由苏联研制成功的流水速度测量用电化学转换器是由两个直接插入流水中的微电极和测量线路组成。它的工作原理是通过测量电极把流水运动速度的变化转换为电极总电阻的变化。在0～1厘米/秒的流速范围内,其统计特性近似于线性。转换器的偶然误差则根据实验数据来估计,在置信度为95％时,其估计 Developed by the Soviet Union, the speed of the water used to measure the electrochemical converter is composed of two directly inserted into the flow of microelectrodes and measurement lines. It works by measuring the electrode to change the speed of movement of water into the total resistance of the electrode changes. In the flow rate range of 0 to 1 cm / sec, its statistical properties are approximately linear. The accidental error of the converter is estimated based on the experimental data. At a confidence level of 95%, its estimate
