The Flow-Know sprinkler controller is programmed with your iPhone over the Internet. The controller is compatible with all sprinkler systems that utilize 24VAC valves. Replace your old hard-to-program sprinkler controller with the simplicity and convenience of a native iPhone application.

With support for 2 flow sensors, the Flow-Know allows you to track both your household/business water usage as well as the your landscape water usage before you get surprised with a high water bill. Flow-Know provides peace of mind by reporting high, low and unexpected flows in your landscape irrigation system. 

Use a rain sensor to suspend your watering schedule and select a dry-out period to maximize your water savings.

Use any one of the 16 zones to operate as a system master valve or operate a pump relay to use water from a well or tank.

Need more than 16 zones? Add more controllers...the Flow-Know application isn't limited in the number of controllers it can manage.
