| Abstract: | In an effort to explore the problem of measurement mechanism for throttling device, the formula of flow measurement was deduced on the basis of the detailed analysis of throttling phenomena. Simi- larities and differences of orifice flowmetcr, Venturi flowmeter and votameter were also compared in this study. We hope the inaccurate concepts involved in current teaching materials could be rectified so that the students could be guided to solve the correlative problems with the help of the sound understanding of flow measurement mechanism. |
