LD2000 Page 3 of 5 <br /> "One Way" Poppet Flow Path <br /> 4-The "One Way" Poppet Flow Path isolates pump turbulence <br /> from line leak detection at pump startup. The hardened <br /> stainless steel poppet does not dimensionally change because <br /> of thermal conditions encountered during station operation <br /> (precision metering change is insignificant down to -20° F). <br /> Reserve Ratio Piston /Poppet Combination <br /> Reverse Ratio means the leak detector has a smaller diameter <br /> piston area (smaller than the poppet it is attached to). This <br /> smaller piston area keeps the leak detector in the fast fill <br /> position (2 GPM) to a higher pressure while compressing <br /> vapor pockets and stretching flexible lines faster. This means <br /> less time to full flow! The leak detector does not have to <br /> completely reset (as with competitive leak detectors) for the <br /> poppet to be forced into the reset mode at pump startup. <br /> "Smaller Volume /Faster Response" Piston Size <br /> With a reduced piston size, there is one fourth the volume to <br /> replace when in leak search and one fourth the volume to <br /> return to the line when the pump turns off. This combination <br /> makes for a more responsive and faster leak detector. Less <br /> volume to leave the line for the leak detector to reset and <br /> catch leaks. Less volume to fill and provide full flow for <br /> dispensing! <br /> Superior Flex-Pipe Performance <br /> The reduced surface area of the piston significantly reduces <br /> the surface area exposed to hydraulic line shock. This results <br /> in enhanced performance with steel and fiberglass pipe, and <br /> especially with today's flexible pipe. <br /> Shortest Leak Detector Profile <br /> AD-The 99 series leak detectors are the lowest profile leak <br /> detectors available. <br /> ****************************** <br /> Technical Specifications 99 LD-2000 <br /> All Fuels <br /> 4Gasoline, 100% methanol, 100% ethanol, up to 15% MTBE <br /> http://www.vaporless.com/products%20ld2000.htm 6/15/03 <br />
