[0002] The shortcomings of existing metal pressure-bearing devices in terms of pressure measurement accuracy are mainly reflected in measurement errors and calibration issues. Measurement errors include instrument accuracy, reading errors, and data processing errors, which can reduce the reliability of measurement results.
