Abstract :
The measurement principle and hardware structure of a new-style time-difference method ultrasonic flowmeter 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 1K byte, it can fulfill the requirement of ultrasonic flowmeter software arithmetic to sampling. The design can upgrade on-line. Thus, system´s whole performance is improved.
