| Abstract: | In order to remove the time difference of the traditional flow calculation methods, this paper analyzed the flow calculation of virtual vertical velocity time difference method. The results show that the virtual vertical line ultrasonic method is consistent with the traditional ultrasonic method and the current velocity meter method, and the virtual vertical line method performs better than the traditional ultrasonic method. It can provide reference for engineers and technicians and technical support for the localization of ultrasonic method flow measurement device. |
