src="https://tyunfile.71360.com/UploadFile/jszhck/637312837414560547/9988671.png"></div><p> 智能電磁流量計(jì)是60年代興起的一種流量?jī)x表，因?yàn)樗歉鶕?jù)傳統(tǒng)的物理電磁感應(yīng)原理制成的，擁有著非常獨(dú)特的特點(diǎn)，所以被的應(yīng)用到生產(chǎn)的各個(gè)領(lǐng)域，它的工作原理非常的簡(jiǎn)單，如果發(fā)生故障，維修起來也非常的方便，適合所有的工廠使用。 </p> <p> 1、連續(xù)浸水防護(hù)等級(jí)IP68型：給排水、污水處理安裝地大多為地下管線的害井內(nèi)，雨水、地下滲水常使流量計(jì)浸于水中，或冬季結(jié)露，降低接線端子和線圈的絕緣強(qiáng)度，影響產(chǎn)品性能并縮短流量計(jì)使用壽命。 </p> <p> 2、潛水型：用于明渠流量測(cè)量，替代傳統(tǒng)堪板式流量計(jì)。 </p> <p> 3、防爆型：使用于在具有可性氣體環(huán)境條件下，如化工、煤礦、油田使用。 </p> <p> 4、衛(wèi)生型：容易拆卸沖洗消毒，可快速安裝，適用于食品、醫(yī)藥部門使用。 </p> <p> 5、高壓型：對(duì)于石油化工的鉆井循環(huán)泥漿、固井水泥漿、采油工藝的高壓注水等。 </p> <p> 6、一般型：適用于除上所述的，一般的用途。 </p><p> 孔板流量計(jì)安裝對(duì)管道的要求： </p> <p> 1．孔板流量計(jì)安裝時(shí)應(yīng)配有一段測(cè)量管,至少保持**DN、后5DN的等徑直管段，以提高測(cè)量精度。 </p> <p> 2．在孔板流量計(jì)前后若需安裝閥門，比較好選閘閥且在運(yùn)行中全開；調(diào)節(jié)閥則應(yīng)在下游5DN之后的管路中。 </p> <p> 3．引壓管路的內(nèi)徑與管路長(zhǎng)度和介質(zhì)臟污程度有關(guān)，通常在45米以內(nèi)用內(nèi)徑為8-12mm的管子。 </p> <p> 4．測(cè)量液體流量時(shí)引壓管水平段應(yīng)在同一水平面內(nèi)。若是在垂直管道上安裝節(jié)流件，引壓短管之間相距一定的距離（垂線方向），這對(duì)差壓變送器的零點(diǎn)有影響，應(yīng)通過“零點(diǎn)遷移”來校正。 </p> <p> 5．引壓管路應(yīng)有牢固的支架托承，兩根取壓管路應(yīng)盡可能互相靠近并遠(yuǎn)離熱源或震動(dòng)源，測(cè)量水蒸汽流量時(shí)，應(yīng)用保溫材料一同包扎，必須時(shí)（如氣溫0℃以下）加伴熱管防止結(jié)冰。在測(cè)量臟污流量時(shí)，應(yīng)附設(shè)隔離器或沉降器。 </p> <p> 6．引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測(cè)流體是氣體時(shí)，引壓管路（包括差壓計(jì)的壓力腔）內(nèi)全部是氣相；被測(cè)流體是液體時(shí)，引壓管路內(nèi)全部是液相，不能有氣泡。為此應(yīng)在引壓管路的比較低點(diǎn)裝排水閥或在比較高點(diǎn)裝排氣閥，在新裝或檢修差壓變送器時(shí)時(shí)應(yīng)特別注意。被測(cè)流體是液體時(shí)，引壓管路內(nèi)全部是液相，不能有氣泡。</p><div
