Which tool can be used to help determine if there is a leak in the irrigation system?

1. Pressure gauge

2. Flow sensor

3. Water meter

4. Soil moisture sensor

The correct answer is: Water meter

The water meter is an effective tool for detecting leaks in an irrigation system. It measures the volume of water that flows through the system, allowing the user to monitor water usage closely. When there is a significant and unexplained increase in water consumption, it can indicate a leak somewhere within the system. By comparing readings over time, if the meter continues to register usage when the system should be off, it strongly suggests that there is an active leak. The other tools mentioned serve different purposes, such as managing and measuring water pressure (pressure gauge), monitoring real-time flow rates (flow sensor), and assessing soil moisture levels (soil moisture sensor). While they play crucial roles in the overall irrigation management and efficiency, they are not specifically designed to pinpoint leaks in the system like a water meter. Thus, the water meter's ability to track total water usage makes it the most suitable choice for identifying potential leaks.
