What is the function of Automatic Tank Gauging Systems in underground storage tank monitoring?

1. Detect surface leaks

2. Measure tank inventory levels

3. Prevent overfilling

4. Control fuel dispensing

The correct answer is: Measure tank inventory levels

Automatic Tank Gauging Systems (ATGS) are primarily designed to measure tank inventory levels accurately. They utilize various technologies, such as sensors and software, to continuously monitor the amount of liquid in an underground storage tank. This information is essential for ensuring compliance with regulations, managing fuel supplies efficiently, and preventing potential environmental hazards. By providing real-time data on the inventory levels, ATGS helps operators gauge how much product is available for use and can alert them to discrepancies that might indicate leaks or other issues. Accurate measurement of tank levels is crucial for maintaining operational efficiency, managing deliveries, and planning for replenishment of the tank’s contents. While ATGS can play a role in enhanced safety and can support leak detection systems, their primary function is centered around inventory management, making the measurement of tank inventory levels the correct focus in this context.
