The Flow-Clik™ system includes the HFS (Hunter Flow-Sync®) as well as the Flow-Clik interface module. This system is designed to be used with controllers that do not have the capability to process flow information built in. The Flow-Clik will work on any controller's normally closed sensor circuit, or on any 24VAC controller by interrupting the common circuit. For example the Flow-Clik can be used on the Hunter X-Core, Pro-C and ICC. In an overflow condition, it will respond by activating the sensor circuit on the base controller, stopping the controller from irrigating.
The Hunter Flow-Sync (HFS) is the sensor used with flow monitoring commercial controllers, such as I-Core, ACC, and ACC2. These controllers have the ability to process the flow internally, thus there is no need for the Flow-Clik Module. These controllers can manage flow by station; record flow totals, and respond individually by station. The same sensor is used in the Flow-Clik package and is available as a separate part (part # HFS). The FCT (Flow-Clik Tee) is ordered separately based on the mainline size.
