3.The reduction Wiston surface,area makes for a Ah more responsive leak <br /> detector, significantly reducing the fuel needed to,pass through the metering f <br /> pin and poppet to allow full flow of the. pump. <br /> 4.This new fuel flow path also allows the 98LD-2000 to report fuel volume <br /> changes in the line to be calculated by the PLC=51000 interface. <br /> These arra more responsive leak detectors! Not only, are these leak detectors <br /> faster at opening up in line systems,but,when the pump is turned off, it will reset <br /> to leak sense position faster because:of the smaller,amount of fuel under the piston. <br /> Another,related benefit of the piston size is that the leak detector does not have to <br /> completely reset to cycle through the leak sense position. If the`line pressure,falls <br /> as low as 2.51 psi (when the pump is off), the leak detector is forced into the leak <br /> sense mode. For today's busy stations, this represents true hourly protection! <br /> Superior Flex Piping Per�ormance!The reduced surface area of the piston <br /> also significantly reduces the surface'area of the piston exposed to hydraulic <br /> line shock, enhancing leak detection performance not only in steel and fiber <br /> glasslines, but more importantly, enabling this leak detector to have superior <br /> CO <br /> performance in today's flexible piping systems. <br /> Higher ledk'sense pressure! Due to the reduced piston area, this leak detector <br /> stays in the fast fill position (position one)to a higher pressure, compressing vapor <br /> pockets or rernoIving stretch from flexible pipe faster.This means less time to full <br /> flow! <br /> All Vaporless leak detectors are designed to shut down if line pressure falls <br /> below 5 psi.They are the only leak detectors produced that will catch a <br /> catastrophic leak at this pressure's** while the pump is running. <br /> Patent Pending <br /> Guaranteed for 24 months after installat onto find a 3 GPH @ 10 psi leak. .' <br /> "Catastrophic"in this case is defined as•a break or rupture of the,lne that <br /> allows line pressure to fall to 5 psi or less,with the pump running. <br />
