摘要
When using time-difference principle in an ultrasonic flow-meter, the accuracy of the tested time (spending to transmit the ultrasonic in two directions) directly influences the tested precision and the tested range of the meter An ultrasonic flow-meter based on FPGA is introduced in the design. Making use of the programming characteristic and the rich inner resources and the quite high work frequency of a FPGA chip, a DS process module including a high-speed counter etc. had been designed in the chip, so that the reliability and the measure precision had been heightened. The paper emphasized on the measure principle, the configuration of the hardware system, and on the way to. heighten the precision.
