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. 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".
