|
|
Abstract This paper introduces the gas flow standard device using critical flow Venturi nozzle method,The DN600mm gas vortex flowmeter used for steam flow measurement is verified according to jjg1029-2007 《verification regulation of vortex flowmeter》,According to jjf1059.1-2012 《evaluation and expression of measurement uncertainty》, The uncertainty of the measurement result of the K coefficient at the maximum flow point (Qmax point) of the flowmeter is analyzed and evaluated,It provides reference data for the application of large-diameter vortex flowmeter in steam flow measurement.
