Rain Bird FG100 Flow Sensor

The Rain Bird FG100 is an in-line flow sensor for monitoring irrigation-system flow. When connected to a compatible Rain Bird controller, it can help identify abnormal flow caused by leaks or damaged pipework.

Compatibility and installation

The FG100 can be used with compatible Rain Bird controllers, including ESP-ME3 installations equipped for flow monitoring and supported LX Series controllers. Standard 18 AWG irrigation wire may be used for runs up to 152.4 m; use shielded cable where electrical interference may be present.

Important: Install in the correct flow direction and confirm controller compatibility before ordering. Size the sensor to the expected system flow, not only the pipe diameter.
