Vaporless Mfg. LD 3000/3000S <br /> 2.0 Description of the Testing Location & Equipment <br /> The Vaporless Manufacturing LD 3000/LD 3000S was evaluated at the Fuels <br /> Management Research Center located in Grain Valley, Missouri, which is operated by <br /> Ken Wilcox Associates, Inc. Three different pipeline configurations were tested during <br /> the evaluation. <br /> The evaluation system consisted of: <br /> • A 600 gallon steel product tank containing gasoline that was kept at <br /> predetermined temperature by an external heat exchanger. <br /> • A 1% HP submersible turbine pump (STP), controlled by a dispenser switch <br /> and used to circulate the gasoline through the piping system and to house the <br /> Vaporless LD 3000 leak detector. <br /> • A 30' long X 3%" diameter FRP rigid pipe that led from the pump to the <br /> junction of two branches of large diameter pipes used for the evaluation. One <br /> branch was a 200' long X 4" diameter FRP rigid pipe connected by a 150' <br /> long X 3%" diameter FRP rigid pipe back to the product tank. The other <br /> branch was a 130' long X 3" diameter flexible pipe that ran back to the <br /> product tank. Both branches of piping had valves at the pump end and <br /> dispensing end, allowing them to be isolated from each other or ran <br /> simultaneously. <br /> • Thermocouples were used to measure gasoline temperature. The fuel <br /> temperature in the tank was obtained from the tank gauge that was <br /> permanently installed in the tank. Three thermocouples were used to <br /> measure soil temperature at 2", 4", and 12" from the piping per the EPA <br /> protocol. The product tank temperature and weighted soil temperature were <br /> used to compute the temperature differential. <br /> A length and volume summary of the piping configurations is provided in Table 1. <br /> Table 1.
