It has been tested according <br /> to the U.S. Environmental Protection Agency A) protocol "Standard Test Procedures for <br /> Evaluating Leak Detection Methods: Pipeline Leak Detection Systems" as an hourly monitoring <br /> device. The results show that the D exceeds the performance requirements of the EPA <br /> for hourly line leak detection systems It is capable of detecting leak rates of 3 /hr with a <br /> probability of detection of 1009x' and a probability of false alarm of 096. Under stable conditions, <br /> the -MLD may detect leaks as small as 2 gal/hr. <br /> The testing was conducted on a 3-in diameter by 176 ft long fiberglass line (64.6 gal) <br /> which means that the is approved for lines up to 129.2 gal capacity. <br /> iii <br />
