自校正双涡轮流量传感器的理论与计算

The Theory and Computation of the Self-Calibrated Dual-Turbine Flow Transducer

文中比较了几种不同形式双涡轮结构,通过对基本原理的分析、模型建立,以及理论计算,结果表明:同向旋转的双涡轮结构比其它涡轮结构具有更高的自校正精确度。文章还揭示了传统涡轮流量传感器产生测量误差的机理。

Some different kinds of dual-turbine structures are compared. By analyzing the basic principle and model establishing as well as theoretic calculation, the results show that the rotating dual turbine structure provides higher self-calib-ration accuracy than the others. The mechanism causing measuring errors in conventional flow transducers is also revealed.
