4. What is the nominal diameter of a pipeline that can be tested with this system? (X) 1 in. or less (X)between 1 and 3 in. (X)between 3 and 6 in. ( )between 6 and 10 in. ( ) other 5. The system can be used on pipelines pressurized to 50 psi. The safe maximum operating pressure for this system is 250 psi. 6. Does the system conduct a test while a mechanical line leak detector is in place in the pipeline? (X)yes ( ) no General Features of the System 7. What type of test is the system conducting? (Check all applicable responses.) (X) 0.1 gal/h Line Tightness Test (X) 0.2 gal/h Monthly Monitoring Test' (X) 3 gal/h Hourly Test 2 8. Is the system permanently installed on the pipeline? (X)yes ( ) no Does the system test the line automatically? (X)yes ( ) no If a leak is declared,what does the system do? (Check all applicable responses.) (X) displays or prints a message (X)triggers an alarm (X) alerts the operator (X) shuts down the dispensing system 9. What quantity or quantities are measured by the system?(Please list.) Volume and time 1 Monthly Monitoring for 0.2 gal/h leaks was not tested by KWA,Inc. Tests with leak rates of 0.1 gal/h were simulated and were detected by the system when the threshold was set at 0.068 gal/h. The system correctly identified 100%of the 0.1 gal/h leak simulations and it is therefore assumed that the system will correctly identify 0.2 gal/h leaks using a threshold of 0.136 gal/h. 2 Three previous evaluations were conducted on versions of the LD-2000 for Hourly Testing. Evaluation reports written by KWA,Inc. for the following models of the LD-2000 are available from Vaporless Manufacturing: LD-2000 and LD-20005, 11/19/90;LD-2000E and LD-2000E-S, 12/11/92;LD-2000T and LD-2000T-S,7/13/93.
