ActiveMeasurement of fluid flow in closed conduits—Ultrasonic transit-time meters for liquid
封闭管道中流体流量的测量 渡越时间法液体超声流量计
Application Summary AI generated
This standard specifies the technical requirements, test methods, and performance evaluation for ultrasonic transit-time flow meters used to measure liquid flow in closed, full pipes. It is applied in industrial process control, water supply and wastewater management, and custody transfer metering where accurate, non-intrusive flow measurement of clean or slightly dirty liquids is required. The standard ensures consistency in meter calibration, installation, and verification across manufacturing and field testing contexts.
