進(jìn)口渦街流量計(jì)

進(jìn)口渦街流量計(jì)                

●結(jié)構(gòu)簡(jiǎn)單而牢固，無(wú)可動(dòng)部件，提供可靠*運(yùn)行                                                    

●安裝簡(jiǎn)單，維護(hù)十分方便                                                                                          

●檢測(cè)傳感器不直接接觸被測(cè)介質(zhì)，性能穩(wěn)定，壽命長(zhǎng)                                                

●輸出是與流量成正比的脈沖信號(hào)，無(wú)零點(diǎn)漂移，精度高                                             

●測(cè)量范圍寬，量程比可達(dá)1:10～1:30                                                                          

●壓力損失較小，運(yùn)行費(fèi)用低，節(jié)能減排                                                                     

●應(yīng)用范圍廣，蒸汽、氣體、油基液體、水基液體的流量均可測(cè)量          

原理，結(jié)構(gòu)                                                                       

在流體中設(shè)置非流線(xiàn)型旋渦發(fā)生體（阻流體），則從旋渦發(fā)生體兩側(cè)交替地產(chǎn)生兩列有規(guī)則的旋渦，這種旋渦稱(chēng)為卡曼渦街，通過(guò)測(cè)量卡門(mén)渦街分離頻率便可算出瞬時(shí)流量和累計(jì)流量

特點(diǎn)                                                                     

"其不受介質(zhì)溫度、壓力、粘度及組分的影響，同時(shí)不堵、不卡、不易結(jié)垢、耐高溫、高壓，適用于惡劣環(huán)境。流量計(jì)分一體化顯示和遠(yuǎn)傳顯示，并可輸出脈沖信號(hào)或電流信號(hào)與微機(jī)聯(lián)網(wǎng)。

應(yīng)用                                                                                   

應(yīng)用于各領(lǐng)域 蒸汽、氣體、液體的流量瞬時(shí)流量和累計(jì)流量測(cè)量
