FS Series Flow Sensors

Compatible with IQ3, IQ4, Maxicom, SiteControl, LINK, Site SAT, ESP- LXD, LXME2 PRO, LXMEF, ESP-ME3 and LX-IVM Controllers

Rain Bird FS Series flow sensors use impellers to sense flow and send flow rate 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 from controllers and central control. Use Rain Bird Flow Sensors with Rain Bird Maxicom², SiteControl and IQ central control applications, or in standalone systems using Rain Bird ESP-LXIVM, ESP-LXIVM PRO, ESP-LXD, ESP-LXME2 PRO and ESP-LXMEF controllers.


Flow Sensor Features
Simple six-bladed impeller design
Designed for outdoor or underground applications
Available in PVC, brass, or stainless steel construction
Pre-installed in tee or saddle mounted insert versions
Flow Sensors Enable Key LX Series Controller Features
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
Using With Transmitters and Pulse Decoders
Programmable from a computer (PT322 – Maxicom and SiteControl Systems only – not required for ESP-LXMEF or ESP-LXD)
Reliable solid-state design, available with or without LCD display
Operates with MAXILink,™ and (hard-wire) two-wire satellite systems
Easy-to-program, menu-driven design
Mounted in optional NEMA enclosure (PT5002 only)

For ESP-LXIVM Two-Wire Systems: the Flow Sensor is installed with a Two-Wire Sensor Device (LXIVMSEN)
For ESP-LXD Decoder Systems: the Flow Sensor is installed with a Two-Wire Decoder Sensor Decoder (SD211TURF) (Previously SD210TURF)
For ESP-LXMEF Systems: the Flow Sensor is attached to the FSM-LXME Flow Smart Module
For (Hard Wire) Two-Wire Satellite Systems (Maxicom²® and SiteControl): the Flow Sensor is installed with a Pulse Transmitter and a Rain Bird Pulse Decoder (DECPULLR)
For Link Radio Satellite Systems (Maxicom² and SiteControl): the Flow Sensor is installed with a Pulse Transmitter (no pulse decoder required)
For ESP-SITE Satellite Systems (Maxicom): the Flow Sensor is installed with a Pulse Transmitter (no decoder required)
For SiteControl Decoder Systems: the Flow Sensor is installed with a Two-Wire Decoder Sensor Decoder (SD211TURF) (Previously SD210TURF)
*Surge protection (FSSURGEKIT) is recommended for Maxicom and SiteControl systems – One at the Pulse Transmitter, and if more than 50’ of wire run, one at the Flow Sensor. FSSURGEKIT is not compatible with ESP-LXMEF and ESP-LXD Controllers
