Numerical simulation study of the 3D turbulence flow field of metal tube rotameter with special structure fixed on the level piping is carried out by the design method for flow sensor based on the computational fluid dynamics.The model of simulation is established by GAMBIT software,the flow field is simulated with FLUNT software,and the computational precision is controlled through force balance in the process of simula- tion.Comparison of results between simulation and experiment shows that,when the error absolute value of floater' force balance is 2.01%,the error absolute value of flow rate is 0.70%,which verifies the accuracy of simulation results.Furthermore,the simulating flow field of metal tube rotameter is used to optimize the flow sensor structure,and the problem of horizontal metal tube rotameter that the floater vibrates in high speed is solved.
