Design of Rotameter Based on CFD Simulation

针对小流量测量精度低等问题,文中提出了一种基于6DOF模型和浮子流量传感器工作原理的浮子流量传感器CFD仿真方法,基于该仿真方法,设计了一种流量范围为60~600 mL/h用于水流量检测的浮子流量传感器。结果显示:当传感器的关键结构参数锥管锥半角为0.1°、浮子直径为2.98 mm时,浮子流量传感器性能达到最优。通过实流实验验证了设计方案的可行性。

A CFD simulation method for rotameter based on the 6DOF model and the working principle of rotameter was proposed in this paper to address the issues of low accuracy of low flow rate measurement.Based on this simulation method,a rotameter for water flow detection with flow range of 60~600 mL/h was designed.The results show that the performance of the rotameter is optimized when the cone half angle of the cone tube is 0.1°and the float diameter is 2.98 mm.The feasibility of the design scheme is verified through actual flow experiments.
