Different methods of calculating the orifice conductance's correction factor, an important factor for the determining the pressure in dynamic calibration system, have been compared in this paper. This value has been calculated for conductance system recently applied in Instituto di Metrologia Gustavo Colonetti (Italy). Comparison of analytical methods with Monte-Carlo simulations shows that the last method could be successfully use for metrological purposes with uncertainties of the order of 10-5.
