摘要
在石油工业生产中,流量测试十分重要。超声波的频率随流速变化而发生变化,流速与流量是联系在一起的,通过测量超声波的频率差可以测量出气体的流量。采用超声波频差法在低流速的情况下对气体流量进行测试,测试结果表明用超声波频差法测气体流量具有较高的测试精度。
In petroleum industry,it is very important to test the gas flux. The frequency of ultrasonic is different on different velocity. The gas flux is related to the velocity. In this thesis,the gas flux was tested under low velocity with the frequency difference method of ultrasonic. The result illuminated that the frequency difference method of ultrasonic has good precision when the gas flux was tested.
