A lawn sprinkler flow meter maintains specific environmental conditions for residential lawns and other grassy areas. Sprinkler flow meters can also be used in smart home applications to automate routines based on system flow rate requirements. By installing sprinkler flow sensors, water usage can be monitored and runoff reduced.

Upon installation, the sprinkler flow sensor measures irrigation flow to determine water speed through the system. The meter then sends this information to an irrigation controller, which can detect issues and conserve water. Suppose the water flow rate is too high. In that case, the flow meter sends a signal to the irrigation controller to take corrective measures, such as stopping the water flow, sounding an alarm, or sending an alert message.
