摘要
将先进的信号处理方法和数字信号处理器 (DSP)应用于流量计的信号处理 ,计算流量信号的频率和相位差等 ,克服目前此类流量计信号处理方法的局限 ,提高测量精度和抗干扰能力 ,扩大量程比 ,实现小流量测量。研制基于DSP的涡街流量计和科里奥利质量流量计二次仪表。
To overcome the limitations of signal processing for currently-used flowmeters so as to raise their accuracy of measurement,anti-interference,and range ratio in hope of light-flow measurement,DSP-based secondary device for vortex-shedding meter and Coriolis mass flowmeter has been developed by applying advanced signal-processing method and digital signal processor(DSP)to flowmeter signal processing for the calculation of flow signal frequency and phase differential.
