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(shí)，應(yīng)注意以下幾點(diǎn)： </p> <p> 1，浙江液體渦輪流量計(jì)哪家比較便宜、傳感器、轉(zhuǎn)換器的接地在現(xiàn)場(chǎng)，去二次儀表的屏蔽層在控制室一側(cè)接地，切勿多端接地，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(gè)**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(cè)量管、外殼、屏蔽線、轉(zhuǎn)換器及二次儀表都要接地。 </p> <p> 4、傳感器、轉(zhuǎn)換器應(yīng)單獨(dú)接地，浙江液體渦輪流量計(jì)哪家比較便宜，不要連在電動(dòng)機(jī)，浙江液體渦輪流量計(jì)哪家比較便宜、工藝管道上，接地電阻應(yīng)小于10歐姆。浮子流量計(jì)是僅次于差壓式流量計(jì)應(yīng)用范圍寬廣的一類(lèi)流量計(jì),特別在小、微流量方面有舉足輕重的作用。浙江液體渦輪流量計(jì)哪家比較便宜</p><div

</p> <p> <span style="font-size:12px;">差壓式流量計(jì)由一次裝置(檢測(cè)件)和二次裝置(差壓轉(zhuǎn)換和流量顯示儀表)組成。通常以檢測(cè)件形式對(duì)差壓式流量計(jì)分類(lèi),如孔板流量計(jì)、文丘里流量計(jì)、均速管流量計(jì)等。</span> </p> <p> <span

安徽金屬轉(zhuǎn)子流量計(jì)廠家渦輪流量計(jì)是速度式流量計(jì)中的主要種類(lèi),它采用多葉片的轉(zhuǎn)子)感受流體平均流速,推導(dǎo)出流量或總量的儀表。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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。 </p> <p> 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。 </p> <p> 3．標(biāo)準(zhǔn)孔板的中心線應(yīng)當(dāng)與管道中心線同軸。 </p> <p> 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。 </p><p> 水平管道基本安裝方式對(duì)于水平管道，測(cè)量氣體時(shí)推薦安裝在管道上方160度范圍內(nèi)，尤其對(duì)于有大量水粉的氣體時(shí)，我們只推薦這樣安裝;測(cè)量液體時(shí)推薦安裝在管道下方160度范圍內(nèi)，尤其對(duì)于含有大量氣體的液體時(shí)，我們只推薦這樣安裝;但有一點(diǎn)要注意，對(duì)于那些極易氣化的液體，如液態(tài)的烯烴類(lèi)介質(zhì)，安裝時(shí)插入方向同氣體，在管道上方。測(cè)量蒸汽時(shí)只推薦傳感器安裝在管道下方160度內(nèi)，并且要使傳感器處于整個(gè)測(cè)量裝置的比較高點(diǎn)。垂直管道基本安裝方式對(duì)于垂直管道，理論上可以在360度內(nèi)安裝。對(duì)于含有大量水分的濕氣體，推薦傳感器安裝時(shí)向上傾斜5度，如左圖所示。對(duì)于含有大量氣體的液體，推薦傳感器安裝時(shí)向下傾斜5度，如右圖所示。對(duì)于蒸汽，推薦傳感器安裝時(shí)下傾斜5度，如右圖，且傳感器應(yīng)該處于整個(gè)測(cè)量系統(tǒng)中的比較高點(diǎn)。威力巴安裝所需直管段小直管段要求—彎管后2D安裝如圖所示。當(dāng)管道上、下游的直管段不夠長(zhǎng)時(shí)，我們推薦在彎管后2倍管道內(nèi)徑處安裝威力巴，因在彎管后的流體剖面較復(fù)雜，需將流體系數(shù)K做適當(dāng)?shù)恼{(diào)整。調(diào)整K系數(shù)后，測(cè)量精度為±3%。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(mén)的情況分別有不同的要求。</p><div
