Development of High-Precision Wide-Range and Large-Diameter Liquid Flow Standard Device
The key technical problems of the development of high-precision,wide-range and large-diameter liquid flow standard device based on the combination of static mass method and standard table method are introduced.Through the integration of technologies such as the design of wave prevention and flow stabilization of the storage tank,the frequency conversion speed regulation and pressure stabilization of the water pump,the optimization of the structure of the pressure stabilizing tank,the monitoring of the liquid status in the tank,the optimization of the layout of the pipeline and the monitoring of the pipeline flow field,the flow field stability guarantee technology of the liquid flow standard device integrating "source-transmission-pipeline-measurement" has been formed.The reliability and accuracy of the device are improved through technologies such as reversing intelligent measurement and control,high-precision standards and automatic verification,valve leakage monitoring,and automatic data identification.
