楔形流量計是一種差壓式流量儀表,利用其內部安裝的特殊節(jié)流件,迫使管道中的流體的流動發(fā)生變化,在節(jié)流件的前后產生壓力差,從而達到測量流量的目的。
楔式流量計工作原理Working principle
流體通過模形流量計時,由于模塊的節(jié)流作用,在其上、下游側產生了一個與流量值成平方關系的差壓,將此差壓從楔塊兩側取壓口引出,送至差壓變送器轉變?yōu)殡娦盘栞敵?,再經專用智能流量計算儀運算后,即可獲知流量值。
When the fluid passes through the wedge-shape flowmeter,a differential pressure in square relationship to the value of the flow on the upstream and downstream sides due to the throttling effect of the wedge occurs.Divert the differential pressure from the pressure-tapping holes on both sides of the wedge and send it to the differential pressure transmitter to be converted into electric signals before output,which are then calculated by a special intellignet flow calculator,and the value of the flow can be acquired.
