摘要
为防止流速仪在使用过程中因仪器转动不灵活、接触丝与信号不正常等导致所测流量不正确,常用流速仪使用50～80h后必须跟备用流速仪比测。本文以呼图壁河石门水文站比测成果为例,浅析流速仪比测方法。
In order to prevent measured flow data untrue,Because instrument invent in use is not agility,and contact silk and signal is not normal,at every turn flow speed instrument after which it is used 50-80hour must measure contrast with standby flow speed instrument.This paper takes the example of the result of measure contrast in Shimen hydrologic station of Hutubi river,brief analysis the measure contrast method of flow speed instrument.
