The Irritrol FS-B100 is a 1" tee-mounted flow sensor designed for professional irrigation systems. Engineered for reliable flow monitoring, the FS-B100 reports real-time flow to compatible Rain Master and Sentar II controllers so the system can detect leaks, line breaks, or abnormal flows and shut down the master valve to protect landscaping and irrigation piping.

  • Connection: 1" NPT female pipe connection for direct tee installation.
  • Body: Cast brass tee designed for long-term field use and corrosion resistance.
  • Flow range: Recommended operating range 2–40 GPM; use manufacturer calibration tables for accuracy.
  • Pressure rating: Rated for up to 400 psi maximum working pressure when installed and calibrated per manufacturer guidance.
  • Calibration & compatibility: Requires field calibration; compatible with Rain Master Eagle and Sentar II controllers for flow limit checking and automatic shutdown.
  • Performance: K-value 109 and offset 27 (use controller tables for precise settings and station-level limits).

This sensor is intended for professional irrigation use and must be installed by a qualified technician following local codes. Field calibration is required for accurate flow measurement and limit checking; manufacturer documentation and sell sheets provide calibration tables and wiring diagrams. Replacement parts, installation instructions, and support are available from the product manufacturer and authorized distributors.
