最近,国家海洋局海洋技术研究所的科技人员在水电部黄河委员会黄河水资源保护研究所新建的大型静水槽中,对几种新研制的双旋浆流速传感器进行了线性和余弦响应特性的试验,并取得了比较好的试验结果。 试验结果表明:传感器的起动流速达到3厘米/秒;回归直线的剩余标准误差小于2厘米/秒;余弦响应与理想余弦曲线相比较,其均方根误差最小为1.04％。
Recently, the scientific and technical personnel of the State Oceanic Administration Marine Technology Institute conducted experiments on the linear and cosine response characteristics of several newly developed dual-vortex flow velocity sensors in a large new hydrostatic tank newly constructed by the Yellow River Institute of Water Resources Protection of the Yellow River Commission of the Ministry of Water Resources. , And made a good test results. The experimental results show that the starting velocity of the sensor reaches 3 cm / s, the residual standard error of the regression line is less than 2 cm / s, and the minimum square root of the cosine response is 1.04% compared with the ideal cosine curve.
