Development of ultra-low power natural gas metering device based on pressure sensor temperature compensation method

In the paper, the system design of the ultra-low-power intelligent gas flow metering device was described. Then the pressure sensor correction algorithm and the specific example are described in detail. Test data show the error range of the pressure measurement can be controlled within 0.3%. Based on the methods, the ultra-low power intelligent flow metering device with high precision grade was developed. Finally, the test data and the user interface figure of the device is given.
