V錐流量計是一種差壓式流量計，工作原理同于標準節(jié)流裝置。其結構設計是流體掃過型結構，不可能截留流體中任何夾帶的氣，液、或固相污物，非常適用于臟污流體的流量測量，如焦爐煤氣、濕氣體等。尤其在測量高爐煤氣時，有自清潔作用，引壓管不易堵塞。

主要參數(shù)

產(chǎn)品特點

1.具有較寬的量程比4﹕1至10﹕1

Wide turndown ratio of 4:1 to 10:1

2.自整流功能，只需要極短的直管段（前1～3 D后2 D）

Self-rectification function, extremely short straight pipe section ((1~3)D for the front section and 2D for the rear section) required only

3.自清潔功能，可測臟污和易結垢流體，適合高爐煤氣等雜質(zhì)較多的介質(zhì)

Self-cleaning function. Allow measuring dirty and easily scaled fluids and be suitable for blast furnace gas and other media with many impurities.

4.高準確度，示值的±1%

High accuracy: within ±1% of indication

5.自保護功能，節(jié)流件關鍵部位不磨損，能保持長期穩(wěn)定地工作

Self-protection function: No wear of key parts of throttling elements, to allow long-term stable operation
