What leak rate is the automatic line leak detector designed to detect?

• A. 1 gallon per hour
• B. 3 gallons per hour
• C. 2 gallons per hour
• D. 5 gallons per hour

Answer: (B)

The automatic line leak detector is calibrated to notice leaks at a specific rate, so the test can reliably separate acceptable conditions from what needs repair. It’s set to detect leaks at three gallons per hour. That means if the product line is leaking at that rate or more, the detector will trigger a leak indication, and the line tightness test would fail until the leak is fixed. A rate of one or two gallons per hour would make the detector too sensitive and prone to nuisance alarms, while five gallons per hour would miss smaller leaks that the test is meant to catch. So, three gallons per hour is the designed detection threshold for the ALLD.
