摘要
气体标准体积管是校验各类气体流量计量仪表(包括容积式、速度式和节流装置等)的一种新型气体标准装置。应用它可实现气体流量计量仪表的现场在线实气校验。本文简述了气体体积管的原理、结构和准确度问题。气体标准体积管的准确度可优于±0.35％;介绍了在研过程中所做的性能测试和对比试验。进一步论证了气体标准体积管校表的准确性、可靠性和具有较广的应用范围。该项目获1986年石油工业部科学技术进步一等奖和1987年国家科学技术进步三等奖。
This article briefly introduces the principle, structure and accuracy of the gas prover. The accuracy of the gas prover can be higher than ±0. 35%. The article also introduces the performance test and comparing test during the course of development. The article further demonstrates the accuracy and reliability of the gas prover and its wider application- limits
