摘　　要：分析了MQL-8201型碳平衡油耗仪所用V锥流量计的测量原理。利用仿真方法,依据V锥流量计的结构尺寸,建立了该流量计的几何模型。仿真结果表明,气体流动在到达V锥流量计前已经达到了稳定状态,压力和速度分布趋于稳定。The measuring principle of V-cone flow meter used in MQL-8201 carbon balance fuel consumption meter is analyzed.The geometric model of the V-cone flow meter was established by simulation method based on the structure size.The simulation results show that the gas flow has reached a steady state before reaching the V-cone flow meter and the pressure and velocity distribution have stabilized.
