An automatic tank gauge is utilized for leak detection of which component?

1. Tank

2. Tank and Piping

3. Piping

4. Interstitial space

The correct answer is: Tank

An automatic tank gauge is primarily designed to monitor the liquid levels within a tank and can also provide data on the amount of inventory present. Its core function is to detect leaks specifically within the tank itself. It achieves this through continuous monitoring, allowing the system to identify discrepancies in expected versus actual fluid levels that may indicate a leak. While some automatic tank gauges have capabilities to monitor the interstitial space or piping, their primary use for leak detection is centered on the tank as a containment component. This important distinction is why the correct answer focuses solely on the tank's role in leak detection rather than expanding to the additional components, which might involve different monitoring systems or technologies.
