What is the primary function of an Automatic Tank Gauge (ATG)?

The primary function of an Automatic Tank Gauge (ATG) is to continuously monitor fuel levels and detect leaks. An ATG is a crucial component of underground storage tank (UST) systems, as it provides real-time information about the volume of fuel stored in the tank as well as effectively monitoring for any discrepancies that could indicate a leak. By measuring the height of the product within the tank, the ATG can provide accurate readings of tank levels. Additionally, it can also run tests to detect leaks in the tank and connected piping, ensuring compliance with environmental regulations and protecting groundwater from contamination.

This functionality is essential because it allows operators to maintain the integrity of the fuel storage system while ensuring safety and environmental protection. Regular monitoring helps in establishing that tanks are operating within normal parameters and that any potential leaks are identified and addressed promptly. Other options may involve related functions but do not encompass the primary role of an ATG as comprehensively as monitoring fuel levels and detecting leaks does.
