WFS Support

The Hunter WFS allows flow-capable controllers, such as the Hunter ACC and I-Core, to monitor actual flow in irrigation systems wirelessly.

With proper setup at the controller, this allows the controller to record and report actual flow in liters or gallons. Flow-learning controllers can also use WFS to learn typical flow for each zone of irrigation, and monitor during watering for high and low flow conditions.

WFS equips controllers to respond on their own to incorrect system performance, preventing damage to landscape and wasted water resources. 

  • Components
    This section will give you a brief overview of some of the components of the WFS.SensorImpeller: Rotates when flow is occurringO-rings: Provides sealing of sensor in sensor
  • System Overview and Operation
    The WFS is typically installed near the point of connection, in an appropriately-sized FCT tee. The WFS transmitter can connect to a host controller up to 500 ft/150 m
  • Installing the WFS sensor and FCT tee
    The WFS sensor is designed to install within an FCT tee fitting. See chart below for tee sizes and corresponding pipe diameters. HFS FCT Tee Fitting Models (All tees are

  • Installing the WFS sensor into the FCT fitting
    The FCT tee fitting comes with a plug that allows for installation of the FCT into the irrigation system prior to installing the sensor. This allows the FCT tee to be installed

  • Pairing the sensor and receiver
    After applying power to either the sensor/transmitter or receiver, wait a minimum of 10 seconds for the power up sequence to complete. During this time there will be one or more
  • Dip Switch Settings
    The dipswitch settings must match for the Transmitter and Receiver to communicate properly.  The default setting is with all dipswitches set to the OFF position. The
  • Operating Performance
    When flow is occurring the sensor/transmitter will transmit sensor information at a maximum rate (depending on flow) of once every 5 seconds. The receiver LED will flash green at
  • System Considerations
    Working with WFS Hunter flow-capable controllers are designed to measure and record actual flow, shut off irrigation when a high flow condition occurs, and identify which
  • Winterization
    Flow sensors can potentially be damaged by winterization blow-out techniques, and should be removed prior to injecting compressed air into the pipes. WFS sensors are installed
