Rain Bird Ultrasonic Flow Sensor - UFS Series

  • 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.

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.

Frequently Asked Questions

What pipe sizes and flow ranges do UFS models support?
UFS100, UFS150 and UFS200 cover approximately 0.3–50, 0.5–110, and 1.0–200 GPM respectively.
How should I position the UFS sensor when installing?
Install the sensor immediately after a bend or valve — no straight-run required. Use a jumbo valve box for easiest fit and follow the controller wiring guide.
Can the sensor remain installed during winter blowout?
Yes. The solid-state, no-moving-parts design permits blowout with the sensor installed; follow surge-protection guidance for satellite systems.
