E+H電磁流量計*，正確地選用電磁流量計是保證用好電磁流量計的前提條件。選用什么種類的電磁流量計應(yīng)根據(jù)被測流體介質(zhì)的物理性質(zhì)和化學(xué)性質(zhì)來決定，使電磁流量計的通徑，流量范圍，襯里材料，電極材料和輸出電流等，都能適應(yīng)被測流體的性質(zhì)和性質(zhì)和流量的要求?？蓽y量的流體:由電磁流量計的工作原理可知，能選用電磁流量計測量流量的流體必須是導(dǎo)電的，嚴(yán)格的說，除了高溫流體之外，只要電導(dǎo)率大于5μ/cm的任何流體都選用相應(yīng)的電磁流量計來測量流量，因此不導(dǎo)電的氣體，蒸汽，油類，丙酮等物質(zhì)不能選用電磁流量計來測量流量。傳感器口徑的確定:流量計使用流速在0.3-15m/s范圍內(nèi)，此時流量計口徑可選擇與用戶管道口徑*。使用流速低于0.3m/s時在儀表部位局部提高流速，采用縮管方式：異徑管的中心錐角不大于15oC時，可把異徑管視為直管段的一部分。一體型或分離型的選擇:一體型：現(xiàn)場環(huán)境較好的情況下，一般都選用一體型，即傳感器和轉(zhuǎn)換器組裝成一體。
E+H電磁流量計*，E+H電磁流量計的優(yōu)勢及*賣點：
1.傳感器zui重要的部件－線圈作*化的設(shè)計，并通過zui嚴(yán)格的實流試驗，切實保證產(chǎn)品的測量精度
2.E+H電磁流量計的信號電極作*的靜電屏蔽處理，保證小信號不會受線圈的干擾，保證低流速的測量精度
3.E+H電磁流量計的線圈與外界作隔離處理，保證線圈長期的絕緣強度，也就保證傳感器的長期測量精度
4.傳感器所有的焊接工藝都采用氬弧焊工藝，雖然成本較高，但能保證焊接的可靠性（焊接是傳感器的zui主要的生產(chǎn)工藝），特別是安裝線圈后的zui后一道焊接工序，用氬弧焊工藝能保證已安裝的線圈不被損傷
5.E+H電磁流量計采用接地電極結(jié)構(gòu)，形成一個平衡電極平面，保證整個測量平均速度的過程都被限制在平衡電極平面之內(nèi)進(jìn)行，能很好的消除電氣噪聲干擾，提供精確的測量結(jié)果
6.采用定制的雙層屏蔽電纜
7.可編程頻率低頻矩形波勵磁，提高了流量測量的穩(wěn)定性，功率損耗低
8.特殊介質(zhì)測量（如漿液）采用高頻勵磁，消除雜波干擾
9.采用16位嵌入式微處理器，運算速度快，精度高
10.全數(shù)字處理，抗干擾能力強，測量可靠，精度高
11.超低EMI開關(guān)電源，適用電源電壓變化范圍大，抗EMC性能好
12.用單塊電路板完成所有功能設(shè)計，采用SMD器件和表面帖裝SMT）技術(shù)，電路可靠性高
13.高清晰度背光中文LCD顯示，顯示累積流量、瞬時流量、流速、流量百分比等
14.菜單操作，使用方便，操作簡單，易學(xué)易懂
15.雙向測量系統(tǒng)，內(nèi)部具有三個積算器可分別顯示正向累計量、反向累計量及差值積算量
16.E+H電磁流量計具有自檢與自診斷功能，并在屏幕上顯示
17.E+H電磁流量計采用*的防雷設(shè)計。
