| 摘 要： | 涡街流量计的敏感元件信号强度与被测流速的二次方成正比，故测量低流速时所得信号甚小，被干扰信号所掩盖，这就是被测流速的下限．提出了对抗振动干扰和电磁干扰的方法，使量程下限得以扩展．

| Abstract: | Since the strength of signal picked up by the vortex flowmeter and velocity square is in direct ratio, the lower the velocity is, the faster the signal-strength decreases. The signal wb be blanketed by the interference signal,which is the lowest range in measuring velocity. Some methods against the interference signal, and to expend the lowest range of vortex nowmeter is put forward. |
