Discover the new ADDRA ultrasonic water meter — an innovative solution for accurate and reliable residential water metering. The meter is easy to install, highly accurate, and designed for long-term operation. With no moving parts, ADDRA requires no maintenance and maintains measurement accuracy throughout its entire service life without the need for recalibration.
A key feature of the new ADDRA version is its compatibility with a shut-off valve, enabling prepaid functionality based on the international STS standard. The valve is purchased separately and communicates with the meter via the BLE interface and NFC
The meter includes a replaceable external powerbank, which significantly extends the device’s operational life. If necessary, the battery can be easily replaced — ensuring convenience and long-term reliability.
Thanks to its ultra-low starting flow of just 1 liter per hour, ADDRA detects even the smallest consumption. All usage data is automatically recorded and securely stored in the device memory.
The user-friendly LCD displays total water consumption, alerts on possible leaks, reverse flow, and other important events.
The meter offers a wide range of interfaces: local access via smartphone, tablet, or computer, valve connection, and remote data transmission through various communication channels. This makes ADDRA a cost-effective and flexible solution for modern water metering — compliant with international quality and safety standards.
