ATG equipment that tests for loss of product and conducts inventory control must detect a leak rate of what?

• A. 0.1
• B. 0.2
• C. 0.5
• D. 1.0

Answer: (B)

ATG equipment is used to track actual inventory against what should be in the tank and to flag any losses that might indicate a leak. The leak-rate sensitivity determines when an alarm is triggered. The best choice is a leak rate of 0.2 percent of the tank’s capacity per day because it strikes a balance: small leaks are detected early to protect inventory and stay compliant, while a rate this low avoids too many false alarms caused by ordinary fluctuations like temperature changes or gauge noise. If the threshold were much lower, alarms would fire too often; if it were higher, smaller leaks could go undetected. So, 0.2 percent per day is the most practical, reliable setting for leak detection in this context.
