Design of Intelligent Flow Totalizer Based on Dual CPU

Triggered from the actual needs of many engineering applications, an intelligent totalizer that can measure the temperature, pressure, instantaneous flow and cumulative flow of the measured gas and upload these parameters to the cloud is designed. This integrator uses dual STM32 chips, flow calculation related formula mathematical models and algorithms to complete the measurement and calculation of related parameters of the measured gas. The system hardware principle block diagram and software algorithm flow chart are given, and combined with the system The design plan describes the main functional modules; the inspection results of the relevant departments show that the totalizer has high detection accuracy, stable and reliable operation, and has been gradually applied in the market.
