摘　　要：标校装置对保证计量仪表的准确性具有重要作用。通过实验测试,对比威力巴流量计在环形风洞、音速喷嘴、压力环道3种流量标校装置中的误差,结果表明,威力巴流量计适合采用音速喷嘴和压力环道进行校准,可为威力巴流量计标校装置的选择提供参考。Calibration devices play an important role in ensuring the accuracy of measuring instruments.Through experimental testing,the error of Wilbur flowmeter in three flow calibration devices:annular wind tunnel,sonic nozzle,and pressure loop was compared.The results showed that Wilbur flowmeter was suitable for calibration using sonic nozzle and pressure loop,which could provide a reference for the selection of calibration devices for Wilbur flowmeter.
