BDZX一体化楔形、V锥流量计/一体化孔板（多孔）流量计BDZX Integrated Wedge-shaped, V

 BDZX系列一体化楔形、V锥流量计是集经典文丘里管及环形孔板的优点为一体的新型节流装置，它是利用锥体在流场中产生的节流效应来测量流量的，与其它节流流量计不同的是它改变了节流布局，从中心孔节流改变为环形节流，其理论原理是基于封闭管道中能量守恒定律的伯努力方程和流动连续性方程，在稳定流的情况下，管道中的流速与差压的平方根成正比，V锥流量计稳定性好，准确度高，重复性好，量程比宽，对安装管路要求低，压损小，可测量含有固体颗粒流体，高压流体，高含湿气体及各种赃污流体。公称通径：DN50~DN1800mm。
The BDZX series of integrated wedge-shaped and V-shaped flowmeters are a new type of throttling device that combines the advantages of the classic Venturi tube and the annular orifice plate. It measures flow by utilizing the throttling effect produced by the cone in the flow field. Unlike other throttling flowmeters, it changes the throttling layout, shifting from central hole throttling to annular throttling. Its theoretical principle is based on the Bernoulli equation and the continuity equation of fluid flow, which are derived from the law of conservation of energy in a closed pipeline. Under stable flow conditions, the flow velocity in the pipeline is proportional to the square root of the differential pressure. The V-shaped flowmeter has good stability, high accuracy, good repeatability, a wide range ratio, low requirements for installation piping, low pressure loss, and can measure fluids containing solid particles, high-pressure fluids, high-humidity gases, and various dirty fluids. Nominal diameter: DN50 to DN1800mm.
