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(wú)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?？煽康慕拥?，要做好接地屏蔽，否則就會(huì)產(chǎn)生干擾電流。<span style="font-size:12px;"> </span> </p> <p> 電磁流量計(jì)接地的好處： </p> <p> 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)。 </p> <p> 超聲波流量計(jì) </p><p> 渦街流量計(jì) </p> <p>

</p> <p> 工作特點(diǎn)：①結(jié)構(gòu)簡(jiǎn)單而牢固，無(wú)可動(dòng)部件，可靠性高，長(zhǎng)期運(yùn)行十分可靠;②安裝簡(jiǎn)單，維護(hù)十分方便;③檢測(cè)傳感器不直接接觸被測(cè)介質(zhì)，性能穩(wěn)定，壽命長(zhǎng);④輸出是與流量成正比的脈沖信號(hào)，無(wú)零點(diǎn)漂移，精度高;⑤測(cè)量范圍寬，量程比可達(dá)1：10;⑥壓力損失較小，運(yùn)行費(fèi)用低，更具節(jié)能意義。流量計(jì)有齒輪式流量計(jì)、刮板式流量計(jì)、旋轉(zhuǎn)活塞式流量計(jì)，是通過(guò)測(cè)量一個(gè)個(gè)標(biāo)準(zhǔn)體積的小容積來(lái)反映流量;</p><div

質(zhì)量流量計(jì)安裝要求1、安裝位置的選擇應(yīng)避免電磁干擾。傳感器、變送器的安裝位置以及電纜鋪設(shè)應(yīng)盡量遠(yuǎn)離易產(chǎn)生強(qiáng)電磁場(chǎng)的設(shè)備，如大功率馬達(dá)、變壓器設(shè)施、變頻設(shè)備等。2、質(zhì)量流量傳感器安裝應(yīng)使傳感器流向標(biāo)識(shí)與流體流向一致。并使箭頭指向與變送器內(nèi)部組態(tài)的流量方向一致。(注：質(zhì)量流量計(jì)可以雙向使用。如果安裝方向與實(shí)際流向相反，修改變送器內(nèi)的流向組態(tài)即可。)3、質(zhì)量流量計(jì)是根據(jù)測(cè)量管振動(dòng)原理測(cè)量的流量?jī)x表，因此傳感器安裝時(shí)應(yīng)考慮在兩側(cè)的工藝管道近法蘭處(約2～10倍管徑處)做堅(jiān)固的支撐，避免儀表及相關(guān)管路產(chǎn)生震動(dòng)。若強(qiáng)烈的管道振動(dòng)不可避免時(shí)，建議用柔性管將管道系統(tǒng)與儀表傳感器隔離。4、因質(zhì)量流量計(jì)是依據(jù)科氏力原理工作的，為避免重力對(duì)計(jì)量精度的影響。質(zhì)量流量計(jì)的測(cè)量管無(wú)論是向上還是向下安裝，都要盡量使測(cè)量管與地平面保持垂直或水平。5、安裝時(shí)連接法蘭面應(yīng)相互平行，應(yīng)使兩個(gè)法蘭的中心位于同一軸線避免產(chǎn)生附加應(yīng)力。嚴(yán)禁用傳感器硬行拉直上、下游工藝管道，否則將影響測(cè)量甚至損壞傳感器。6、在傳感器的上、下游管道上，建議安裝截止閥及旁路以方便調(diào)零、日常維護(hù)及確保傳感器在不工作時(shí)亦可處于滿管狀態(tài)。電磁流量計(jì)是根據(jù)法拉弟電磁感應(yīng)定律制成的一種測(cè)量導(dǎo)電性液體的儀表。揚(yáng)州電磁流量計(jì)銷售廠家</p><p
