标准范围

本文件规定了用于流动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。这种方法需要将仪器拖过一个直开式水箱中的静水。它包括测量仪器、校准程序、显示结果的方法以及与该方法相关的不确定度。

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.
