| Abstract: | In this paper, virtual instrument technology and correlation theory are used to realize velocity measurement. The result and error of velocity measurement are analyzed completely. Comparing with the results of others, our testing precision is improved. It proved that the measurement technique based on pressure cross-correlation is practicable, and the virtual instrument is a strong tool in the velocity measurement. |
