispenser Shutdown (Alarm and Shutdown) <br />2. Optional No Shutdown (Alarm Only) <br />veeder.com <br />
