style="text-indent:25px">電磁流量計磁場邊緣效應(yīng)對測量有什么影響：電磁流量計轉(zhuǎn)換器所輸入的阻抗在提高測量導(dǎo)電性液體時，一般是不會因?yàn)榻橘|(zhì)電導(dǎo)率稍有變化就會引起誤差，但是對于一定的轉(zhuǎn)換器所輸入阻抗，被測量介質(zhì)的電導(dǎo)率是有一個下限值，是不能低于該下限值的。被測介質(zhì)電導(dǎo)率太大也是不可以的，所以對一個電磁流量計來說，其測量不受到介質(zhì)電導(dǎo)率影響是有一定的范圍，被測介質(zhì)的電導(dǎo)率既不能太大，也不能太小。如果電磁流量計測量介質(zhì)的電導(dǎo)率偏高的話，磁場邊緣區(qū)就會產(chǎn)生有很大的渦電流，會引起二次磁通，會使工作磁場邊緣區(qū)兩側(cè)的磁場分別會被消弱與增強(qiáng)。所以在電磁流量計測量電導(dǎo)率介質(zhì)是不能使用交流勵磁，而使用直流激磁，在隨著電子技術(shù)持續(xù)發(fā)展，流量轉(zhuǎn)換器輸入阻抗的提高，是必可以降低被測介質(zhì)電導(dǎo)率的下限。流量計電極材質(zhì)與被測介質(zhì)配置不當(dāng)，將會有化學(xué)作用或是極化現(xiàn)象而影響到正常的測量，要根據(jù)被測介質(zhì)的腐蝕性來選擇電極的材料。可以根據(jù)被測介質(zhì)的腐蝕性、磨損性與溫度選擇電磁流量計內(nèi)襯材質(zhì)，盡量選用有防雷功能的電磁流量計。寧波液體流量計銷售我們選擇電磁流量計的襯里材料主要是根據(jù)被測介質(zhì)的腐蝕性、耐磨性、及溫度和壓力等參數(shù)。</p><div

style="text-indent:25px">電磁流量計磁場邊緣效應(yīng)對測量有什么影響：若是沿流體流動方向上的磁場始終是均勻的，在實(shí)際時，這就意味著沿著管軸方向的磁場是無限長的，而實(shí)際上電磁流量計磁場是有限長的，所以就要考慮到有限長磁場所產(chǎn)生的邊緣效果對測量的影響。如果電磁流量計管壁是絕緣的，其電極附近磁場大多都是均勻的，兩端則是會逐漸的減弱，會形成不均勻的邊緣，后就會下降至零。這樣使其液體內(nèi)部電場也會不均勻，將是會產(chǎn)生有渦電流，因?yàn)闇u電路所產(chǎn)生的二次磁通反過來會改變磁場邊緣部分的工作磁通，會使磁場的均勻性遭受到破壞。</p><p style="text-indent:25px">金屬管流量計原理是什么？金屬管轉(zhuǎn)子流量計是變面積式流量計的一種，在一根由較向上擴(kuò)展的筆直錐管中，圓形橫截面的浮子的重力是由液體動力承受的，浮子能夠在錐管內(nèi)自由地上升和較降。在流動速和浮力作用上較運(yùn)動，與浮子重量平衡后，通過磁耦合傳到與刻度盤指示流量。金屬管浮子流量計浮子在測量管中，跟著流量的改變，將浮子向上移動，在某一方位浮子所受的浮力與浮子重力到達(dá)平衡。此時浮子與孔板（或錐管）間的流動通環(huán)隙面積保持必定。環(huán)隙面積與浮子的上升高度成正比，即浮子在測量管中上升的方位替代流量的巨細(xì)。金屬錐形管浮子流量計：金屬管錐形管浮子流量計口徑15~40mm，通過磁鋼耦合等方法，將浮子的位移傳給套管外的轉(zhuǎn)換部分。與通明錐形管浮子流量計比較。可用于較高的介質(zhì)溫度和壓力，而且不易破碎。電磁流量計管道內(nèi)無可動部件，無阻流部件，測量中幾乎沒有附加壓力損失。</p><div

style="text-indent:25px">渦輪流量計有哪些獨(dú)特的優(yōu)點(diǎn)：一、高精度。我們知道，流動體的東西很難知道其它的輸出量，特別是較大型的輸出時，如果再使用稱重的方式很難達(dá)到目的，而且使用稱重的方式也不是很準(zhǔn)確，這個時候，液體渦輪流量計就表現(xiàn)出它強(qiáng)較大的優(yōu)勢，首先它在使用的時候十分的方便，只要從管道輸出的時候，就已經(jīng)知道了它的流量，它的精確度十分高，同時在使用的時候不會偏移，不會出現(xiàn)延時等現(xiàn)象。二、重復(fù)性好。對于一種東西的使用，必須要達(dá)到這一點(diǎn)，其實(shí)人們喜歡渦輪流量計，有些也正是因?yàn)檫@個原因，在對于這是進(jìn)行測量的時候，往往有些這是或者黏性較大或者是化學(xué)的腐蝕成分高，所以會對于東西產(chǎn)生一定的影響，在一次性使用之后，或者是直接的報廢，也某咱是數(shù)據(jù)不準(zhǔn)的現(xiàn)象，但是這種渦輪流量計則不同，它在設(shè)計上面使用了合理的設(shè)計，使用之后，或者隨時的清洗，隨時的把內(nèi)部的流動體介質(zhì)除去，不會影響較次的使用，而它的使用材料上面也十分的先進(jìn)，有著很強(qiáng)的抗氧化性能，一次使用之后，不會影響其性能。傳統(tǒng)電磁流量計用信號電纜易因受振動、沖擊、彎曲以及外界溫度變化，造成內(nèi)部摩擦，從而產(chǎn)生噪音。寧波液體流量計銷售</p><p

style="text-indent:25px">電磁流量計常見的錯誤安裝方式有哪些？關(guān)于安裝方位：電磁流量計的安裝方位通常分為垂直安裝和水平安裝，適宜的方位可幫助避免氣體的累積和測量管內(nèi)的殘渣存積。1、垂直安裝：這種方位對易自排空管道系統(tǒng)很理想，并可不加空管檢測電極。2、水平安裝：測量電極平面必須水平，這樣可以防止由于夾帶的氣泡而產(chǎn)生的電極短時間絕緣。注意：空管檢測功能*當(dāng)測量裝置為水平安裝及變送器外殼向上時能正確工作。如果振動非常劇烈，應(yīng)將傳感器和變送器分開安裝。3、基座，支撐：如果公稱直徑為DN≥350，在能忍受足夠負(fù)載的基座上安裝變送器。注意不允許利用外框承住傳感器的重量。這會使外框變形并破壞內(nèi)部勵磁線圈。如果可能，安裝傳感器好避免例如閥門，三通，彎頭等組件。寧波液體流量計銷售</p></p><br
