ActiveMeasurement of liquid flow in closed conduits—Volumetric method
封闭管道中液体流量的测量 容积法
Application Summary AI generated
This standard specifies the volumetric method for measuring liquid flow in closed conduits, detailing procedures for using calibrated volumetric tanks or provers to determine flow rate by collecting liquid over a measured time interval. It is applied in industrial settings such as water supply, petroleum, chemical processing, and hydraulic testing facilities where accurate flow measurement is required for billing, process control, or calibration of other flow meters. The standard ensures traceability to national metrology standards and is used by testing laboratories and quality assurance departments for verification and validation of liquid flow measurement systems.
