NB-Fi Water Meter is designed for smart water metering solutions in flats, houses, and enterprises. NB-Fi Water Meter transmits data via NB-Fi transceiver to base stations, then base stations forward data packets to WAVIoT Meter Data Management system (MDM system) .

The electronic metering mechanism and high-quality case allow high flow measurement accuracy. The water consumption data is transmitted via NB-Fi protocol every 24 hours and contains hourly details of water consumption.

All smart NB-Fi Water Meters are supplied with a reverse flow check valve to prevent water backflow. NB-Fi Water Meters are easy to mount – coupling nuts enable installation without the use of any additional connecting elements.

NB-Fi Water Meters are equipped with magnetic field sensors that detect magnetic field impact used to fraudulently alter the readings and send an instant alert to the WAVIoT MDM system.

NB-Fi Smart Water Meter is a reliable solution for smart water metering systems. It ensures 100% collection of readings and allows getting rid of regular manual reviews. The detailed water consumption data on every user is collected in WAVIoT MDM system and may be available in a web-based interface and a mobile application. Flexible reports in different breakdowns may include the data on different consumer groups as well as totals and subtotals.

NB-Fi Water Meters can be widely used in various AMI/AMR solutions for water supply, utility management and service companies. WAVIoT MDM system can be installed in the corporate network and integrated with the existing corporate AMI / AMR / invoicing and billing system through API.
