Abstract: This article utilizes MEMS sensors to obtain a large amount of data from flowmeters in gas stations, establishes a flowmeter calibration model, and combines multiple linear regression, neural networks, and other methods to fit the massive data to improve the accuracy of calibration. In addition, the installation location and installation conditions of the sensors are clarified. The results show that using MEMS sensors to obtain flowmeter data and combining with efficient modeling methods is a feasible flowmeter calibration scheme.
