1、流量計(jì)有節(jié)流式流量計(jì)、畢托管流量計(jì)、均速管流量計(jì)、轉(zhuǎn)子流量計(jì)、靶式流量計(jì)，這些流量計(jì)是利用伯努利方程原理，通過(guò)測(cè)量流體差壓信號(hào)反映流量; </p> <p> 2、流量計(jì)有渦輪流量計(jì)、渦街流量計(jì)、電磁流量計(jì)、多普勒超聲波流量計(jì)、熱線測(cè)速流量計(jì)，這些是通過(guò)測(cè)量流體流速來(lái)反映流量; </p> <p> 3、流量計(jì)有齒輪式流量計(jì)、刮板式流量計(jì)、旋轉(zhuǎn)活塞式流量計(jì)，這些是通過(guò)測(cè)量一個(gè)個(gè)標(biāo)準(zhǔn)體積的小容積來(lái)反映流量; </p> <p>

5、流量計(jì)有堰槽式流量計(jì)，它是通過(guò)測(cè)量液位來(lái)反映流量。淮安電磁流量計(jì)廠家電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問(wèn)題,如臟污流、腐蝕流的測(cè)量。</p><div style="width:100%;text-align: center;"><img

孔板流量計(jì)使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差，介質(zhì)流動(dòng)的流量越大，在節(jié)流件前后產(chǎn)生的壓差就越大，所以孔板流量計(jì)可以通過(guò)測(cè)量壓差來(lái)衡量流體流量的大小。這種測(cè)量方法是以能量守衡定律和流動(dòng)連續(xù)性定律為基準(zhǔn)的。<span style="font-size:12px;">孔板流量計(jì)可測(cè)量管道中各種流體的流量，可測(cè)量的介質(zhì)有液體、氣體、蒸汽，被廣泛應(yīng)用于石油、化工、冶金、輕工、煤礦等工業(yè)部門。測(cè)量原理：充滿管道的流體，當(dāng)它們流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束將在節(jié)流裝置的節(jié)流件處形成局部收縮.</span> </p><p> 電磁流量計(jì) (EMF) </p> <p> 電磁流量計(jì)是根據(jù)法拉弟電磁感應(yīng)定律制成的一種測(cè)量導(dǎo)電性液體的儀表。 </p> <p> 電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問(wèn)題,如臟污流、腐蝕流的測(cè)量。 </p> <p> 70、80

(2)不產(chǎn)生流量檢測(cè)所造成的壓力損失,節(jié)能效果好; </p> <p> (3)所測(cè)得體積流量實(shí)際上不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的明顯影響; </p> <p> <span style="font-size:12px;">(4)流量范圍大,口徑范圍寬;</span> </p> <p>

(3)壓力損失較低。長(zhǎng)期使用了的智能電磁流量計(jì)的內(nèi)管里會(huì)積污垢，這樣也會(huì)影響電磁流量計(jì)的測(cè)量效果。淮安電磁流量計(jì)廠家</p><p
