VEEDER- ROOT CONNECTED , SECURE . COMPLIANT. <br /> DilgiltaL Pressurized UneLeak Detection <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 /> - <br /> t/ <br /> e <br /> TLSmXB <br /> TF! <br /> IL <br /> DETE ED <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 />
