摘要
水文测验中的关键参数——水流流速能否准确、及时地测量,直接影响到测验成果精度,为了提高测验精度,本文介绍了一种新型仪器——电磁流速仪,它可替代传统转子式流速仪,具有使用寿命长,不怕水中漂浮物缠绕和流冰碰撞等优点。
It directly affects the precision of hydrological survey result that velocity of water flow which is the essential parameter in the hydrological survey is accurately surveyed in time. In order to increase the survey precision,electromagnetic hydrometric current meter which is a kind of new type apparatus is introduced in this paper. The traditional rotor current meter may be substituted by the meter. It has long usefull life and extricate itself from winding by floating matter in water and from impacting by floating ice.
