Abstract

The existing membrane gas meter has the disadvantages of low measurement accuracy and difficult to realize remote monitoring. The new ultrasonic gas meter can solve these problems after adopting the new Lora communication technology. This paper describes the measurement principle of the ultrasonic gas meter and the components of the ultrasonic gas meter. The hardware composition block diagram of the gas meter and the design idea of low power consumption are described. The software design framework and main design flow chart of the gas meter are described. The detailed design of segment code liquid crystal is described. The design of Lora communication module is also described in detail. The flow measurement accuracy of the gas meter in the flow range of 0.16 m³ / H ~ 6 m³ / h and the temperature adaptive flow measurement accuracy in the temperature range of - 10 °C ~ + 40 °C meet the measurement accuracy requirements of national standards, In the actual application scenario, the communication distance and communication performance of the gas meter also meet the requirements of customers. In the actual application scenario, the communication distance and communication performance of the gas meter also meet the requirements of customers. The gas meter has been used in many gas companies for a long time and in large quantities, and the results meet the use requirements. Finally, the conclusion is given and it is pointed out that the gas has reached our expected goal.
