天然气的管道输送中越来越多的使用到超声波流量计,超声波流量计在量程比、可靠性、重复性、计量准确度方面都有明显的优势,但实际工作中也会受到环境因素影响,本文从超声波流量计的工作原理出发,来讨论影响其运行准确性的因素以及保证准确运行的相干措施。 Ultrasonic flowmeters are increasingly used in pipeline transportation of natural gas. Ultrasonic flowmeters have obvious advantages in measuring range, reliability, repeatability and measurement accuracy, but they are also affected by environmental factors in practical work. From the working principle of the ultrasonic flowmeter to discuss the factors that affect the accuracy of its operation and to ensure accurate operation of the relevant measures.
