Development of flow stability experimental platform on water flow calibration facility

摘要

To study the flow stability of the flow calibration facility under different pressure stabilizing methods, analyze the influencing factors, and improve it. The paper develops a flow stability experimental platform. The flow range of it is 0.04∼4 m³/h, the uncertainty of it is better than 0.05% (k=2). It proves that experimental platform works well and can reflect the difference of the flow stability under different pressure stabilizing methods according to the results of experiment on them.
