VEEDEWROOT Bectronic Pressurized - Leak Detection ( PLLD) Why Electronic PLLD for Detecting Line Leaks ? The Veeder-Root Electronic Pressurized Line Leak Detection (PLLD) system is designed to meet your everyday compliance needs . Our patented technology performs precision line leak testing at full pump pressure for 0 . 1 and 0. 2 gallons per hour (gph) and a pressure 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 applications, and 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 1178 gallons of fuel line volume. f - CIVEEDER- LL 42 10 TLSmXB IL LEAK DETECTED IL j If the pressure is out of normal range, the TLS450PLUS will record a failing result and generate an audible and visual alarm for the store operator. SYSTEM FEATURES • Pressure sensor is installed without breaking piping or adding a new sump, and is constructed with stainless steel to meet the challenges of a highly corrosive environment. • Test lines at full pressure for quick and accurate results, without restricting fuel flow rate. • Conducts a 3. 0 gph test, which meets EPA and NFPA 30 release detection requirement for pressurized line systems, once all dispensing is completed to ensure the integrity of the line. • Standard 3. 0 gph and optional 0. 1 and 0. 2 gph tests can be manually performed to reset alarms . • 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 prevent a public safety issue. • 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: Standard Dispenser Shutdown (Alarm and Shutdown) and Optional No Shutdown (Alarm Only) . Not impacted by thermal contraction of fuel in the line due to changes in temperature. www, veeder. com
