The Hunter Flow-Clik Flow Sensor automatically shuts down irrigation system if an overflow condition occurs.
A ruptured pipe or broken sprinkler that is left undetected can result in a substantial amount of damage. Plants and ground cover can be flooded, a slope can be eroded, even solid surfaces such as sidewalks or driveways can be undercut. The installation of a Flow-Clik can help identify a break before any damage can occur. The Flow-Clik is user-set to activate at a specified level of flow, once that level is exceeded, the electrical circuit is broken and the valves are shut off. As a result, the amount of water loss in the event of high external leakage would be substantially reduced. Compatible with ANY 24VAC controller/timer.
At a small commercial site, the Flow-Clik sensor is connected to the mainline pipe that provides water to the system control valves. The user determines which valve has the highest flow rate and calibrates the flow sensor to automatically identify any flow in excess of this pre-determined amount, in this case, 21 gallons per minute (GPM) to be a "high flow" condition. The user also sets the desired setting for the system interrupt
and start-up delay. If flow should exceed 21 GPM, a signal would be sent to the controller to interrupt the system for a prescribed period of time.
