代購(gòu)E+H電磁流量計(jì)@E+H流量計(jì)安裝思路

1.安裝位臵  只有當(dāng)滿管時(shí)才能獲得準(zhǔn)確的測(cè)量，要避免以下安裝位臵： 

（1）管道zui高點(diǎn)（易聚積氣泡）； 

（2）直接向下的管線的敞開出口前；  

（3）泵的入口側(cè)（防止抽壓而造成的對(duì)流量管襯里的破壞）； 

（4）有殘?jiān)鄯e的場(chǎng)合和排水管的zui低點(diǎn)（安裝一個(gè)清潔閥）。 

2.安裝方位  zui適宜的方位可幫助避免氣體的累積和測(cè)量管內(nèi)的殘?jiān)娣e。垂直安裝、流體自下而上的安裝位臵為*方位。若為水平安裝，測(cè)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(shí)間絕緣。空管檢測(cè)功能僅當(dāng)測(cè)量裝臵為水平安裝及變送器外殼向上時(shí)能正確工作。  

3.振動(dòng)  如果振動(dòng)劇烈，注意支撐管道和傳感器；若振動(dòng)非常劇烈應(yīng)將傳感器和變送器分開安裝。不允許利用外框承住傳感器的重量，這會(huì)使外框變形并破壞內(nèi)部勵(lì)磁線圈。  

4.出入口直管段  安裝傳感器時(shí)要盡量避免閥門、三通、彎頭等組件，與他們之間的距離應(yīng)能保證所需的進(jìn)口和出口直管段以確保測(cè)量精度：入口長(zhǎng)度≥5DN，出口長(zhǎng)度≥2DN。

 三、電氣連接 1. 變送器的密封  因?yàn)殡姶帕髁坑?jì)變送器腔體內(nèi)的電路板極易受到如水、潮濕氣體、腐蝕性氣體等的腐蝕而損壞，所以電纜入線口必須要加上電纜密封套，易燃易爆場(chǎng)所還要滿足相應(yīng)的防爆要求，這一點(diǎn)要特別注意。 

 ! 注：密封性不好極易造成電路板損壞！  2. 電纜敷設(shè)及接線  （1）供電電纜的導(dǎo)線截面積zui大不超過2.5mm2 ，供電電源：85…260V AC,20…55V AC,16…62V DC。端子:L1對(duì)AC,L+對(duì)DC; 端子NO.2:N對(duì)AC,L-對(duì)DC。不能接入380V交流電源。

四、操作 顯示操作面板  您可以通過就地顯示屏，直接讀到所有關(guān)于測(cè)量點(diǎn)的重要參數(shù)和設(shè)定參數(shù)。顯示區(qū)有兩行顯示，可以顯示測(cè)量值和狀態(tài)變量（流量方向，部分漏管，棒圖等）。您可以根據(jù)需要和喜愛改變參數(shù)變量的顯示行。  液晶顯示  兩行有背光的液晶顯示測(cè)量值、診斷信息、對(duì)話文字、錯(cuò)誤信息和提示信息。當(dāng)正常測(cè)量過程中，屏幕顯示主頁（操作模式）。  上顯示行：顯示主要測(cè)量值，如：用ml/min或%為單位的體積流量；  下顯示行：顯示補(bǔ)充的測(cè)量變量和狀態(tài)變量，如：以m3為單位的累加器，棒圖，測(cè)量點(diǎn)設(shè)計(jì)。  輸入按鈕E
