From the manufacturer
The Hydrawise Compatible HC Flow Meter
When used with a Hydrawise enabled irrigation controller, the HC Flow Meter reduces the threat of damage from broken pipes or spray heads, as well as faulty wiring or valves. A healthy, beautiful landscape needs just the right amount of water to thrive. Hydrawise automatically adjusts irrigation based on highly accurate data sourced from the most advanced, internet-connected local weather stations. Advanced Predictive Watering technology looks at the forecast and previous history to fine-tune irrigation according to site needs. The controller also sends instant alerts for needed maintenance. Save water, save money, and protect your outdoor living space with Hydrawise today!
Smart irrigation means peace of mind
In addition to Hydrawise benefits such as automatic watering adjustments for hot weather, heavy rainfall, and low temperatures, the HC Flow Meter lets you keep tabs on your irrigation system remotely without on-site inspection.
Get instant alerts of potential problems
Hydrawise notifies you if it detects abnormal water flows when no zone is currently running (e.g., due to a broken pipe or faulty valve). You can also configure alerts when the water usage for an active irrigation zone changes by more than 10% (e.g., if a spray head gets broken or wiring damage occurs).
Set your own water-use limits
Online reporting and alerts are key features of Hydrawise software. View water usage for each watering cycle or check the flow rate of your system at any time.
