转子流量计测量误差的检验和修正

Test and Correction of Erros in Flow Meassurement of Float-Type Flowmeter

在进一步分析转子流量计原理的基础上，指出了压力和温度的变化对流量测量误差的共同影响，给出了流量测量相对误差的计算。

Combined influence of the changes in the temperature and the pressure on errors in flow meassurement of the float-typeflow. meter was showed on the basis of the further analysis of its principle. The methods of calculation, test and correction of the relative error were given in this paper.
