基于密封管道中的能量守恒定理，錐形流量計(jì)由于具有的設(shè)計(jì)結(jié)構(gòu)。錐形流量計(jì)是在管道中心處懸掛一錐形節(jié)流件，錐形件阻礙介質(zhì)的流動(dòng)，重塑流速曲線,在錐形性的下游可立即形成低壓區(qū)，管道上游的正壓同經(jīng)節(jié)流件節(jié)流后的下游的負(fù)壓之間有一差壓,將正、負(fù)壓用取壓口取出，正壓口位于管道的上游，負(fù)壓口位于錐體的末端，通過測(cè)量兩者之間差壓,根據(jù)伯努力方程即可計(jì)算出管道中的流量，錐體位于管線中心，可對(duì)所測(cè)介質(zhì)的流速曲線進(jìn)行優(yōu)化,因此測(cè)量高，對(duì)儀表上、下游的直管段要求低             

特點(diǎn)                                                                                   

安裝時(shí)無直管段要求，自清洗功能，適用于容易結(jié)垢的臟污介質(zhì)，氣液兩項(xiàng)測(cè)量。
