摘要
超声波流量计因具有易于安装、使用方便、可进行非接触式测量等优点,在流量计量领域特别是大口径管线的计量中应用广泛。研究了液体流场变化对超声流量计测量精度的影响,并给出具体的使用建议。
The ultrasonic flowmeter is widely used in the field of flow measurement,especially the measurement of large-diameter pipelines,since it has the advantages of easy installation,convenient use,and the ability of non-contact measurement.This paper studied the impact of liquid flow field changes on the measurement accuracy of ultrasonic flowmeters and put forward specific use suggestions.
