威力巴流量计探头以其的防堵设计,摆脱了阿牛巴等插入式流量探头易堵塞的弊端,使均速管流量探头的防堵水平达到了的高度。
当流体流过探头时,在其前部产生一个高压分布区,高压分布区的压力略高于管道的静压。根据伯努利方程原理,流体流过探头时速度加快,在探头后部产生一个低压分布区,低压分布区的压力略低于管道的静压。流体从探头流过后在探头后部产生部分真空,并在探头的两侧出现旋涡。均速流量探头的截面形状、表面粗糙状况和低压取压孔的位置是决定探头性能的关键因素。低压信号的稳定和准确对均速探头的精度和性能起决定性作用。威力巴均速流量探头能精确地检测到由流体的平均速度所产生的平均差压。威力巴均速流量探头在高、低压区有按一定准则排布的多对取压孔,使准确测平均流速成为可能.
