PVB29-LS-20-C-11V锥流量计也有一些缺点，：需要标定、售价较高等。街流量计2.1涡街流量计特点涡街流量计主要用于工业管道介质流体的流量测量，如气体、液体、蒸气等多种介质。其特点是压力损失小，量程范围大，精度高，重复性好，在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。无可动机械零件，因此可靠性高，维护量小。仪表参数能长期稳定。涡街流量计是应用流体振荡原理来测量流量的，流体在管道中经过涡街流量变送器时，在三角柱的旋涡发生体后上下交替产生正比于流速的两列旋涡，旋涡的释放频率与流过旋涡发生体的流体平均速度及旋涡发生体特征宽度有关，可用下式表示：f=(Stv)/d式中：f―旋涡的释放频率，Hz；v―流过旋涡发生体的流体平均速度，m/s；d―旋涡发生体特征宽度，m；St―斯特罗哈数，无量纲，它的数值范围为114～127。
