This means less time to full flow. The leak <br /> detector does not have to completely reset (as with competitive leak detectors) for the poppet to be forced <br /> into the reset mode at pump start-up. <br /> Smaller Volume / Faster Response Piston Size <br /> With a reduced piston size, there is one-fourth the fuel volurne to replace when in leak search and one-fourth <br /> the fuel volurne to return to the line when the pump turns off.This combination makes for a more responsive <br /> and faster leak detector. Less volume to leave the line for the leak detector to reset and catch leaks. Les-S <br /> volume to fill and provide: full flow for dispensing' <br /> Superior Flex-Pipe Performance <br /> 'rhe reduced surface area of the piston significantly reduces the surface area exposed to hydraulic line <br /> shock. This results in enhanced performance with steel and fiberglass pipe, and especially with today's <br /> flexible pipe. <br /> 99 LD-2000\E <br /> In the early 1990'x.the first commercially successful flexible pipe,Total Containment PP-1500.was introduced <br /> to the U. S. petroleum industry. Due to the flexibility of this pipe system, no line leak detection would work. <br /> In 1992, the LD-2000\E was certified for 3 GPH G 10 PSI on Total Containment PP-1500 pipe. The <br /> 99 LD-2000\E is still required for existing PP-1500 pipe. Additionally, today the 99 LD-2000\E is used in <br /> sites that have the same line characteristics as the LD-20WE was originally certified for, even though the <br /> pipe is different. The original ceitiflcation of the LD-20001E concerned the bleed-back modulus of PP-1500 <br /> pipe. Today, lines with high bleed-back (generally above 600 ml) and high head pressure may require the <br /> 99 LD-2000\E to pass a field test for annual certification. Consult with factory before ordering and installing <br /> the 99 LD-2000\E. <br /> Electronic line Leak Detection Upgrade! <br /> The 99 LD-2000 may be upgraded in the field to eliminate thermal induced slow-flow, provide submersible <br /> shut-down, and alarm notification to site monitoring equipment. Request information on the ISM-40,80,an easy <br /> upgrade for existing or new installations. The ISM-4.080 also stages turbines and controls solenoid valves for <br /> loading racks and marine applications. If there is no need for staged turbines, solenoid valve control. alarm <br /> notification or submersible shut-down, request information on the ARM-4073 to eliminate false alarms only_ <br /> 5.000 � / <br />
