Smart Water Meter LPWAN Radiomodule

  • Request for the price

    IoT module designed for easy integration with most of the traditional water meters enabling remote readings monitoring with NB-Fi long-range wide-area network. Radiomodule integration is the cost-effective option for water management utilities willing to remote read their water meters with minimum investments in a wide area.

    Custom modifications are available


Radiomodule scans the readings from water meter counter using an optical sensor, process them and transmits data via WAVIoT wireless network. Radiomodule can be integrated with various types of water meters.  Integration process can be performed by WAVIoT engineers or by customers team with WAVIoT support.

Smart water meter LPWAN radiomodule is long-range RF module designed to become an easily integrated upgrade for most of the existing water meters manufactured all over the world. Minor changes in the original meter’s body frame and radiomodule components layout may still be required depending on the exact model.

Key benefits

  • Integration with most types of residential water meters
  • Enable long-range scalable AMI system for smart water metering
  • Over-the-web data monitoring, readings aggregation in IoT Cloud
  • Antenna specially designed for best performance within iron water pipes and hard-to-reach places
  • Long-range signal transmission: 10+ km in urban and 30+ km in rural area
  • Readings via optical sensor; more robust than seal switch
  • Programmable frequency of reading transmission; 1-2 times per day by default
  • Hourly consumption statistic register
  • Nonvolatile memory for 1080 hourly / 60 daily / 48 monthly readings

Cost efficiency considerations

WAVIoT is well positioned as a provider of turn-key solutions to for its clients. The general idea behind it is as simple as it gets – a client needs end-user devices and turn-key solutions available of the shelve ready to work in any part of the world.

Though water metering standards and traditional hardware suppliers may differ a lot from location to location. At the moment WAVIoT is focused on the international expansion and deployment of large scale LPWAN solutions around the globe, in this context cooperation with recognizable local manufacturers is of high priority for us.

  • LPWAN Smart Water Meter Radiomodule
  • We aim at a win-win cooperation: on the one hand, it provides a new cutting-edge LPWAN unit to the product portfolio of a proven manufacturer with well-established sales channels, on the other speeds up integration and expansion in the local market significantly.

    The hardware cost of the Smart Water Meter LPWAN Radiomodule may reach as little as practically possible. Our implementation and use case experience fairly proves that a client or end-user does not care about the technology, protocols, and other complex questions. The client needs usability and best price available in the market for a complete solution. Especially when we talk about smart meters, no one would be willing to pay any given dollar more for these kinds of devices.
