style="text-indent:25px">電磁流量計以無壓損、高精度、價格適中等優(yōu)勢，廣受石化、化工等行業(yè)企業(yè)的青睞，在流量計量中擔任著重要的角色。然而在實際應用中，受操作不當、設備選擇不合理、安裝不科學的情況，測量誤差就很難避免，給使用者造成麻煩?？偟膩碚f，造成電磁流量計誤差的主要影響因素可以分為三類：選型不當，待測液影響和干擾。造成電磁流量計誤差的主要影響因素，選型不當：1、混合相流體測量：用電磁流量計測量液固混合相流體(如含泥沙的水)的流量時，如果選用由單相液體校準的電磁流量計，嘉興高精度流量計銷售廠家，則會產(chǎn)生測量誤差，此時應選擇不會引起液固相分離的直管段處安裝傳感器。2，嘉興高精度流量計銷售廠家，嘉興高精度流量計銷售廠家、電極及襯里材料選擇：電極及襯里材料直接與待測液體接觸，應根據(jù)待測液體的特性(如腐蝕性、磨蝕性等)及工作溫度選擇電極及襯里材料，如選擇不當，則會造成附著速度快、腐蝕、結垢、磨損、襯里變形等問題，進而產(chǎn)生測量誤差。電磁流量計使用中的常見故障，有的是由于儀表本身元器件損壞引起的故障。嘉興高精度流量計銷售廠家</p><div

style="text-indent:25px">如何避免電磁流量計中氣泡噪聲：1、應從安裝上滿足電磁流量計上游直管段長度要求,規(guī)范儀表的安裝,選擇遠離熱源的安裝場所,合理使用管道流動速,選用光潔度高的PFA氟塑料襯里和高純氧化鋁工業(yè)陶瓷導管。這些措施將有助于防止或減小旋渦和氣體分離的發(fā)生。也就是說,改進傳感器制造工藝、改善使用儀表環(huán)境條件和安裝條件、采用儀表上游加裝排氣閥等措施,有可能避免問題的發(fā)生。2、合理地設置流量計阻尼時間和功能,也可以解決出現(xiàn)氣泡噪聲測量的誤報警。阻尼時間的選擇是根據(jù)流量信號中發(fā)生氣泡噪聲的脈沖寬度來選取。一般應取阻尼時間為氣泡噪聲脈沖寬度的3~5倍。如氣泡噪聲脈沖寬度是10s,阻尼時間應取30~50s。具體選擇應根據(jù)要求的控制精度,3倍脈沖寬度控制誤差在5%,5倍脈沖寬度控制精度高于1%。嘉興高精度流量計銷售廠家低壓損流體――道爾管流量計、文丘里流量計、彎管流量計。</p><div

style="text-indent:25px">電磁流量計想要計量準必須避開幾個環(huán)境至關重要：電磁流量計安裝應該根據(jù)要求去做，首先就是對環(huán)境的要求，大家要引起重視。1、地電位變化：地電位變化會影響流量測量，例如其他設備接地線上產(chǎn)生電壓降，可使電磁流量計地電位變化，若形成較大共模干擾時，可會影響測量2、潮氣浸入：電磁流量計應用于給排水工業(yè)常將流量傳感器在低于地平線的儀表井中，因而時常會浸在未及時排放的雨水中，甚至長期浸泡在水中。即使是外殼保護等級為IP67（塵密短時浸水級）或IP68（塵密連續(xù)浸水級），也會因接線端子盒蓋密封墊圈或電纜引入密封套圈未壓緊密封，漏裝套圈，或套圈與電纜外徑未匹配，經(jīng)常發(fā)生這類事故。</p><p style="text-indent:25px">電磁流量計磁場邊緣效應對測量有什么影響：在電磁流量計電極上能測兩感應電動勢與無限長磁場下的感應電動勢大小是不一樣的，會產(chǎn)生有誤差現(xiàn)象，如果流量計管壁是導電的，因為導電管壁的短路作用，磁場邊緣效果就會更加的明顯?，F(xiàn)在隨著管壁導電率與壁厚的變化，影響也是會更加的明顯，從而會導致電極上感應電動勢的損失增加。對電磁流量計來說測量管壁絕緣是非常重要的，所以在管壁通常是要涂上絕緣層，若是被測介質中是含有導磁性物質，磁場邊緣效果就會更加的復雜。因為導磁物質的存在，會使電磁流量計磁場發(fā)生有嚴重的硬性，造成了測量的非線性，在測量液體中含有液態(tài)金屬，一般都是采用直流勵磁來減少磁場邊緣的效果。電池供電型電磁流量計目前所使用的不是很多，主要是用在現(xiàn)場沒有任何電源的情況下來使用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="嘉興高精度流量計銷售廠家,流量計" src="https://tyunfile.71360.com/UploadFile/nanyishiye/637400142383325195/522346.png"></div><p style="text-indent:25px">電磁流量計液體方面（如液體電導率均勻性,電極污染等問題）的原因：液體電導率變化或不均勻,在靜止時會使零點變動,流動時使輸出晃動。因此流量計位置應遠離注入藥液點或管道化學反應段下游,流量傳感器裝在這些場所的上游。液體若含有固相,或雜質沉積測量管內壁，或在測量管內壁結垢，或電極被油脂等污穢等等,均有可能出現(xiàn)零點變動。因為內壁表面結垢和和電極污穢程度不可能完全一樣和對稱，破壞廠初始凋零設定的平衡狀況.積極措施足除去污穢和沉積垢層;若零伙變動不大也可嘗試重新調零。檢查電極接觸電阻和電極絕緣電阻分2步進行：（1）充滿液體測量電極表面勺液體接觸電阻流量傳感器卸下信號電纜接線,用萬用表分別測量每電極與接地點,間的電阻,兩電極對地電姐值之左應在10％－20％.第九節(jié)中"一/電極接觸電阻的測量"將有進一步說明。（2）空管測量電極絕緣放空測量管,用干布揩于內表面,待完全干燥后,用H500VDC兆歐表測量各電極與地間的電阻們,阻值必須在100MΩ以上。電磁流量計的量程范圍極寬，其測量范圍度可達100：1，有的甚至達1000：1的可運行流量范圍。嘉興高精度流量計銷售廠家</p><p

style="text-indent:25px">電磁流量計電極四氟襯里加工工藝方法：電磁流量計測量中，電解質流動體對金屬電極的電化學反應會產(chǎn)生直流動極化電壓。這種與流動速無關的電壓被稱為流動體噪聲。流動體噪聲一直是電磁流量計要解決的重要技術問題之一,從1832年法拉第*次應用地磁場和電磁感應方法測量泰晤士河流動速，到現(xiàn)在人們普遍地應用電磁流量計測量導電液體流量，電磁流量計的流動體噪聲問題一直是一個困擾。尤其在進入低頻矩形波勵磁時代以來，流動體噪聲的影響表現(xiàn)得更為突出。往往有些新裝配的流量計受電極極化的影響，輸出擺動需要經(jīng)過長時間在水中浸泡才能消除。流動體噪聲的較大小直接影響到流量計測量的靈敏度、線性度和穩(wěn)定性，因此如何深入研究流動體噪聲，探尋其產(chǎn)生的原因，找到降低流動體噪聲的方法，提高傳感器信噪比，特別是對微弱勵磁電流動（電磁水表、兩線制電磁流量計）的發(fā)展和低流動速（0.1m/s以較）及高流動速（15m/s以上）流量測量范圍的擴展具有重較大意義。嘉興高精度流量計銷售廠家</p></p><br
