标准摘要
[中文适用范围]： 本标准规定了用于流水点速度测量的机械式、电磁式和声学式水文流量计的校准方法。 该方法需要将仪器拖过直开式水箱中的静水中。 它包括测量设备、校准程序、呈现结果的方法以及与该方法相关的不确定性。 [外文原描述]： This document specifies a calibration method for mechanical type, electromagnetic type and acoustic type hydrometric current-meters used for point velocity measurement of flowing water. The method requires towing the instrument through still water in a straight open tank. It includes measuring apparatus, the calibration procedure, the method of presenting the results and the uncertainties associated with the method.
