速度矢量分量的热线测量使用具有三个正交线的传感器，利用线灵敏度的各向异性效应。该传感器连接到三通道风速计电路和数据采集和处理系统。使用改进的测量速度矢量分量算法从测量信号中获得速度矢量分量，从而最大限度地减少本文所述的测量误差。与经典算法相比，相对误差的标准差显着减小。
Hot-wire measurements of velocity vector components use a sensor with three orthogonal wires, taking advantage of an anisotropic effect of wire sensitivity. The sensor is connected to a three-channel anemometric circuit and a data acquisition and processing system. Velocity vector components are obtained from measurement signals, using a modified algorithm for measuring velocity vector components enabling the minimization of measurement errors described in this paper. The standard deviation of the relative error was significantly reduced in comparison with the classical algorithm.
