The check valve also maintains <br /> line pressure. sufficient to allow dispensation of fuel immediately, providing that the down- <br /> stream dispensing line has no leak. <br /> FE^Tupis <br /> • Maintains pressure in the delivery line when no leak is present <br /> • Detects leaks even if substantial hydrostatic shock occurs in the dispensing line <br /> f Reduces unscheduled pump maintenance due to check valve deterioration or <br /> functionai element deterioration <br /> • Provides improved performance under extreme climatic conditions <br /> • Sees a leak of 3 GPH or smatter at 10 psi for a full 18 months after date of installation- <br /> guaranteed <br /> • Overcomes problems caused by thermal contraction and line resiliency in larger <br /> delivery systems <br /> TESr RJESUL - A nationally-recognized independent environmental consulting firm <br /> conducted twice the mandated number of EPA protocol tests on the LD-2040. Here is what <br /> they found: <br /> o The LD-2000 exceeds the EPA regulations that require detection of a 3 GPH leak at 10 psi <br /> with a detection probability of 95% and a false alarm probability of 5%. Under conditions <br /> of thermal expansion or contraction, the LD-2000 is capable of detecting a 3 GPH leak with <br /> a probability of detection of 100% and a false alarm probability of 0%. <br /> Under neutral test conditions, the LD-2000 detected leaks under 2 GPH <br /> ® From pump start-up, the average leak sensing time to full flow was less than 5 seconds. <br /> • 125 ml vapor resiliency was added to the line system with no failures <br /> • The LD-2000 detected leaks in the pipe system up to 10' above the leak detector. This test. <br /> called a "Head Pressure Reset Test," erasures that all buried pipe is protected. <br /> S d ZLZZ EZ9 OZS l ONIineib1SI4 SNV HOdA WdOO:V L66l-09—L <br />
