Ultrasonic water meter ADDRA received LoRaWan® certification

The ADDRA Ultrasonic Water Meter (WMP15, WMP20, WMP25) is officially #LoRaWANCertified, which provides utilities and end-users the assurance that our product will be easy to deploy and work as expected.

The LoRaWAN® specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.

The main advantages of LoRaWan® technology, which ADD Grup uses to ensure communication with its water meter, are high-quality two-way communication and long distance. Two-way communication turns the ADDRA water meter from a simple resource meter into a smart control device and the range of use provides additional opportunities for better project deployment.

Receiving the #LoRaWANCertified certificate of compliance once again proves the fact that ADDRA water meters demonstrate a high degree of interoperability with any other devices and software in the field of smart water metering.

How to ensure communication with a water meter without access to power grid?

Unlike electricity meters, which are constantly connected to the power grid, water meters produced by ADD Grup are battery-powered. At the same time, they perform all the same functions: they take flow readings, send this data to the utilities, and also, thanks to the shut off valve, are able to limit the flow of water. We note that the manufacturer of smart water meters guarantees uninterrupted operation of the device on battery power for 16 years.

This fact (no access to the power grid) adds certain requirements when choosing specific communication solutions aimed at establishing two-way communication between the water meter and the resource supplier. Here we need communications that will ensure continuous communication (once every 3-4 hours), but at the same time show low battery consumption.

In this case, ADD Grup uses the world-famous LoRaWAN solution – long-range two-way communication technology – to communicate with the ADDRA meter.

Note that LoRaWAN satisfies the needs of utilities not only for data collection, but also for managing the metering infrastructure, which includes disconnecting/connecting or limiting the supply of water to the consumer for various reasons (non-payment, overconsumption, leakage or pipe break).

The ADDRA ultrasonic water meter is built on a platform that supports multiple communication technologies. LoRaWAN long-distance technology is offered as the primary communication option.

In specific cases where a LoRaWAN network is not available or has insufficient coverage in some areas, this technology can be combined with short-range technology such as Wireless M-Bus for drive-by or walk-by reading technologies or BLE for smartphone communication or laptop.
