f <br /> CONNECTED, SECURE, COMPLIANT. <br /> 0 <br /> Why DPLLD for Detecting Line Leaks? <br /> The Vedder-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 /> M1. <br /> x _ <br /> 0 <br /> r <br /> P' � k a • „, <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 />
