Abstract：In order to solve the problem of traceability of stack flowmeter, a stack flowrate standard facility was developed in National Insititute of Metrology. The facility uses a laser Doppler velocimeter which is calibrated by a spinning disk to traceable to SI unit as primary standard meter. The laser Doppler velocimeter was used to scan the flow profile and an ultrasonic flowmeter was used to correct the flow fluctuation. After calibrated by the laser Doppler velocimeter, the 8-path ultrasonic flowmeter is used as the working standard, the flow range is 908~104840m3/h, the expanded uncertainty of the facility is 0.62% (k=2), it can calibrate the flowmeter with a largest diameter of 1 meter. The test section of the facility includes circular pipelines and a rectangular pipeline, which can study the measurement performance of stack flowmeters.
