摘要
针对传统涡街流量计在低流速测量时的不足,分析了在流速为0.29m/s和0.58m/ s时,经过数字滤波后,采集到正确信号频率的概率,最终证明了在低流速下,应用这种复合滤波的方法能够得到很好的效果。
Aiming at the fault of when vortex shedding flowmeter measures the slow velocity of flow, it analyzes mainly the probability of collection of exactitude signal after digital filter when the velocity is 0.29m/s and 0.58m/s. In the end, it improves that the filtering way may get good effect.
