What is the role of a fuel oil monitoring system?

The role of a fuel oil monitoring system is primarily to provide real-time data about tank levels and potential leaks. This is crucial for ensuring safety and compliance with regulations. By continuously monitoring the levels of fuel oil in storage tanks, the system can alert operators to any discrepancies or unusual changes that indicate a leak may be occurring. These capabilities help prevent environmental contamination, reduce the risk of spills, and ensure that fuel can be managed efficiently.

In addition, having real-time updates on tank levels allows for better inventory management and can help prevent overfilling, which is another important safety consideration. Overall, the monitoring system plays a vital role in the safe storage and handling of fuel oil, making option B the most accurate description of its purpose.
