摘　　要：为保证燃气表检验结果的一致性和准确性,需要确保多台位燃气表检验装置的一致性。通常采用性能稳定的燃气表作为比对标准对音速喷嘴式检验装置逐台进行测试,根据相关测试数据分析判断及偏差修正,控制不同装置之间的误差差值在一定范围内。试验结果表明该方法可以有效解决由台位差所导致的校准结果偏差问题,可以提高检验装置检测结果的一致性,并提升产品的检验效率和质量。In order to ensure the consistency and accuracy of inspection results of gas meter,it is necessary to ensure the consistency of multistage sonic nozzle type gas meter inspection devices.The gas meter with stable performance is usually used as standards of comparison to test the sonic nozzle devices one by one.According to the relevant test data,the error difference between different devices is controlled within a certain range.The test results show that this method can effectively solve the deviation problem of calibration results caused by the station difference,to improve the consistency of the inspection device,the inspection efficiency and product quality.
