Don't let the exterior deceive ' u! What you see is not what you have been getting! . <br />Beneath this familiar exterior is the greatest imprbvenzent in mechanical line Ieak <br />detection since 1990—the year Vaporless Manufacturing; Inc: integrated. a line <br />check valve/pressure relief into the body of a mechanical Iine leak detector and <br />pioneered the single piston design in the original LD-2000'. <br />The 98.. LD-2000 significantly raises. the. performance standard by which all future <br />mechanical leak detectors. will be judged: The 98 ID-2000' s .upgradable.to line <br />leak. detection with thresholds 'of .2 GPH monthly .and :1 G.PH annual Line leak . <br />detection standards, using theYaporless PLC=5000 interface.: <br />Years of fleM use have proven the' LD-2000!96 LD-2000.series 'of <br />detectors to -be 1he most effective -mechanicalleak- detectors to: (a)- overcome <br />thermal contraction, (b) provide the- longest field performance, averaging 4+ <br />years (and growing) mean time to failure, functioning within EPA 3 GPI <br />14°psi. leak threshold, (c} reduce pump service .calls due to failed submersible <br />check valve failure, (d) to provide the' best guarantee** for leak detectors <br />available. The 98 LD-2000 exceeds the performance ofall previous LD-2000'models. <br />Unlike anything available from any other .manufacturer of mechanical leak <br />detectors, the 98 LD-2000: <br />1. Drastically reduces the piston size of the leak detector: <br />In fact,this new series of leak detectors has 78% less surface ' . <br />area than competitive equipment. <br />2. Eliminates the traditional fuel flow path to the piston (which controls leak. . <br />sense -full flow performance). This allows the leak detector metering system <br />better isolation from the turbulence and hydraulic effects found in the pump <br />head during pump startup. This fuel flow change also eliminates the <br />mechanical and thermal. effects present in the upper half of the pump, allowing <br />the leak detector to only respond to line pressure changes: <br />
