ISO 6416描述了用于连续测量河流、明渠或封闭管道流量的超声波(传输时间)测量站的建立和运行。它还描述了该方法所依据的基本原理、相关仪表的操作和性能以及调试程序。
它仅限于“超声波脉冲的传输时间”技术,不适用于使用“多普勒频移”或“相关”或“水平-流量”技术的系统。
ISO 6416不适用于结冰河流的测量。
注:ISO 6416侧重于明渠流量测量。
IEC 60041涵盖了全管道流量测量技术的使用。
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.
