基于TDC-GP2的高精度超声波流量计的设计
Design of High Precision Ultrasonic Flowmeter Based on TDC-GP2
摘要
Abstract
Based on high precision and reliability of the design idea and in view of the traditional ultrasonic flowme⁃ters the accuracy is not high and the circuit is complicated and the pipeline requires a modification. A design of flowmeter system is proposed based on FPGA and TDC-GP2 high precision time measurement chip. Using FPGA as the core of logic control module, and the principle of time difference method of ultrasonic flow meter, TDC-GP 2 was made to achieve the precise measurement of time difference,the upload data were sent through the serial port to the host computer for data processing and results display. The results show that the accuracy and reliability of the sys⁃tem meet the requirements of the system.关键词
