How do Flowie and Flowie-O work?

Flowie & Flowie-O are able to track water flow up to the minute by passively receiving the mechanical signals sent by the water meter. All data is securely transmitted to the Alert Labs Building Insights Dashboard to be viewed by assigned users. Algorithms interpret water usage patterns to determine if a property is experiencing unusual water usage events such as leaks or floods. Flowie and Flowie-O meet FCC requirements.
