孔板流量計(jì)安裝前基本要求：1．孔板流量計(jì)安裝前應(yīng)仔細(xì)核對(duì)標(biāo)準(zhǔn)孔板的編號(hào)、位號(hào)、規(guī)格是否與管道情況、流量范圍等參數(shù)相符。在取壓口附近標(biāo)有“+”的一端應(yīng)與流體上游管段聯(lián)接，標(biāo)有“—”的一端應(yīng)與流體下游管段聯(lián)接。2．對(duì)于新設(shè)管路系統(tǒng)，必須先經(jīng)掃線后再安裝標(biāo)準(zhǔn)孔板，以防管內(nèi)雜物堵塞或損傷標(biāo)準(zhǔn)孔板。3．標(biāo)準(zhǔn)孔板的中心線應(yīng)當(dāng)與管道中心線同軸?？装辶髁坑?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)可以通過測(cè)量壓差來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。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px"> 智能電磁流量計(jì)傳感器接地很重要，尤其在管道存在雜散電流干擾時(shí)，只有良好的接地保護(hù)，才能使智能電磁流量計(jì)準(zhǔn)確地測(cè)量。也許在沒有這種干擾的環(huán)境里，不接地并不影響流量計(jì)準(zhǔn)確測(cè)量，但是一旦環(huán)境改變，即造成流量計(jì)不能準(zhǔn)確穩(wěn)定地工作，所以我們?cè)诎惭b時(shí)比較好做好傳感器接地保護(hù)，給智能電磁流量計(jì)創(chuàng)造一個(gè)良好的工作環(huán)境。接地環(huán)分為普通型和保護(hù)型，一般是使用普通型，若被測(cè)介質(zhì)是磨損性的，宜使用帶頸的保護(hù)接地環(huán)。以保護(hù)進(jìn)口端的襯里，延長(zhǎng)使用壽命。若口徑在200mm以下的智能電磁流量計(jì)，選用聚四氟乙烯襯里時(shí)，應(yīng)選用接地環(huán)，以保證在管道連接安裝時(shí)保護(hù)襯里不受損壞，接地環(huán)通常是不銹鋼或Hc合金的。電磁流量計(jì)不產(chǎn)生流量檢測(cè)所造成的壓力損失,節(jié)能效果好;</p><div

style="text-indent:25px">電磁流量計(jì)接地的原因：電磁流量計(jì)內(nèi)的測(cè)量電極處于一個(gè)直流或交流電場(chǎng)內(nèi)，如果其環(huán)境不能有效地被屏蔽于一個(gè)無干擾的條件下，對(duì)測(cè)量有嚴(yán)重干擾。傳感器外殼接地與否，直接關(guān)系到測(cè)量的精度和穩(wěn)定性，接地導(dǎo)線必須不傳任何干擾電壓，因此電磁流量計(jì)要求有非常可靠的接地，要做好接地屏蔽，否則就會(huì)產(chǎn)生干擾電流。電磁流量計(jì)接地的好處：若連接流量計(jì)的管道是(相對(duì)于被測(cè)介質(zhì))絕緣的則要用接地環(huán)，它的材質(zhì)應(yīng)根據(jù)被測(cè)介質(zhì)的腐蝕性選用。如果是聚四氟乙烯內(nèi)襯的測(cè)量傳感器，為了保測(cè)量傳感器能正常工作，要選用接地環(huán)。超聲波流量計(jì)質(zhì)量流量計(jì)額安裝時(shí)建議在流量計(jì)進(jìn)口處加過濾器。河南電磁流量計(jì)價(jià)格</p><p

熱式質(zhì)量流量計(jì)（恒溫差TMF）優(yōu)點(diǎn):（1）球閥安裝，安裝拆卸方便。并可以帶壓安裝。（2）基于金氏定律，直接測(cè)量質(zhì)量流量。測(cè)量值不受壓力和溫度影響。（3）響應(yīng)迅速。（4）量程范圍大，管道式安裝小可以測(cè)量8.8mm管道的流量，比較大可以測(cè)到30’’（5）插入式類型的流量計(jì)，一支流量計(jì)可以用于測(cè)量多種管徑。缺點(diǎn):（1）精度不及其他類型流量計(jì)，一般為3％。（2）適用范圍窄，只能用于測(cè)量干燥的非**性的氣體，如壓縮空氣、氮?dú)?、氬氣及其他中性氣體。
