锥型流量计

FVC系列

原理，结构                                                                              

基于密封管道中的能量守恒定理，锥形流量计由于具有**的设计结构。锥形流量计是在管道中心处悬挂一锥形节流件，锥形件阻碍介质的流动，重塑流速曲线,在锥形性的下游可立即形成低压区，管道上游的正压同经节流件节流后的下游的负压之间有一差压,将正、负压用取压口取出，正压口位于管道的上游，负压口位于锥体的末端，通过测量两者之间差压,根据伯努力方程即可计算出管道中的流量，锥*于管线中心，可对所测介质的流速曲线进行优化,因此测量精度高，对仪表上、下游的直管段要求低             

特点                                                                                   

安装时无直管段要求，自清洗功能，适用于容易结垢的脏污介质，气液两项测量。      

应用                                                                                   

可测量气体、蒸汽、液体的流量，广泛应用于石油、化工、冶金、电力、供热、供水等领域的过程控制和测量
