Ameron Dualoy° Pipe Monitoring System 4.0 TEST RESULTS AND CALCULATIONS The results of this testing were used to determine if the operating conditions in an installed line are likely to produce a false alarm. The problem of a missed detection is much less likely as the test times for producing an alarm with a relatively small leak are short. Any leak of measurable rate will eventually produce an alarm, probably in less than one day, before any product is lost to the environment. If the measurements in level change in the reservoir are small under the test conditions, the probability of a false alarm is low. The test results for this evaluation are summarized in Table 1 listing all of the important parameters measured in this evaluation. Table 1.

The initial brine level is assumed to be near the midpoint of the sensor spacing. Primary Pipe Pressure Test Pressurization of the primary pipe produces a slight increase in the brine level. The results of the pressure test are provided in Figure D-1 in Appendix D. The trend is for the level to increase slightly as the pressure in the primary pipe is increased as was expected. The regression line for both tests gives a slope of 0.0002 inches per psi of pressure applied. The maximum observed range of level changes for the highest and lowest points were 0.125 for the first test and 0.095 inches for the second test. Using the worst-case conditions, the level change per psi is 0.00125 inches per psi for the 21 ft test line. If a linear extrapolation of the worst-case conditions (0.125 in/100 psi for a 21 ft pipeline) to a pressure of 30 psi in a pipe of 300 ft in length, the level increase would be expected to be approximately 0.54 inches, well below the change required to produce an alarm in a properly designed system. Since the pressure change of 100 psig is considerably larger than would normally be expected for a typical service station, the effects of pressure are minimal for the Ameron pipeline system.
