标准范围

本文件规定了测量？的仪器的功能要求水面（水位），主要用于确定流速。本文件由附件补充A、 它为当前可用的自动水位测量装置的类型以及与之相关的测量不确定度提供了指导。手动操作的测量装置在附录中描述B本文件适用于接触和非接触测量方法。非接触方法不与水面直接接触，而是用？测量水位高度超声波或电磁波。

This document specifies the functional requirements of instrumentation for measuring the level of water surface (stage), primarily for the purpose of determining flow rates.This document is supplemented by Annex A, which provides guidance on the types of automatic water level measurement devices currently available and the measurement uncertainty associated with them. The manually operated measuring devices are described in Annex B.This document is applicable to both contact and non-contact methods of measurement. The non-contact methods are not in direct material contact with the water surface but measure the height of the water level with ultrasonic or electromagnetic waves.
