Sonata Ultrasonic Residential Water Meter

The Sonata is an advanced and highly accurate ultrasonic water meter and data end-point for residential applications. With no moving parts, the Sonata’s robust design ensures reliable and long lasting precision. 

Its technology enables the measurement of even the lowest of flow rates, making it the best solution for addressing NRW (Non-Revenue Water). 

The Sonata is a data rich end-point, supporting numerous protocols and is ready to meet the challenges of tomorrow’s smart water networks.

In April 2016 the Sonata won the “iF design award”.
