• 臨界流

  With the gas flow calibration system based on the critical flow nozzles and positive pressure method,the experimental research has been carried out and a calculation formula has been obtained after deducing the fitting model of expansibility factor of cone flowmeters theoretically. Comparing with standard orifice,venturi,and three formulas for the cone flowmeters achieved from research organization abroad,the prediction curves and relatively error curves of the expansibility factor with different equivalent diameter ratios have been depicted.
