Common Problems and Countermeasures of Vortex Flowmeter in Steam Measurement
Vortex flowmeters are widely used in steam measurement, but in practice, issues such as steam state changes, vibration interference, and improper installation often lead to measurement errors. Based on industry technical principles and standards, this article systematically analyzes typical problems including Reynolds number limitations, two-phase flow effects, vibration interference, and insufficient temperature/pressure compensation, and proposes corresponding countermeasures such as proper selection, correct installation, enhanced maintenance, and digital signal processing to improve measurement accuracy and stability.
