Water Flow Tracking
Precision ultrasonic water measurement.
Online Out of the Box
No wires, gateway or WiFi. Scan the QR code, set your alarms and consumption limits in about a minute, and the meter reports on its own over its built-in eSIM.
Leak Detection & Alarms
A leak-detection algorithm reads the hourly consumption data and raises an alarm when water keeps flowing: the slow trickle a mechanical meter misses.
Built for Fluid Management
Commercial Buildings
Read every suite, tenant line or main remotely and rank them by consumption. No site visits and no gateway.
Irrigation & Agriculture
Ensure accurate crop watering and track system efficiency without manual readings.
