New-type Ultrasonic Flow meter design based on FPGA High-speed Data Sampling

摘要：

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 80MHz and sample depth is 1K byte,it can fulfill the requirement of ultrasonic flow meter software arithmetic to sampling. The design can upgrade on-line. Thus,systems whole performance is improved.

关键词： data sampling FPGA flow meter.
