ADDRA functions

Automation of data collection. This makes the process easier, more efficient and cheaper.

Possibility to control the water supply valve. In the event of an emergency, leakage or non-payment, it is possible to partially or completely shut off the water supply remotely.

Receive information about emergency situations via notifications.

Monitoring of water consumption 24/7.

Optimization and minimization of water losses.

This metering and data transmission system is based on modern ultrasonic technology. The reliability of the system has been proven by the experience of its use in many parts of the world.

Data transmission in this system is realized by LoRaWan technology, as well as between closely located devices via Bluetooth. Further data management is integrated with special top-level software SIMS, which allows collecting all the data from one municipality in one system, such as gas, heat, and electricity consumption. During the time the program has been in use, it has proven to be reliable, simple, and flexible.


Simple and easy to install. No additional equipment is required. All commissioning is carried out remotely on the server.


This system has already been tested in a variety of conditions, geographies and needs.


Reliable billing, encrypted information, and constant service support make the system reliable and secure.


Communication between the meter and the server is carried out via LoRa wireless communication.

It is interesting and symbolic that one of the first large-scale ADDRA implementation projects took place in Segovia (Spain), home to the longest surviving Roman aqueduct in Western Europe. It is 728 meters long and 28 meters high. This aqueduct is a UNESCO World Heritage Site.
