Hunter HC100FLOW 1-Inch Irrigation Flow Meter

The Hunter HC100FLOW is a 1-inch irrigation flow meter designed to work with Hydrawise-enabled Hunter controllers. It reports system water use through the controller and can support flow alerts, so it suits irrigation setups where remote monitoring matters, but it depends on a compatible controller and Hydrawise software.

Water-use tracking and flow-rate reporting can help monitor irrigation without visiting the site.
