Rain Bird FS100B 1 in. Brass Tee Flow Sensor

Rain Bird flow sensors send flow data to central control or stand-alone controller systems for precise and accurate flow monitoring. Rain Bird flow sensors are available with NPT and BSP ends.

Rain Bird flow sensors enable you to capitalize on the advantages of Flow Management functionality. Use Rain Bird Flow Sensors with Rain Bird Maxicom2, SiteControl and IQ v2.0 central control applications or in standalone systems using Rain Bird ESP-LXD, ESP-LXME and ESP-LXMEF controllers to benefit from:

Features & Benefits

  • Flo-Watch™. Flo-Watch constantly monitors for low flow and excess flow conditions caused by broken lines or heads, automatically quarantines and shuts down the problem area and continues to irrigate non affected areas. Saves water, saves plant material and enables irrigation programs to continue and complete.
  • Learned Flow. The controller automatically learns station flow rates resulting in more accurate flow rates. The automatic collection prevents you from having to manually enter data from drawings or physically visiting each valve to collect flow data and manually entering the data into a controller.
  • FloManager®. FloManager determines the optimal station irrigating sequence. The system runs at its fullest capacity until programs are complete. The controller automatically selects and runs multiple valves at the same time within hydraulic parameters allowing for shorter water windows.

Features (Sensors)

  • Simple six-bladed impeller design
  • Designed for outdoor or underground applications
  • Available in PVC, brass or stainless steel construction
  • Available in NPT and BSP ends
  • Pre-installed in tee or insert versions

Features (Transmitters)

  • Reliable solid-state design
  • Display or signal-alone versions
  • Easy-to-program, menu-driven design
  • Programmable from a laptop computer (PT322)
  • Operates with both MAXILink™ and (hard wire) two-wire satellite systems
  • Mounted in optional NEMA enclosure (3002 only)

Suggested Operating Range

The following table indicates the suggested flow range for Rain Bird Flow Sensors. Rain Bird Sensors will operate both above and below the indicated flow rate. However, good design practice dictates the use of this range for best performance. Sensors should be sized for flow rather than pipe size.

  • Temperature: 220° F (105° C) (max) on metal models; 140° F (60° C) (max) on plastic models

Electrical Specifications (Transmitters)

  • Input required:
    12-30 VDC/VAC on PT322
    12-24 VDC on PT 3002
