“If we had only relied on our water bills, the high water use from the open valve could've gone on for months. But because AlertAQ™ alerted us to the problem right away,  we avoided a huge increase in water costs."

Frequently Asked Questions

How is Flowie-O installed?

Flowie-O can be installed without tools in a matter of seconds on existing commercial water meters, single or compound, indoors or outdoors.

How does Flowie-O work?

Flowie-O detects water flowing through the water meter at a minute-by-minute resolution. Flowie-O then sends this information to the Sensor Relay communication hub which, in turn, sends it to the AlertAQ™ water intelligence platform for analysis. When water use patterns deviate from normal, as determined by proprietary algorithms and user-defined thresholds, alerts are sent to registered users' phones.

Yes, Flowie-O is designed for commercial, institutional, and industrial buildings and is compatible with most water meters.
