Abstract :
The measurement principle and hardware structure of a new-style time-difference method ultrasonic flow meter are presented. Software arithmetic based on FPGA high-speed data sampling technology is put forward. Sample speed is up to 80 MHz and sample depth is 1 K byte, it can fulfill the requirement of ultrasonic flow meter software arithmetic to sampling. The design can upgrade on-line. Thus, system´s whole performance is improved.
