Flow-Sync / Flow-Clik Support

Welcome to the Flow-Sync sensor support section.   The Flow-Sync or HFS is a sensor that monitors the flow of water running through a pipe, when flow is at an abnormal level the Flow-Sync and controller communicate to shut off the irrigation.  In this section you will find instructions on how to specify, install and troubleshoot a Flow-Sync sensor.

  • Introduction
    The Hunter Flow-Sync allows flow-capable controllers, such as the Hunter ACC and I-Core, to monitor actual flow in irrigation systems. With proper setup at the controller, this
  • Components
    This section will give you a brief overview of some of the components of the Flow-Sync system.
  • System Overview
    Flow-Sync is typically installed near the point of connection, in an appropriately-sized FCT Tee. Flow-Sync can connect to the host controller via two direct burial-rated 18 AWG
  • System Considerations
    Working With Flow-Sync Hunter flow-capable controllers are designed to measure and record actual flow, shut off irrigation when a high flow condition occurs, and identify which
  • Ideal Location
    The Hunter Flow Sensor body (FCT or Flow Clik Tee) is designed in diameters from 1" to 4"(2.54-10.16cm). It is installed into the mainline of the irrigation system, near the point
  • Installing FCT Tee
    The Flow-Sync Sensor is designed to install within an FCT tee fitting, sized for the pipe in which it will be installed. For international applications, optional slip-BSP
  • Installing HFS Sensor
    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
  • Wiring
    WARNING! Flow-Sync is only designed for low-voltage connection to approved irrigation controller flow terminals. do not install in high-voltage 110V or 230V circuits. Flow-Sync
  • Specifications
    Operating Specifications Temperature Pressures Humidity 0 to 140ºF/60ºC up to 200 psi/13.7 bar up to 100%
  • System Status Indicator
    The Flow-Clik Interface Box has a System Status indicator LED that provides information on the current status of the Flow-Clik system.   RED indicates an unacceptable
  • Wiring
      Wiring the Sensor to the Interface Box   The red and black leads from the Flow-Clik sensor are connected to the red and black leads on the Interface Box. A minimum
  • Programming the Interface Box
    Using the Flow-Clik Interface Box, the sensor is calibrated by pressing the Calibrate button while the highest flow zone is operating.  While the system is learning the flow, the
  • Setting Startup Delay
    The high velocities that are common during initial activation of an irrigation cycle could cause the Flow-Clik to sense a “high flow” situation (primarily due to air trapped within
  • Setting Interrupt Period
    The Flow-Clik monitors for a high flow condition, shutting down the system or individual zone when overflow occurs. Once the system has been shut off due to a high flow condition,

  • Compatible Controllers
  • Winterization
    Flow sensors can potentially be damaged by winterization blow-out techniques, and should be removed prior to injecting compressed air into the pipes. Hunter Flow Sync
