Precautions for on-site calibration of external clamp ultrasonic flow meters
Flow measurement is an important component of metrology science,with a wide range of types and applications,playing an important role in energy conservation and emission reduction,trade settle-ment,economic fields,national defense,and other fields.In real life,many flow meters installed on pipelines do not have the conditions to be sent to the laboratory for calibration due to various reasons,and can only be calibrated online.This article combines the working principle of ultrasonic flow meters,ana-lyzes and summarizes the precautions for on-site calibration of flow meters installed in pipe sections using external clamp ultrasonic flow meters as standard meters,as well as various factors that affect measure-ment results during the measurement process,and proposes corresponding improvement methods.
