A flow sensor connected to a smart controller is MOST useful for detecting what problem?
a.A broken lateral line or stuck valve causing abnormal flow

c.The soil pH level
d.The air temperature
Giải thích
A flow sensor measures real-time water flow and lets the controller compare it to expected values for each zone. Abnormally high flow signals a broken pipe or stuck-open valve, and the controller can shut the system down to prevent water loss. This protects against costly leaks and water waste.
