Research on the expanded application of portable multi-channel ultrasonic flow meter
The main research direction of this article is the unknown sound velocity value in the petro-chemical 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 ve-locity,and measure the flow rate of the on-site gaseous material medium.
