标准摘要
[中文适用范围]： 本文件描述了建立和运行超声波（传输时间）测流站，用于连续测量河流、明渠或封闭管道中的流量。它还描述了该方法所基于的基本原理、相关仪器的运行和性能以及调试程序。本文件仅限于超声波脉冲的“传输时间”技术，不适用于利用“多普勒频移”、“相关”或“水位-流量”技术的系统。本文件不适用于有冰的河流中的测量。 [外文原描述]： ISO 6416 describes the establishment and operation of an ultrasonic (transit-time) gauging station for the continuous measurement of discharge in a river, an open channel or a closed conduit. It also describes the basic principles on which the method is based, the operation and performance of associated instrumentation and procedures for commissioning. It is limited to the "transit time of ultrasonic pulses" technique, and is not applicable to systems that make use of the "Doppler shift" or "correlation" or "level-to-flow" techniques. ISO 6416 is not applicable to measurement in rivers with ice. NOTE ISO 6416 focuses on open channel flow measurement. IEC 60041 covers the use of the technique for full pipe flow measurement.
英文名称Hydrometry — Measurement of discharge by the ultrasonic transit time (time of flight) method
