This smart ultrasonic water meter is the new flagship of the Axioma QALCO range of metering products. A new generation patented design, wide communication possibilities, IoT technology, impeccable metering accuracy and an outstanding durable housing.

This meter measures the flow of water using ultrasonic technology. The ultrasonic method is one of the most quickly-developing solutions in numerous sectors, because it can identify and immediately react to the tiniest changes in any system. Together with a high dynamic range, this ensures an exclusive flow metering accuracy and precision even with the smallest water flows. This guarantees a cost reduction of 10-20 %. The design of QALCOSONIC W1 represents a new technological evolution.

The QALCOSONIC W1 has a MID and OIML-49 certification. The communication is available via LoRaWAN® or NB-IoT®. I is completly integrated into the IQnexus IoT Platform.
