Always on. Always working.

Thanks to a standalone, cellular network connection, Flowie-O is more secure and more reliable than leading WiFi connected devices. Plus, it works even during power outages.

$28 to $41 million in potential water costs avoided in one year

Most of that waste came from silent leaks: stuck flappers, failed valves, supply line drips.The 2026 report puts a number on the risks your buildings face.

Works with existing water meters

The Flowie-O flex-strap, as well as the extension cable and pulse cable accessories allow for installation on a wide range of single or compound water meter brands and sizes.

Indoor or outdoor use

Flowie-O is IP67 waterproof rated meaning it can be installed in water meter pits, which, let's be honest, get kind of wet.

30-second installation

Designed with scalability in mind, Flowie-O can be installed fast giving building teams access to minute-by-minute water use data immediately after install.

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 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.
