摘要
介绍了气体超声流量计的工作原理、干标方法在气体超声流量计标定中的可行性和使用气体超声流量计干标技术的各个步骤及应遵循的几点要求。
The operation principle of gas ultrasonic flowmeter, the importance of dry-measurement method in gas ultra-sonic flowmeter calibration and application procedures as well as the requirement to be met for dry-measurement method are introduced. It is pointed out that the uncertainty of this method itself will producein practical use.
