Hunter HC (Hydrawise) Flow Meters

The Hunter HC Hydrawise™ Smart Flow Meter is designed to give homeowners, contractors, and landscape professionals a smarter way to monitor and protect irrigation systems. By integrating directly with Hydrawise-enabled Wi-Fi controllers, the HC flow meter provides real-time visibility into system water usage, ensuring early detection of leaks, breaks, or abnormal flow conditions before costly damage occurs.

Available in 20, 25, 40, and 50 mm BSP brass-bodied models, the HC flow meter is simple to install and built tough with robust union fittings for easy removal during maintenance or winterisation. The on-meter analogue dial provides convenient manual readings in cubic metres, while the built-in leak detector offers instant visual feedback. Once connected to Hydrawise, the meter delivers station-level flow rates, total system water usage reports, and instant alerts for high, low, or unscheduled flows — making it an invaluable tool for both water efficiency and landscape protection.

For added versatility, the HC Flow Meter can also be upgraded with wireless communication kits, transmitting flow data up to 152 m (line of sight) without the need to dig trenches or run wires.
