Hunter Sensors

Sensor Product Category Overview

Hunter's sensing devices are designed to prevent water waste and enhance irrigation system efficiency. They offer reliability and are backed by a 5-year warranty.

Weather Sensors

Hunter Weather Sensor Devices are the simplest and most effective way to prevent irrigation system operation during inclement weather (rain, wind, freezing temperatures). They temporarily shut off sprinklers based on specific settings and automatically allow resumption without altering controller settings. Built to withstand harsh conditions.

Flow Sensors

Hunter Flow Sensors continuously monitor water flow. If a flow rate exceeds a user-predetermined amount, the device alerts the controller to shut down the affected valve. This helps prevent water waste and damage from issues like ruptured mainlines, broken lateral lines, or damaged sprinklers, thereby reducing liability exposure.

Rain Sensors

Rain Sensor Product Comparison

Rain-Clik™ / Wireless Rain-Clik™

The most advanced and versatile rain sensor, featuring a Quick Response™ mechanism that instantly shuts off the irrigation system upon rainfall. The Wireless version offers the convenience of no control wires, allowing installation up to 300 feet from the controller.

Product Features and Benefits:

• Quick Response: Shuts down the system immediately upon rain detection, preventing public perception issues and water waste.
• Adjustable Dry-Out Period: Allows users to set the time it takes for the sensor to dry out (from 2 hours to 3 days) based on local conditions, ensuring proper system reactivation.
• Durable Construction: Built with high-impact thermoplastic for longevity in various weather conditions.
• Maintenance-Free: Patented sensing mechanism requires no cleaning or maintenance.
• Includes 25' Wire: Fast and easy installation with pre-attached wire.

Installation and Maintenance:

Mounting options include standard and gutter mounts. Wiring is straightforward, connecting to controller sensor terminals or common wires. No special maintenance is required.

Troubleshooting:

Common issues include the system not coming on (check discs, wiring) or not shutting off (check wiring, bypass settings, obstructions).

Mini-Clik® Rain Sensor

A simple, accurate, and reliable rain sensor that acts as a switch to break the irrigation system circuit when it rains. It automatically compensates for rainfall and dries out to allow normal operation.

Product Features and Benefits:

• Easy Installation: Works with most irrigation controllers, available in "normally closed" and "normally open" versions.
• Durable Construction: High-impact thermoplastic withstands extreme weather.
• Maintenance-Free: No collection cups mean no debris or cleaning required.
• Adjustable Rainfall Quantities: Can be set to actuate at various rainfall amounts (1/8" to 1").
• 5-Year Warranty: Backed by Hunter Industries.

Installation Instructions:

Mounting options include standard, conduit (for Mini-Clik-C), and high-voltage (for Mini-Clik-HV). Wiring connects to controller sensor terminals or common wires. Specific instructions are provided for various controller types (SRC, ICC, Pro-C, EC) and wiring configurations.

Troubleshooting & FAQs:

Addresses issues like the system not coming on or not shutting off, and common questions about adjusting dry-out times and water savings.

Wind Sensor

Wind-Clik® Wind Sensor

This sensor acts as a switch to break the irrigation system circuit during high winds, preventing operation. It resets when wind speeds drop.

Product Features and Benefits:

• Simple Installation: Connects to "normally closed" or "normally open" controller terminals.
• Adjustable Shutoff: Shuts down the system for wind speeds between 12 and 35 mph.
• Automatic Reset: Resets at wind speeds between 8 and 24 mph.
• Damping Feature: Prevents erratic cycling due to short wind gusts.
• Liability Reduction: Prevents hazards from wind-blown water on walkways and roadways.
• Fountain Use: Can be used to prevent overspray from fountains.
• 5-Year Warranty: Hunter Industries product warranty.

Freeze Sensor

Freeze-Clik® Freeze Sensor

Controls irrigation system operation during freezing temperatures. It stops water flow when temperatures approach freezing (below 37°F/3°C) and resets when temperatures rise above this point.

Product Features and Benefits:

• Accurate Shutoff: Prevents icing on walkways and roadways by stopping water flow near freezing.
• Liability Reduction: Eliminates hazards from frozen water.
• Simple Installation: Connects to controller sensor terminals or common wires.
• 24 Volt Models: Available in standard and reverse switching models.
• Includes 25' Wire: Facilitates easy installation.
• 5-Year Warranty: Hunter Industries product warranty.

Weather Station

Mini-Weather Station

A combined unit featuring rain, wind, and optional freeze sensors in one convenient package. Ideal for commercial and municipal sites, it saves water and money.

Product Features and Benefits:

• Three Sensors in One: Combines rain, wind, and freeze sensing capabilities.
• Easy Installation: Requires only two wires to connect to the controller.
• Two Models: MWS (wind & rain) and MWS-FR (wind, rain & freeze).
• Heavy Duty Construction: Built with durable PVC for long-lasting operation.
• Rain Shutoff: Adjustable from 1/8" to 1" rainfall.
• Wind Shutoff: Adjustable from 12 to 35 mph winds.
• Freeze Shutoff: Activates below 37°F (3°C).
• 5-Year Warranty: Hunter Industries product warranty.

Weather Sensor Options:

Includes a Sensor Bypass Switch Box (Model: BPSW) for easy manual override of sensors during servicing or troubleshooting.

Flow Sensors

Flow-Clik™ Flow Sensor

An affordable, rugged, and reliable flow monitoring system that shuts down irrigation during excess flow conditions. It helps conserve water, prevent erosion, reduce liability, and minimize repair costs.

Product Features and Benefits:

• Low Cost: Fits any budget, offering benefits of flow monitoring at a fraction of the cost of other systems.
• Liability Reduction: Minimizes litigation risk from unforeseen system breaks or sprinkler damage.
• Water Conservation: Automatic high-flow shutoff saves water and money.
• Erosion Prevention: Prevents major landscape damage from ruptured pipes or sprinkler breaks.
• Reduced Repair Costs: Minimizes damage from leaks or breaks.
• System Compatibility: Works with Hunter controllers and many other brands via an interface panel.
• Adjustable Settings: Programmable start-up delay (20-300 seconds) and interrupt period (5-60 minutes).
• Customized Calibration: Allows precise system control by learning flow rates.
• Wide Range: Available for pipe diameters from 1" to 4", measuring flow from 6 GPM to 400 GPM.
• Long Distance Installation: Can be installed up to 1000 ft from the controller with appropriate wiring.
• 5-Year Warranty: Hunter Industries product warranty.
