PLC-5000 Site Controller, LD-2000 and LD-2000 PLC <br /> Table 2. Performance Parameters for the Vaporless PLC-5000 Site Controller <br /> with Automatic Electronic Line Leak Detection and the 98 LD-2000 <br /> and 98 LD-2000 PLC <br /> Parameter Value <br /> Abbreviated Hourly Testing (3.0 gal/h leaks) <br /> Threshold 2.5 gal/h <br /> Probability of Detection (PD) 100% <br /> Probability of False Alarm (PFA) 0% <br /> Test Times with 3.0 gal/hr leak Range: 1 to 8 minutes <br /> Test Times without leak Range: < 1 minute <br /> Monthly Monitoring/Annual Line Tightness Testing (0.1 gal/h leaks) <br /> Threshold a 0.068 gal/h <br /> Probability of Detection (PD) 100% <br /> Probability of False Alarm (PFA) 0% <br /> Test Times with 0.1 gal/hr Leak Range: 3.5 to 9.2 hours <br /> Average: 6 hours <br /> Test Times without Leak Range: 1.8 to 10.9 hours <br /> Average: 5.3 hours <br /> Maximum Rigid Pipeline Size 400 ft of 3.25 in diameter <br /> line or 172 gal volume <br /> Maximum Flexible Pipeline Size 415 ft of 1.5 in diameter <br /> line or 39.5 gal volume <br /> Waiting Time After Delivery of <br /> Product Before Conducting a Test None Required <br /> Waiting Time After Product Circulation <br /> Through Line Before Conducting a Test None Required <br /> 8 The commercial version of the system will provide Monthly Monitoring for 0.2 gal/h leaks using <br /> a threshold at 0.136 gal/h. However, Monthly Monitoring for 0.2 gal/h leaks was not tested by KWA, Inc. <br /> Tests with leak rates of 0.1 gal/h were simulated and were detected by the system when the threshold <br /> was set at 0.068 gal/h. The system correctly identified 100% of the 0.1 gal/h leak simulations and it is <br /> therefore assumed that the system will correctly identify 0.2 gal/h leaks using a threshold of 0.136 gal/h. <br /> Page 10 <br />
