Measure with Accuracy
Identify Flow Problems
The Rachio Wireless Flow Meter detects leaks with highly-accurate Vortex technology and instantly alerts at the first sign of trouble. If a high-flow leak is identified, Rachio removes the affected zone from queue, continuing the rest of the watering schedule as usual.
How the Wireless Flow Meter Works.
Install the Wireless Flow Meter between your backflow preventer and valve box, then it will automatically pair with the Rachio 3 Smart Sprinkler Controller.
As you water each zone, the Wireless Flow Meter learns the baseline flow rate. If a leak is detected, Rachio will protect your landscape by sending an instant alert and shutting down only the affected zone.
Watch over your water with Vortex technology.
State-of-the-art Vortex technology measures flow rates with accuracy - down to the gallon per zone. Designed with no moving parts, this streamlined technology withstands winterization and continuous use without maintenance or repair.
Professional installation recommended.
The Rachio Wireless Flow Meter is compatible with most irrigation systems; however, pipe size and material, installation location and more can affect installation requirements. Professional installation will get you up and running in no time!
