| Abstract: | The design method of calibrating flow device based on static volumetric method is analyzed. Some key techniques, e.g. pressure stability of device, selection of changeover, and design of process vessel, are studied emphatically, and the correlative parameters of device are analyzed in detail. The scheme of device structure is proposed. Via large amounts of experimental data, the reliability of device is verified. which is significant to establish a flow standard device with high precision. |
