Rain Bird FS100P 1" PVC Tee Flow Sensor for Irrigation - FS100P

Rain Bird FS100P 1" PVC Tee Flow Sensor for Irrigation - FS100P

Rain Bird FS100P 1" PVC Tee Flow Sensor provides reliable flow monitoring for irrigation systems. Its compact PVC tee body houses a simple six-blade impeller that senses flow and sends pulse data to controllers for accurate, real-time monitoring.

Included documentation (tech specs, installation, transmitter manuals, troubleshooting) helps with correct setup and calibration. Use the appropriate pulse transmitter or decoder as required by your control system. For professional installation, follow the Rain Bird manuals and local codes.
