Vaporless Mfg. LD 3000/3000S <br /> Accuracy of Detection <br /> The Vaporless LD 3000 AND LD3000S leak detector was correct in its determination of <br /> a leak for all 9 of the 3gal/h leak tests under different temperature conditions. <br /> Accuracy of False Alarm <br /> The LD 3000 AND LD3000S was correct in its determination of a tight pipeline for all 9 <br /> of the tight tests under different temperature conditions. <br /> Maximum Pipeline Size, Flexible Pipe <br /> The EPA allows for line leak detectors to be used on flexible pipelines containing up to <br /> 200% of the pipeline volume that they were evaluated on. However, the volume of any <br /> rigid line that is connected to the flexible line branch cannot be included in the test <br /> pipeline's volume. The LD 3000 was evaluated on a flexible pipeline that was 130 feet <br /> in length by 3-inches in diameter plus rigid pipe that was 30-feet in length by 3.125- <br /> inches in diameter. While the total volume of the line as tested was 60 gallons, only the <br /> volume of the flex line, 48 gallons, by itself can be included in the calculations for the <br /> maximum line size. Applying the EPA protocol limitations to the LD 3000 and LD 3000S <br /> leak detectors, the results of this evaluation would apply to flexible pipelines having a <br /> maximum volume of 96 gallons. <br /> Maximum Line Size, Rigid Pipe <br /> The EPA allows for line leak detectors to be used on rigid pipelines containing up to <br /> twice the volume that they were evaluated on. During this testing, the Vaporless LD <br /> 3000 was evaluated on a FRP line consisting of a total of 180 ft of 3.125 inch diameter <br /> FRP and 200 ft of 4 inch diameter FRP with a combined volume of 202 gallons. <br /> Applying the EPA protocol value of 200% of the test pipeline size, the LD 3000 AND <br /> LD3000S can be used on pipelines up to 404 gallons. <br /> Maximum Pipeline Size, Combined Rigid and Flexible Pipe <br /> As discussed above, the EPA protocol does not allow the volume of rigid piping used in <br /> a flexible piping branch to be used in the maximum pipeline volume calculation. In this <br /> evaluation using one branch of flexible piping and one branch of rigid piping, combining <br /> the individual limitations of 96 and 404 gallons respectively gives a 500 gallons <br /> maximum volume for piping systems combined. <br /> Time to Conduct a Test <br /> All of the tests were completed in less than one minute. <br /> Waiting Times <br /> Waiting times after the delivery of product, after product is circulated through the line or <br /> after pumping has stopped are not necessary before valid tests can be conducted. All <br /> of the tests were conducted immediately after product circulation through the pipeline <br /> was stopped. <br /> Page 7 of 8 <br />
