Automatic Tank Gauging (ATG) systems are indeed capable of alarming the operator in the event of a low product level. These systems are designed to monitor various parameters of underground storage tanks (USTs), including the level of the product within the tank. When the product level drops below a predefined threshold, which is set to help prevent potential operational issues or environmental hazards, the ATG system generates an alarm.

This capability enhances safety by allowing operators to take timely actions, such as refilling the tank or investigating potential leaks, thereby mitigating risks associated with low product levels. This is particularly important in maintaining compliance with regulations and ensuring environmental protection.

While the alarm features may vary based on the technology and model, the general function of notifying operators about low product levels is a standard feature across both modern and certain legacy ATG systems.
