Innovative gas meter using blockchain and IoT technology enhances data integrity and security.
The design philosophy of a new smart gas meter is presented, based on an ultrasonic sensor, employing LoRa and/or NB-IoT protocols and block-chain technologies to overcome the data integrity and security issues with a completely modular design. The architecture is organized in two separate blocks, the former for measurement and the latter for communication, and it presents originality characteristics with respect to the state of the art. Accuracy of measured data is studied paying attention to fluid dynamic effects of the geometrical layout on the flow rate ultrasonic sensor and of the environmental temperature and pressure, for variable gas flowrate values. As for data security issues, the proposed solution is critically analyzed with reference to the data string organization and the procedure the data are stored and prepared for transmission into the blockchain. Finally, a local network of counters is designed and simulated in order to check the compliance of the provided hardware and software solutions with the predicted computational load.
