Advantages of balanced orifice flowmeters
2011-10-17 17:18:08

四孔 流通的方式 被称之为 平衡孔板流量计 The four - hole flow method adopted on the basis of the standard orifice plate flowmeter is called a balanced orifice plate flowmeter . 即标准流量计的全新升级版本 ,标准孔板升级的 流量计 我们的 测量带了 更多的方便快捷 ,比如以前因为 被测体 压损大而放弃用标准孔板 来测量的,现在 平衡 孔板 流量计 就在绝大程度上 避免了标准孔板在使用现场 因为 压损大 而不能实现的测量。 The balanced orifice plate flowmeter is a new upgraded version of the standard flowmeter. The upgraded orifice plate flowmeter has brought us more convenience and speed . For example, because of the large pressure loss of the measured body, we have given up using the standard orifice plate to measure Now, the balanced orifice plate flow meter has largely avoided the measurement of standard orifice plates at the application site because of the large pressure loss . 直管段前后需要长的缺点 平衡 孔板 流量计 也在 测量方面 大大 提高 标准孔板精 Because of the shortcomings of the standard orifice plate straight pipe section , the balanced orifice plate flowmeter also greatly improves the accuracy of the standard orifice plate .

孔板 流量计 标准孔板 相比有以下 优点 Balanced orifice flowmeters have the following advantages over standard orifice plates
平衡 孔板 流量计 进行对流体实际平衡 的时候 , 降低涡流和振动 0; A. When the balanced orifice plate flowmeter is actually balancing the fluid , the eddy current and vibration are reduced .

、平衡 孔板 流量计 现在的测量 范围度 正常比值大 20:1 ,而 标准孔板只有1:3 ; B. The normal ratio of the measurement range of the balanced orifice plate flowmeter is now about 20: 1 , compared with the original standard orifice plate of only 1: 3 ;

由于 它的 紊流剪切力的明显减小,大幅度降低了介质与节流件直接的摩擦,其 β 值长期保持不变,整个仪表 也就没有了 可动 部件,因此可以长期保持稳定性 C. Because its turbulent shear force is significantly reduced, the direct friction between the medium and the throttle is greatly reduced. Its β value remains unchanged for a long time, and the entire instrument has no movable parts, so it can be used for a long time. Maintain stability . 保持 标准孔板的所有测量优势,适合测量高温高压的场合,适用于测量所有现场介质的 Secondly, it also maintains all the measurement advantages of standard orifice plates, suitable for measuring high temperature and high pressure occasions, and suitable for measuring all field media . 平衡孔板 流量计长期性 以及 稳定 性比较的 好。 Therefore, the long-term stability of the balanced orifice flowmeter is better.

用户 开始 认为平衡孔板流量计和标准孔板流量计差不多 但是通过我们 以上 分析, 相信一定的会有改观的吧 Many users begin to think that the balanced orifice flowmeter is similar to the standard orifice flowmeter , but through our analysis above , I believe that it will definitely change .
