Irrigation第 23 / 100 题
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
b.The color of the turf
c.The soil pH level
d.The air temperature
解析
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.
