摘要
通过实验研究了转子式流速仪轴线与流速方向有夹角(偏流角)时,其测量速度预报值与真值之间的误差,以及流速仪用于近水面测量时水面对测量精度的影响.
The paper discusses experimtally the current velocity divergence of the output valuefrom the real one when the axial direction of rotor current meter is not in accordance with thecurrent direction,and the influence on the measure precision when a rotor current meter isused to measure current velocity near by free surface. Some valuable conclusions are obtainedwhich can be referred to in practice.
