Due to its high stability,liquid piston pressure gauges are often used as standard devices for value trans-mission and traceability.However,in practical use,most of them are not equipped with corresponding level instru-ments,or the accuracy of the level instruments cannot meet the requirements of use.Therefore,this article designs two sets of experiments to discuss and analyze the changes in inclination and verticality caused by their calibration and use on the effective area and output pressure of the piston,and proposes production and use suggestions.
