style="font-size:16px;"><strong>（1）對于加油站等應用場所的地下臥式罐</strong></span> </p> <p> <span style="font-size:16px;">● 液位儀安裝位置應遠離安裝在罐內(nèi)的卸油管、潛油泵或自吸泵管路，防止流體直接沖擊；</span> </p> <p> <span style="font-size:16px;">● 安裝位置應選擇在油罐縱向的中軸線上，以減小測量死區(qū)；</span> </p> <p> <span style="font-size:16px;">● 安裝位置應選擇靠近檢尺孔，以保證相同的測量基準</span> </p> <p> <span style="font-size:16px;">● 安裝孔通徑: 應大于浮子的直徑，對加油站要求為DN100mm。</span> </p> <p> <span style="font-size:16px;"><strong>（2）對于油庫、煉化企業(yè)等應用場所的地上立式罐</strong></span> </p> <p> <span style="font-size:16px;">● 液位儀安裝位置應遠離進出油（料）口，推薦液位儀安裝位置與進出油（料）口的夾角在 45 度到135度之間,以防止流體直接沖擊浮子；</span> </p> <p> <span style="font-size:16px;">● 液位儀安裝位置距罐壁應選擇在 900mm~1200mm 范圍內(nèi)，即要避免離罐壁太近而造成的測溫不準確，又要避免因靠近罐內(nèi)由于罐底變形而對液位測量產(chǎn)生不必要的影響；</span> </p> <p> <span style="font-size:16px;">● 液位儀安裝位置同檢尺孔之間的關系。由于現(xiàn)行的實際情況是：利用手工檢尺來完成對液位儀測量的初始標定，所以液位儀安裝位置應保持同檢尺孔在同一圓周上，且盡量靠近檢尺孔，以保證兩者的測量基準基本相同。</span> </p> <p> <span style="font-size:16px;">● 對新建罐，要求在罐底的液位儀重錘位置，安裝防沖擋板，上下對心。防沖擋板直徑在300 毫米，高度在200 毫米。</span> </p> <p> <br /> </p><h1> <span style="font-size:16px;">油罐液位測量的變遷</span> </h1> <p> <span style="font-size:16px;">在中石油及中石化的成品油流通行業(yè)，對油罐油量的測量大多采用<span style="color:#E53333;"><strong>人工爬罐</strong></span>，投尺進行測量。</span><span style="font-size:16px;">用帶有重錘的米制鋼帶卷尺或帶有刻度的標尺計量，手工記錄讀數(shù)，人工查表換算，再得到油量數(shù)據(jù)。</span><span style="font-size:16px;">這種測量方法不僅勞動強度大，同時存在不安全因素，也無法保證精度。</span> </p> <p> <span style="font-size:16px;">個別地方有用<strong><span style="color:#E53333;">電容式/擴散硅壓力式液位計測量</span></strong>，由于這類傳感器零漂移嚴重，測量偏差大，長期工作穩(wěn)定性差，不受用戶歡迎。</span> </p> <p> <span style="font-size:16px;">也有的地方采用等壓式<strong><span style="color:#E53333;">皮膜液位計或機械式浮子液位計</span></strong>。但因皮膜式液位計受溫度影響大，且存在漏氣問題，機械浮子液位計又經(jīng)常出現(xiàn)鋼帶卡死現(xiàn)象，所以都沒有得到很廣的應用。</span> </p> <p> <span style="font-size:16px;">現(xiàn)在多</span><span

磁致伸縮液位計由電子倉內(nèi)電子電路產(chǎn)生一起始脈沖，此起始脈沖在波導絲中傳輸時，同時產(chǎn)生了一沿波導絲方向前進的旋轉(zhuǎn)磁場，當這個磁場與磁環(huán)或浮球中的長久磁場相遇時，產(chǎn)生磁致伸縮效應，使波導絲發(fā)生扭動，這一扭動被安裝在電子倉內(nèi)的拾能機構(gòu)所感知并轉(zhuǎn)換成相應的電流脈沖，通過電子電路計算出兩個脈沖之間的時間差，即可精確測出被測的位移和液位。特點具有精度高、穩(wěn)定性好、可靠性高、輸出信號多樣、使用壽命長、安全可靠等優(yōu)點。應用范圍磁致伸縮液位計廣泛應用于工業(yè)過程控制、石油加工、制藥、食品加工、水處理、加油站、研磨機械、閥門開度控制等領域中的液位、溫度、密度、界面情況等物理參數(shù)的監(jiān)測、警報與控制。</span>
