Rain Bird Ultrasonic Flow Sensor - UFS Series 1.5 & 2 in - UFS150
Designed for professional irrigation systems, the UFS Series gives accurate real-time flow and totalized readings to protect landscapes and optimize watering windows. Surge protection is recommended for satellite or Maxicom/SiteControl systems; consult the user guide for wiring and configuration details.
Features
- No straight-pipe requirement: install immediately after a bend or valve; jumbo valve box recommended for easiest fit.
- Wide flow range across models: UFS100 0.3-50 GPM, UFS150 0.5-110 GPM, UFS200 1.0-200 GPM with ±2% accuracy across each range.
- Solid-state ultrasonic sensing with no moving parts for reliable, low-maintenance operation and allowed blowout during winterization.
- Durable construction: glass-filled nylon body, pressure-rated to 200 PSI, electronics rated IP68 / NEMA 4X for outdoor or underground use.
- On-board LED diagnostics indicate power, full-pipe status, forward/reverse flow; simple controller setup with preprogrammed K and offset values.
- Integrates with Rain Bird controllers and transmitters (PT322, PT5002) and supports pulse output, Flo-Watch leak detection, Learned Flow, and FloManager sequencing.
