style="text-indent:25px">超聲波液位計(jì)頂部藍(lán)色故障燈的解決辦法：超聲波液位計(jì)常見故障的問題就是頂部藍(lán)色故障燈。結(jié)合實(shí)際列出了以下解決方法：在超聲波持續(xù)零液位時(shí)，頂部燈亮，輸出電流是22MA。而且隔一段時(shí)間以后恢復(fù)液位時(shí)，故障就不能自動(dòng)解除，需要關(guān)電重啟后正常，這給客戶帶來不必要的麻煩甚至損失（例如晚上無人值守的時(shí)候）。解決的辦法就是選用非金屬支架。因?yàn)檫x用非金屬支架后，螺紋處的發(fā)射波能穿透出去，而零點(diǎn)液位的回波信號(hào)會(huì)大于螺紋處的回波信號(hào)。經(jīng)過上述解釋與實(shí)際改進(jìn)后，故障全部解決，供需雙方皆大歡喜。從而進(jìn)一步加強(qiáng)了合作。出現(xiàn)這種故障就是安裝附件的選擇問題，超聲波的發(fā)射除了平面頭以外，在螺紋這里也是有發(fā)射的。如果持續(xù)的零位，在加上安裝件選用金屬支架。超聲波液位計(jì)就會(huì)識(shí)別到支架部分的信號(hào)強(qiáng)度大于平面頭接收的信號(hào)強(qiáng)度。而金屬支架部分與發(fā)射波之間處于盲區(qū)距離。所以超聲波處于保護(hù)狀態(tài)，故障燈常亮，輸出22MA。</p><p

style="text-indent:25px">浮筒液位計(jì)的分類:浮筒液位計(jì)按照浮筒所裝位置的不同也分為內(nèi)浮筒和外浮筒兩種類型，所謂內(nèi)外的劃分是指浮筒安裝的場(chǎng)所，在被測(cè)液體的容器中就是內(nèi)浮筒，在被測(cè)液體容器之外就叫外浮筒。內(nèi)浮筒液位計(jì)本身不帶測(cè)量筒，浮筒直接安裝在盛有液體的容器中，其主要應(yīng)用于零位罐、地下池等低于地面的環(huán)境。內(nèi)浮筒液位計(jì)通過頂部法蘭垂直安裝在這些容器的頂部。外浮筒液位計(jì)本身帶有測(cè)量筒，測(cè)量筒上下通過接口法蘭與被測(cè)液體的容器側(cè)面相連，形成一個(gè)等液位的連通器，浮筒通過頂部的扭力桿和連接鋼絲懸掛在測(cè)量筒中心。液位計(jì)正確選型才能保證液位計(jì)更好的使用。寧波液位計(jì)哪家便宜</p><p
