為了智能電磁流量計(jì)能夠很好地正常使用，智能電磁流量計(jì)傳感器接地一定要安裝好。智能電磁流量計(jì)傳感器接地時，應(yīng)注意以下幾點(diǎn)： </p> <p> 1、傳感器、轉(zhuǎn)換器的接地在現(xiàn)場，去二次儀表的屏蔽層在控制室一側(cè)接地，切勿多端接地，南京長頸噴嘴流量計(jì)哪家比較好，以免因電位不同而引入干擾。 </p> <p> 2、傳感器安裝在金屬管道上，可將傳感器的接地導(dǎo)線按制造廠的要求連接在管道法蘭上，形成可靠的接地回路儀表的接地點(diǎn)應(yīng)是一個**的接地點(diǎn)，不可以共用其他電氣設(shè)備的接地。 </p> <p> 3、傳感器的測量管、外殼、屏蔽線、轉(zhuǎn)換器及二次儀表都要接地。 </p> <p>

差壓式流量計(jì)是一類應(yīng)用的流量計(jì),在各類流量儀表中其使用量占居**。近年來,由于各種新型流量計(jì)的問世,它的使用量百分?jǐn)?shù)逐漸下降,但目前仍是重要的一類流量計(jì)。 </p> <p> 優(yōu)點(diǎn): </p> <p> (1)應(yīng)用多的孔板式流量計(jì)結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長; </p> <p> (2)應(yīng)用范圍,至今尚無任何一類流量計(jì)可與之相比擬; </p> <p> (3)檢測件與變送器、顯示儀表分別由不同廠家生產(chǎn),便于規(guī)模經(jīng)濟(jì)生產(chǎn)。 </p> <p> 缺點(diǎn): </p> <p> (1)測量精度普遍偏低;<span style="display:none;"></span> </p> <p> (2)范圍度窄,一般* 3:1~4:1; </p> <p> (3)現(xiàn)場安裝條件要求高; </p> <p> (4)壓損大(指孔板、噴嘴等)。無錫液體渦輪流量計(jì)廠家直供電磁流量計(jì)的常規(guī)直管段要求是**D后5D，在有彎管、閥門的情況分別有不同的要求。</p><div style="width:100%;text-align: center;"><img

測量流體流量的儀表統(tǒng)稱為流量計(jì)或流量表．流量計(jì)是工業(yè)測量中重要的儀表之一．隨著工業(yè)生產(chǎn)的發(fā)展，對流量測量的準(zhǔn)確度和范圍的要求越來越高，流量測量技術(shù)日新月異．為了適應(yīng)各種用途，各種類型的流量計(jì)相繼問世。目前已投入使用的流量計(jì)已超過 100 種。 </p> <p> 每種產(chǎn)品都有它特定的適用性,也都有它的局限性。按測量原理分有力學(xué)原理、熱學(xué)原理、聲學(xué)原理、電學(xué)原理、光學(xué)原理、原子物理學(xué)原理等。 </p> <p> 檢測件又可按其標(biāo)準(zhǔn)化程度分為二大類:標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。 </p> <p> 所謂標(biāo)準(zhǔn)檢測件是只要按照標(biāo)準(zhǔn)文件設(shè)計(jì)、制造、安裝和使用,無須經(jīng)實(shí)流標(biāo)定即可確定其流量值和估算測量誤差。 </p> <p> <span style="font-size:12px;">非標(biāo)準(zhǔn)檢測件是成熟程度較差的,尚未列入國際標(biāo)準(zhǔn)中的檢測件。</span> </p><p> 電磁流量計(jì) </p> <p> 工作原理：基于法拉第電磁感應(yīng)定律。在電磁流量計(jì)中，測量管內(nèi)的導(dǎo)電介質(zhì)相當(dāng)于法拉第試驗(yàn)中的導(dǎo)電金屬桿，上下兩端的兩個電磁線圈產(chǎn)生恒定磁常當(dāng)有導(dǎo)電介質(zhì)流過時，則會產(chǎn)生感應(yīng)電壓。管道內(nèi)部的兩個電極測量產(chǎn)生的感應(yīng)電壓。測量管道通過不導(dǎo)電的內(nèi)襯(橡膠，特氟隆等)實(shí)現(xiàn)與流體和測量電極的電磁隔離。 </p> <p> 工作特點(diǎn)：①具有雙向測量系統(tǒng);② 傳感器所需的直管段較短，長度為5倍的管道直徑；③ 壓力損失??；④測量不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響；⑤主要應(yīng)用于污水處理方面。孔板流量計(jì)標(biāo)準(zhǔn)型節(jié)流裝置無須實(shí)流校準(zhǔn)，即可投用。</p><div
