Rachio Wireless Flow Meter FAQ

Product Overview

The Rachio Wireless Flow Meter helps you to avoid catastrophic leaks and provides insights into your outdoor water use. The flow meter detects broken heads, ruptured pipes, and even low-flow leaks with highly-sensitive, state-of-the-art Vortex technology. It also issues notifications for leaks and blockages (and even triggers instant zone shut-off when leaks and other flow issues are detected). With Inactive Leak Detection, the Wireless Flow Meter can even check for and detect leaks when your sprinklers are not running. 

The Rachio Wireless Flow Meter uses cutting edge wireless technology to connect with the Rachio 3 Smart Sprinkler Controller. No wires means that no digging is required to connect the flow meter to the controller! Professional installation is recommended for the Wireless Flow Meter, but you may be able to install on your own (in an average of 30-60 minutes) with our DIY installation instructions.

Do you ship / sell internationally?

At this time, the Rachio Wireless Flow Meter is only available as a bundle with the Rachio 3. We do not currently ship internationally. Purchases can be made from Rachio.com.

The Wireless Flow Meter is only available for purchase and use within the United States and Canada, as the radio inside the Rachio 3 is not approved for use in countries outside the United States and Canada. Use outside of certified geographic regions could void the user’s authority to operate the equipment and will void the limited warranty.

Is the Rachio Wireless Flow Meter waterproof? Does it need an enclosure?

The Rachio Wireless Flow Meter is fully waterproof when installed correctly, so no need to worry about it getting wet!

How will I know if the flow meter is working at installation?

Once your Rachio Wireless Flow Meter is activated, the water usage chart on the home screen of your Rachio app will switch from minutes of usage to gallons or liters. If the flow meter cannot read your system’s flow rate or detect leaks, you will receive an error message. If the flow meter is not working for any reason, you will receive a notification through your email or the Rachio app.

What notifications will the Rachio Wireless Flow Meter send?

The Rachio Wireless Flow Meter will alert you anytime a high flow rate or low flow rate is recorded. You will receive notifications through email and through your Rachio app and in-app on the Home screen and within individual zones.

Do I need to winterize or freeze-proof my Rachio Wireless Flow Meter?

Nope! The revolutionary and very durable vortex technology allows the flow meter to stay in place during winterization, blowouts, and system maintenance. So no need to mess with it once it's installed!

I have a reclaimed and/or grey water sourced irrigation system with no backflow preventer. Can I still use the Wireless Flow Meter?

Definitely! Reclaimed and/or grey water sourced irrigation systems do not need backflow preventers with the Wireless Flow Meter as the source is not potable drinking water. Simply follow these instructions, and ensure there is at least six inches of straight pipe between the water source and the Wireless Flow Meter.
