Vaporless 99 LD-2000 Addendum <br /> 1.0 Introduction <br /> This report contains the results of testing conducted on the 99 LD-2000. A limited <br /> number of tests were conducted which were designed to verify that the 99 LD-2000 could <br /> detect a 3 gal/h leak in the same manner as the original LD 2000 mechanical line leak <br /> detector. Testing was performed in accordance with the EPA Pipeline Leak Detection <br /> Test Protocoll with the exception of the number of tests performed 2 <br /> This report is to be used in conjunction with the November 19, 1990 evaluation of the <br /> Vaporless LD 2000 mechanical line leak detector.3 Several evaluations have been <br /> conducted on various LD 2000 models to determine performance parameters! The <br /> original LD 2000 evaluation (November 19, 1990) was conducted on a rigid pipeline that <br /> was 176 ft. in length by 3 3/8 inches in diameter with a volume of 81.5 gallons. The <br /> results of the testing determined that the LD 2000 had an estimated probability of <br /> detection (PD)of 100% with an upper confidence interval of 92 to 100% and an estimated <br /> probability of false alarm (PFA) of 0%with a lower confidence limit of 0 to 8%. <br /> 1 "Standard Test Procedures for Evaluating Leak Detection Methods: Pressurized <br /> Pipeline Leak Detection Systems", EPA/530/UST-90/010, September, 1990. <br /> 2 The EPA protocol requires that 50 tests be conducted under various conditions <br /> for a full evaluation. This evaluation consisted of 6 tests on a rigid line and 6 tests on a <br /> flexible line. <br /> 3 Performance Evaluation of the Vaporless LD 2000 Line Leak Detector, Final <br /> Report,For Vaporless Manufacturing,November 19, 1990, Ken Wilcox Associates, Inc. <br /> 4 Three previous evaluations were conducted on versions of the LD-2000 for <br /> Hourly Testing.
