Received by EHD on 3/ 15/2022 VEEDER- ROOT PressurizedELectronic - ction ( 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. E _ jJ9 . . 100 TLSmXB unnWWW i DETEIVED 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 • 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. coni
