摘　　要：文章主要研究方向为石油化工气态物料介质中未知声速值,在超声波流量计设置菜单中没有对应测试介质菜单,探索出获取物料声速的方法,并利用现有超声波流量计的功能进行声速修正,确定准确声速,从而测量现场气态物料介质的流量。The main research direction of this article is the unknown sound velocity value in the petrochemical gaseous material medium.There is no corresponding testing medium menu in the ultrasonic flow meter setting menu,and a method to obtain the sound velocity of the material is explored.The function of the existing ultrasonic flow meter is used to correct the sound velocity,determine the accurate sound velocity,and measure the flow rate of the on-site gaseous material medium.

关 键 词：声速 传播时间法 流速 超声波流量计 传感器
