Hunter Flow-Clik Flow Sensor Kit
A ruptured pipe or broken sprinkler left undetected can result in substantial damage. Plants and ground cover can be flooded, slopes can be eroded, and hundreds of gallons of water can be wasted. Hunter created the Flow-Clik flow sensor to guard against these damages in the event of a rupture. The Flow-Clik can be programmed at a specified level of flow. It will shut down irrigation if it detects a flow rate higher than the programmed limit. Therefore, the amount of water loss and system damage is substantially reduced in the event of high external leakage.
Features and Benefits
- Automatically shuts down system if an overflow condition occurs
- Protects against flood damage and erosion
- Calibration for exact system control: Single button allows each system to be programmed at a specified flow level
- Works with all Hunter and most non-Hunter controllers
- Multi-color LED provides system status to display when power is applied, and indicate if flow is within limits
- Compatible with most commercial and residential piping systems: Large flow range provides complete flexibility
- Warranty period: 5 years
- Flow-Clik Interface Panel: 36" leads provided for easy wiring to controller (2 wires to controller, 24 VAC terminals and 2 wires to sensor)
- Current draw: 24 VAC, 0.025 A
- Switching current: 2 A maximum
- Max. distance between interface panel and sensor: 1000 ft. (18AWG minimum wire size); 2 wires required for Flow-Clik sensor.
- Sensor Wiring: 2 x direct burial, 18 AWG or greater, color-coded or marked forpolarity, up to 1000' from controller
- Programmable start up delay: 0 to 300 seconds
- Programmable interrupt period: 2 to 60 minutes
- System status indicator light
- One button system calibration to set highest flow zone
How Flow-Clik Works: An Example
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.

How Flow-Clik Works: An Example- Cont.
Lateral Line Break:
If a break should occur on zone #3, the Flow-Clik would sense a “high flow” condition ( greater than 21 GPM) and would shut down the system for the prescribed interrupt period.
The Flow-Clik would identify a “high flow” condition approximately 20 seconds after the first valve is activated based on the irrigation schedule and the master valve would shut down.
