分析并验证了流量计因低压标定高压运行所产生的附加误差，通过引入压力修正系数Ｃｐ对仪表值进行定量修正，并在实际生产中取得一定的经济效益和社会效益。对误差的消除提出了相应的改进途径。
Analyzed and verified the additional error caused by the high pressure operation of the flowmeter calibrated by low pressure, through the introduction of pressure correction coefficient Cp to quantitatively correct the meter value, and achieved certain economic and social benefits in the actual production. The elimination of the error put forward corresponding improvements.
