为了能准确地对南京港华燃气有限公司内部用于“西气东输”的气体流量仪表进行检定,江苏省计量科学研究院与南京港华燃气有限公司合作建立了正压式标准表法气体流量标准装置(以下简称“装置”),开展对气体流量仪表的检定工作。一、装置的建立1.装置工作原理装置以标准流量计为主要标准器,使气体在相同时间间隔内连续通过标准流量计和被检流量计,比较两者的输出流量值,从而确定被检流量计的计量性能。装置采用正压法,且压力在(2~10)kPa可调,使被
In order to accurately test the gas flow meter for “West-East Gas Pipeline” within Nanjing Hong Kong Gas Co., Ltd., Jiangsu Institute of Metrology and Nanjing Ganghua Gas Co., Ltd. established a positive pressure standard meter Law gas flow standard device (hereinafter referred to as “device ”), carried out on the gas flow meter verification. First, the installation of devices 1. Device works Device to standard flow meter as the main standard, so that gas at the same time interval through the standard flow meter and was seized flow meter, comparing the output flow value of the two to determine the seized Metering performance of the flowmeter. Device using positive pressure method, and the pressure (2 ~ 10) kPa adjustable, so be
