标准范围

ISO 17089的本部分规定了超声波气体流量计（USM）的要求和建议，其利用声波信号测量封闭管道中的气相流量。ISO 17089的这一部分适用于渡越时间USM，主要用于工业流量测量。包括由表体组成的仪表以及带有现场安装传感器的仪表。仪表的尺寸没有限制。它可以用于测量几乎任何类型的气体；例如但不限于空气、碳氢化合物气体和蒸汽。ISO 17089的本部分规定了USM的性能、校准（需要时）和输出特性用于气体流量测量和处理安装条件。注:国家或其他法规可能比ISO 17089本部分的规定更严格。

This part of ISO 17089 specifies requirements and recommendations for ultrasonic gas meters (USMs), whichutilize acoustic signals to measure the flow in the gaseous phase in closed conduits.This part of ISO 17089 is applicable to transit time USMs and is focused towards industrial flow measurement.Included are meters comprising meter bodies as well as meters with field-mounted transducers.There are no limits on the size of the meter. It can be applied to the measurement of almost any type of gas;such as but not limited to air, hydrocarbon gases, and steam.This part of ISO 17089 specifies performance, calibration (when required), and output characteristics of USMsfor gas flow measurement and deals with installation conditions.NOTE It is possible that national or other regulations apply which can be more stringent than those in this part of ISO 17089.
