Spec Sheet Install Manual
Rain Bird Ultrasonic Flow Sensors (UFS) represent the best in flow sensing technology for irrigation, sending flow data to central control or stand-alone controller systems for precise and accurate flow monitoring. Utilizing ultrasonic waves, the UFS Series offers superior flow range capability, as well as other advantages such as not being subject to typical straight-pipe requirements that limit the physical placement of flow sensors on an irrigation system plan.
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 central control applications, or in standalone systems using Rain Bird ESP-LXD, ESP-LXME2 Pro, and ESP-LXMEF controllers.
Ultrasonic Flow Sensors are available with NPT threading.
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
Sensor Features
- Uses internal ultrasonic transducers and acoustical reflectors to sense flow
- Designed for outdoor or underground applications (upper electronics are IP 68 / NEMA 4X rated)
- Glass Filled Nylon body construction for high pressure rating (200 PSI)
- No straight-pipe requirements - can be placed right next to a valve
Flow Range
- UFS200 - 1.0 - 200 GPM
- UFS150 - 0.5 - 110 GPM
- UFS100 - 0.3 - 50 GPM
Sensors
- Accuracy: +/- 2% across full flow range
- Velocity: 2-20 Feet (0.6-6.1 meters) per second depending on model and system specifications
- Pressure: 200 PSI Working Pressure
- Temperature: 32° - 150° F (0° - °65 C)Working Temperature
Configuration
- 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 (SD210TURF)
- For ESP-LXME2 PRO Systems: the Flow Sensor is attached to the flow terminals on the FSM-LXME2 PRO Base Module
- For ESP-LXME 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 (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
Dimensions
- Length: 10 1/2”
- Depth: 4 3/4”
- Height: 4 7/8”
