style="text-indent:25px">電磁流量計被擊穿的原因分析及應(yīng)對方案：在電磁流量計的應(yīng)用上，有些用戶會遇到電磁流量計轉(zhuǎn)換器電路板被燒壞的情況，尤其在夏季多雷雨的天氣，此種情況出現(xiàn)更為頻繁，結(jié)合大部分現(xiàn)場情況判斷，損壞部分為勵磁電路的電源部分，結(jié)合損壞情況判斷，是由于過壓造成勵磁電源保護穩(wěn)壓管擊穿，續(xù)電情況下進一步造成損壞器件過流產(chǎn)生高溫，促使PCB板極高溫碳化，加劇損壞情況.通?，F(xiàn)場產(chǎn)生過壓的原因有兩種情況：1、現(xiàn)場工況電源電壓不穩(wěn)，易產(chǎn)生浪涌電壓.若是建議安裝電源穩(wěn)壓器；2、雷雨季節(jié)的雷擊直接作用于電磁流量計，雷擊途徑多樣復雜，可通過一切與外部接觸的途徑，如輸入部分的電源；輸出部分的電流，頻率，通訊；流體管道傳感器的勵磁及電極.上海差壓流量計訂購螺紋連接型渦輪流量計。傳感器以螺紋方式與管道連接。</p><div

style="text-indent:25px">電磁流量計它除了有供電方式多樣性之外，它的內(nèi)在功能也是很強較大的，是能夠測量介質(zhì)的正向流量與反相流量，能夠用于測量液體介質(zhì)的流動速，是可以測量瞬時流量與累積流量。電磁流量計已經(jīng)是工業(yè)企業(yè)測量液體介質(zhì)的流量計，只要液體是有一定的導電率，就可以選擇電磁流量計作為測量的工具，它對于水、污水、硫酸等導電性液體應(yīng)用是*多的。電磁流量計如果是供電220V是可以做成一體式或是分體式，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較來使用。同時也會有故障報警的功能，正反相流量是進行切換的功能，上較流量設(shè)置并且報警功能。電磁流量計如果是供電24V就要在工業(yè)現(xiàn)場不允許使用交流動電或是從安全的方面來考慮到所采用低壓直流動電的場所，或是配有流量積算儀是有積算儀給電磁流量計進行供電的，這樣只能選擇24V供電。</p><p style="text-indent:25px">電磁流量計故障外界源頭：流體方面，液體含有均勻分布細小氣泡通常不影響正常測量，唯所測得體積流量是液體和氣體兩者之和；氣泡增大會使輸出信號波動，若氣泡大到流過電極遮蓋整個電極表面，使電極信號回路瞬時斷開，輸出信號將產(chǎn)生更**動。低頻（50／16Hz-50／6Hz）矩形波激磁電磁流量計測量液體中含有固體超過一定含量時將產(chǎn)生漿液噪聲，輸出信號亦會有一定程度波動。兩種或兩種以上液體作管道混合工藝時，若兩種液體電導率（或各自與電極間電位）有差異，在混合未均勻前即進入流量傳感器進行流量測量，輸出信號亦會產(chǎn)生波動。電極材質(zhì)與被測介質(zhì)選配不善，產(chǎn)生鈍化或氧化等化學作用，電極表面形成絕緣膜，以及電化學和極化現(xiàn)象等，均會妨礙正常測量。電磁流量計具有自檢與自論斷功能。</p><div

style="text-indent:25px">電磁流量計和超聲波流量計的主要區(qū)別，介質(zhì)不同：超聲波流量計的流量測量準確度幾乎不受被測流體溫度、壓力、粘度、密度等參數(shù)的影響，又可制成非接觸及便攜式測量儀表，故可解決其它類型儀表所難以測量的強腐蝕性、非導電性、放射性及易燃易爆介質(zhì)的流量測量問題。電磁流量計不能測量導電率很低的液體，如石油制品和有機溶劑等。通用型電磁流量計由于襯里材料限制，不能測量溫度較高液體。電磁流量計是通過測量導電液體的速度確定工作狀態(tài)下的體積流量。按照計量要求，對于液態(tài)介質(zhì)，應(yīng)測量質(zhì)量流量，測量介質(zhì)流量應(yīng)涉及到流體的密度，不同流體介質(zhì)具有不同的密度，而且隨溫度變化。如果電磁流量計轉(zhuǎn)換器不考慮流體密度，*給出常溫狀態(tài)下的體積流量是不合適的。污水流量計使用的直管段還要注意不能有負壓，以防止襯里材料脫落。紹興電磁流量計報價</p><p

style="text-indent:25px">電磁流量計適用于測量大部分電傳導液體，以及泥、漿糊和泥漿的流量。前提是被測介質(zhì)至少要有某個小電導率。溫度、壓力、粘度和密度對測量結(jié)果沒有影響。只要選擇適當?shù)墓艿酪r里材料與電極材料，也可以用來測量腐蝕性介質(zhì)。介質(zhì)中的固體顆粒不會影響測量結(jié)果。流量傳感器與智能轉(zhuǎn)換器整體地或者分離地組成一個完整的流量計。電磁流量計主要應(yīng)用在以較領(lǐng)域：1、清水、污水。2、電力生產(chǎn)和分配。3、化工和工業(yè)制藥。4、食品工業(yè)。流量的測量是應(yīng)用電磁原理在水的密閉回路中完成的，與超聲波式相比，精度更高。重要屬性如較：1、無活動部件，不存在磨損。2、流動程的測量范圍是1：100。3、無澄清段或流量加強裝置。4、應(yīng)用于測量各種導電液體的流動速。5、測量結(jié)果不受溫度、壓力、粘度和密度等物理特性影響。5、強耐腐蝕，耐磨損能力。6、可測量正向/反向流量。紹興電磁流量計報價</p><p
