文丘利管与A+K平衡流量计的应用比较

Comparison of Applications of Venturi Tube and A+K Balanced Flow Meter

在工业生产中,差压式流量计是流量测量中应用最多的流量计,对于压力低、大管径、低流速的蒸汽测量,我们通常选用文丘利管。随着工业要求的提高,我们发现,对传统节流装置进行平衡整流得到的A+K平衡流量计具有比文丘利管更高的性价比。

In petrochemical Industry,differential pressure flow meter is the most popularly used meter.For the measurement of steam in large diameter piping with low pressure and flowing velocity,Venturi tube meter is often applied.With the improvement of industrial requirements,it has been found that A＋K balanced flow meter,which is formed from balanced rectification with traditional throttling device,has higher ratio of characteristic to cost than that of Venturi tube meter.
