California UST System Operator Practice Test

Can automatic tank gauging be performed on piping?

1. Yes

2. No

3. Only in emergencies

4. Only for tanks

The correct answer is: No

Automatic tank gauging (ATG) systems are specifically designed to monitor the liquid levels within tanks, not piping. The purpose of ATG is to provide accurate inventory control, detect leaks, and monitor product levels, which are all functions that pertain to the tank itself. While there may be monitoring systems capable of checking for leaks in the piping connected to the tank, they do not fall under the umbrella of ATG systems, which focus solely on tanks. Typically, the piping system utilizes other monitoring methods such as pressure sensors, flow meters, or other leak detection systems that comply with regulatory requirements for underground storage tanks (USTs). These systems ensure the integrity and safety of the entire UST system by providing relevant data specific to the functions they are designed to monitor. Thus, the statement regarding the applicability of automatic tank gauging to piping is not accurate, leading to the conclusion that ATG cannot be performed on piping.
