楔型錐流量計(jì)工作原理Working principle
流體通過模形流量計(jì)時(shí),由于模塊的節(jié)流作用,在其上、下游側(cè)產(chǎn)生了一個(gè)與流量值成平方關(guān)系的差壓,將此差壓從楔塊兩側(cè)取壓口引出,送至差壓變送器轉(zhuǎn)變?yōu)殡娦盘?hào)輸出,再經(jīng)專用智能流量計(jì)算儀運(yùn)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 catculator,and the value of the flow can be acquired.

楔型錐流量計(jì)特點(diǎn)
1、一體化:集楔形流量傳感器、三閥組板和差壓變送器于一體,提高了系統(tǒng)的測量精度與可靠性。
2、節(jié)能型:楔式流量計(jì)的壓差小,通過整體保溫方式,避免了利用蒸汽或電伴熱的能源損耗,節(jié)能效果良好。
3、長期運(yùn)行精度高、穩(wěn)定性好。
4、傳感器結(jié)構(gòu)簡單可靠,無可移動(dòng)部件與易損部件,使用壽命長
5、適用范圍廣,除應(yīng)用于一般氣體、液體、蒸汽外,特別適用于高粘度、高腐蝕、易結(jié)晶、含懸浮物、長纖維的液體及高含塵氣體的流量測量。
