The APT-OMS-NA-6 device is intended for reading residential water meters and wireless data transmission. The transmission is carried out using Wireless M-Bus in accordance with the standard PN-EN 13757 and Open Metering System Volume 3. The open communication protocol enables compatibility with a wide range of devices forming a structure for remote readings and data transmissions. The device is built on a microprocessor system and the optical sensors used allow, among other things, optical reading of data with the water meter, recognition of the direction of water flow, reading The radio is fully compatible with the data of the water meter. The device is resistant to a strong external magnetic field and the battery source enables continuous operation for up to 12 years. The data encryption method is implemented using the AES - CBC 128-bit encryption key algorithm, which provides protection against unauthorized access to the measurement data and ensures the integrity of the data transmitted to the system.
