智能型電磁流量計(jì)傳感器在工藝管道上的安裝：1.智能型電磁流量計(jì)測堵管在任何時刻必須完全注滿介質(zhì)，不能在不滿管或空管的情況下正常工作。在介質(zhì)不滿管時，可采用抬高流量計(jì)后端出水管高度的方法使介質(zhì)滿管，避免不滿管及氣體附著在電極上。2.管道內(nèi)有真空會損壞流量計(jì)的內(nèi)襯，需特別注意。3.流動的正方向應(yīng)與流量計(jì)上箭頭所指的正方向一致。4.智能型電磁流量計(jì)即可在直管道上安裝，插入式渦街流量計(jì)介紹，也可以在水平或傾斜管道上安裝，但要求二電極的中心連線處于水平狀態(tài)。5.對于液、固兩相流體，zui好采用垂直安裝，使被測介質(zhì)自上而xialiu動，可使流量計(jì)襯里磨損均勻，延長使用壽命。6.流量計(jì)在管道法蘭附近確保有足夠的空間，以便安裝和維護(hù)。7.若測量管道有振動，在流量計(jì)的兩側(cè)應(yīng)有固定的支座。8.測量介質(zhì)為重污染液體的，插入式渦街流量計(jì)介紹，在旁路管道安裝流量計(jì)本體，不中斷工藝運(yùn)行，即可排空與清流。9.安裝聚四氟乙烯內(nèi)襯的流量計(jì)時，連接法蘭的螺栓應(yīng)注意均勻擰緊，否則容易壓壞聚四氟乙烯內(nèi)襯，zui好用力矩扳手，插入式渦街流量計(jì)介紹。將浮子位移量轉(zhuǎn)換成電流或氣壓模擬量信號輸出，分別成為電遠(yuǎn)傳浮子流量計(jì)和氣遠(yuǎn)傳浮子流量計(jì)。插入式渦街流量計(jì)介紹</p><div

大部分結(jié)構(gòu)浮子流量計(jì)只能用于自下向上垂直流的管道安裝。浮子流量計(jì)可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500，雷諾數(shù)變化流量系數(shù)即保持常數(shù)，亦即流體粘度變化不影響流量系數(shù)。這數(shù)值遠(yuǎn)低于標(biāo)準(zhǔn)孔板等節(jié)流差壓式儀表比較低雷諾數(shù)104-105的要求。

使用流體和出廠標(biāo)定流體不同時，要作流量示值修正。液體用浮子流量計(jì)通常以水標(biāo)定，氣體用空氣標(biāo)定，如實(shí)際使用流體密度、粘度與之不同，流量要偏離原分度值，要作換算修正。插入式渦街流量計(jì)介紹浮子流量計(jì)可用于較低雷諾數(shù)，選用粘度不敏感形狀的浮子，流通環(huán)隙處雷諾數(shù)只要大于40或500。</p><div

style="text-indent:25px">超聲流量計(jì)是通過檢測流體流動對超聲束(或超聲脈沖)的作用以測量流量的儀表。超聲流量計(jì)主要由安裝在測量管道上的超聲換能器(或由換能器和測量管組成的超聲流量傳感器)和轉(zhuǎn)換器組成。超聲流量計(jì)和電磁流量計(jì)一樣，因儀表流通通道未設(shè)置任何阻礙件，均屬無阻礙流量計(jì)，是適于解決流量測量困難問題的一類流量計(jì)，特別在大口徑流量測量方面有較突出的優(yōu)點(diǎn)，它是發(fā)展迅速的一類流量計(jì)之一。根據(jù)對信號檢測的原理，超聲流量計(jì)可分為傳播速度差法(直接時差法、時差法、相位差法和頻差法)、波束偏移法、多普勒法、互相關(guān)法、空間濾法及噪聲法等。玻璃管浮子流量計(jì)結(jié)構(gòu)簡單，價格低廉。只要在現(xiàn)場指示流量者使用方便。插入式渦街流量計(jì)介紹</p><p

按照要求正確安裝后的橢圓齒輪流量計(jì)，使用時即可保證足夠的精度，通常累計(jì)值的精度可達(dá)0.5級，是一種較橢圓齒輪流量計(jì)為準(zhǔn)確的流量計(jì)量儀表。但是，如果使用時被測介質(zhì)的流量過小，儀表的泄漏誤差的影響就會突出，不能再保證足夠的測量精度。因此，不同型號規(guī)格的橢圓齒輪流量計(jì)對zui小使用流量有一允許值，只有當(dāng)實(shí)際被測流量大于該下限流量允許值時，測量精度才能得到保證。 </p> <p> 其次，使用橢圓齒輪流量計(jì)要注意被測介質(zhì)的溫度不能過高，否則不*會增加測量誤差，而且有使齒輪發(fā)生卡死的可能。為此，橢圓齒輪流量計(jì)在儀表所規(guī)定的使用溫度范圍內(nèi)使用。 </p> <p> 長期使用后的橢圓齒輪流量計(jì)，其內(nèi)部的齒輪會被腐蝕和磨損，從而影響測量精度。因此，要經(jīng)常注意觀察，并定期拆下進(jìn)行檢查，若條件允許要定期進(jìn)行標(biāo)定。插入式渦街流量計(jì)介紹</p><p
