eVEEDER-ROOT CONNECTED, SECURE. COMPLIANT. DigitaL Pressurized Line Leak Detection System Why DPLLD for Detecting Line Leaks? The Veeder-Root Digital Pressurized Line Leak Detection(DPLLD)system is designed to meet your everyday compliance needs in a variety of applications. Our patented technology performs precision line leak testing at full pump pressure for 0.1 Gallons Per Hour(GPH)/0.38 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 GPH/11.4 LPH test requirements. DPLLD offers flexible testing and digital reporting options, helping to detect catastrophic leaks. When paired with a TLS-450PLUS Automatic Tank Gauge(ATG),customers can monitor up to 1,178 gallons/4,459 liters of fuel line volume. 4-- ,rd 4)_ 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. SYSTEM FEATURES Equipment Design • Pressure sensor is installed easily without breaking piping or adding anew sump • Stainless steel construction meets the challenges of a highly corrosive environment • Test lines at full pressure for quick and accurate results,without restricting fuel flow rate • Not impacted by thermal contraction of fuel in the line due to changes in temperature System Functionality • Monitors line pressure during dispensing activity to ensure a catastrophic leak is not occurring during a dispense - If a leak is detected at a pre-set pressure threshold,the system will shutoff power to the Submersible Turbine Pump (STP)to minimize environmental damage and help prevent a public safety issue Conducts test once all dispensing is completed to ensure the integrity of the line Test can be manually performed to reset alarms Built-in calibration verification to notify the site operator when the pressure transducer is not operating properly Auto-Confirm function,when enabled,runs a second line leak test,if an initial test failure occurs,to verify and reduce false alarms due to mechanical issues that may be occurring in other parts of the fueling system • Provides two alarm shutdown options when failure occurs 1.Standard Dispenser Shutdown(Alarm and Shutdown) 2.Optional No Shutdown(Alarm Only)
