Abstract :
The measurement principle and sensor structure of a new-style time-difference method ultrasonic flow meter are presented. Software waveform analyses arithmetic based on FPGA and a bran-new echo datum mark position criterion are put forward. Exact measurement time can be helpful for improving system precision. In the end, realization project is simply described.
