California ICC UST Inspector Practice Exam

Which components can an automatic leak detection system include?

1. Pressure sensors

2. Flow meters

3. Both pressure sensors and flow meters

4. Only visual indicators

The correct answer is: Both pressure sensors and flow meters

An automatic leak detection system is designed to identify leaks in underground storage tanks (USTs) quickly and effectively, thereby ensuring environmental safety and compliance with regulations. Such systems can utilize a combination of various components to enhance their reliability and accuracy. Pressure sensors are crucial as they monitor the pressure within the tank and the associated piping systems. A drop in pressure can indicate a leak, prompting further investigation. These sensors provide real-time data that can quickly identify potential failures before they become significant problems. Flow meters, on the other hand, measure the flow rate of the fluid within the system. If there is an unexpected change in flow patterns, such as a decrease in the amount of product being delivered or dispensed, this could signal a leak or an unauthorized release of product. By comparing the expected flow with the actual flow, flow meters can help in identifying anomalies that may indicate a leak. Utilizing both pressure sensors and flow meters provides a comprehensive approach to leak detection. This combination allows for cross-validation of data, increasing the system’s effectiveness in detecting leaks early. Thus, the inclusion of both components in an automatic leak detection system makes for a robust solution that meets safety standards and helps protect the environment.
