Question 1

Is the 1" flow meter the most common size?

Accepted Answer

Yes. The 1-inch HC-100-FLOW is the most popular choice because the majority of residential irrigation mainlines in the US are 1-inch pipe. Check your mainline pipe size before ordering.

Question 2

How does leak detection work?

Accepted Answer

The flow sensor learns the expected flow rate for each zone over time. When the actual flow deviates significantly from the baseline — indicating a leak, broken head, or stuck valve — Hydrawise sends an alert and can automatically shut off the system.

Question 3

Can I use this with the wireless flow add-on?

Accepted Answer

Yes. If running a sensor wire is impractical, you can pair any HC flow meter with the W-HC-FLOW wireless add-on kit, which transmits flow data wirelessly to the controller.
