中文名称：封闭管道中流体流量的测量 夹持式渡越时间法液体和气体超声流量计
英文名称：Measurement of fluid flow in closed conduits — Clamp-on ultrasonic transit-time meters for liquids and gases
发布日期：2023-12
标准范围
This document specifies requirements and recommendations for non-intrusive (clamp-on) ultrasonic flowmeters (USMs), which use the transit time of ultrasonic signals to measure the volumetric flowrate in closed conduits. Transit time flowmeters are predominantly used on single-phase fluids (liquid and gases) but can also be used where small quantities of additional phases are present. This document specifies performance, calibration, and output characteristics, and deals with installation conditions.
