摘要
在遵循国家标准的原则下设计和制作了孔板测流系统．并用孔板测流中随机采集的试验数据分析和计算孔板测流中的系统误差和随机误差．论证所设计的孔板测流系统符合国标Ｂ级精度．
In accordance with the state specifications,a flow measurement device system using orifice plate is designed and fabricated.The experimental data analysis for flow measurement using orifice plate,and its system error and stochastic error are calculated.The results show that the designed orifice plate system for flow measurement is conformable to B level precisioin of state standards.
