High-speed Data Sampling Based on FPGA and Its Application in Flowmeter

摘要：

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 80MHz and sample depth is IK byte, it can fulfill the requirement of ultrasonic flowmeter software arithmetic to sampling. The design can upgrade on-line. Thus, systems whole performance is improved.
