为了向山西省“气化山西”战略实施提供技术支撑,有效推进四气(天然气、煤层气、焦炉煤气、煤制气)合一工作,同时向企业提供过程检测、气体能源计量等气体流量计的量值传递与溯源服务,山西省计量院积极开展了“DN600大口径气体流量标准装置”的研制,该装置采用音速喷嘴法和标准表法兼顾的工作方式,既可满足科学研究需要的高准确度,又可满足日常检定的工作效率需要,同时具有较好的节能经济性。装置的流量范围为(1~15000)m3/h,音速喷嘴法系统不确
In order to provide technical support to the implementation of Shanxi Gasification Shanxi Strategy and effectively promote the integration of four gas (natural gas, coalbed methane, coke oven gas and coal gas) and to provide enterprises with process testing, gas energy metering, etc. Gas flowmeter value transfer and traceability services, Shanxi Province Institute of Metrology actively launched “DN600 large diameter gas flow standard device ” development, the device uses the sonic nozzle method and the standard method of table work both to meet Scientific research needs high accuracy, but also meet the daily verification of the work efficiency needs, at the same time have a better energy economy. Device flow range (1 ~ 15000) m3 / h, sonic velocity nozzle system is not accurate
