Doppler flowmeter in the flow measurement, enterprise management and traffic monitoring and control has broad application prospects, but most still use flowmeter zero crossing detection method, the accuracy is not high. This paper theoretically introduce the use of spectrum analysis method to eliminate the theory of error, improve the measurement accuracy. At the same time introduce a hardware circuit circuits, software and test results of treatment. (2008-03-29, DOS, 183KB, 下载49次)
