style="text-indent:25px">物位測量中的微波一般是定向發(fā)射的，通常用波束角來定量表示微波發(fā)射和接收的方向性。波束角和天線類型有關(guān)，也和使用的微波頻率(波長)有關(guān)。對于常用的圓錐形喇叭天線來說，微波的頻率越高，波束的聚焦性能越好，即波束角小，在實際使用中這是十分重要的，低頻微波物位計有較寬的波束，如果安裝不得當(dāng)，將會收到內(nèi)部結(jié)構(gòu)產(chǎn)生的較多的虛假回波，例如：采用4”喇叭天線的26GHz雷達的典型波束角為8°，而5.8GHz 的典型波束角為17°。并且，微波的頻率越高，其喇叭尺寸也可以做的越小，更易于開孔安裝。還沒有頻率高于K波段(24—26GHz)的微波(雷達)物位計。大連物位計供應(yīng)超聲波物位計所能測量的比較大的范圍，反映的是換能器的靈敏度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">電容物位計：頂裝式超聲波液位計由本體(由上、下導(dǎo)管組成）、翻板箱（由紅、白雙色磁性小翻板組成）、浮子（由磁體、頂桿、浮筒組成）以及液位變送器等組成。超聲波液位計由微處理器控制的數(shù)字液位儀表。在測量中超聲波脈沖由傳感器（換能器）發(fā)出，聲波經(jīng)液體表面反射后被同一傳感器接收或超聲波接收，通過壓電晶體或磁致伸縮器件轉(zhuǎn)換成電信號，并由聲波的發(fā)射和接收之間的時間來計算傳感器到被測液體表面的距離。工作原理為：容器內(nèi)的浮筒（按不同介質(zhì)跟壓力針對研制），在下導(dǎo)管中隨液面高度的變更而高低浮動并通過頂桿使磁體在上導(dǎo)管內(nèi)高低挪動，促使本體外的翻板翻動并用紅、白色彩來唆使液面高度,同時液位變送器將液位信號傳遞至把持中心進行液位唆使跟把持,也可通過盤算機進行集中監(jiān)控。</p><p style="text-indent:25px">（微波）物位計自２０世紀(jì)７０年代呈現(xiàn)以來，性價比一勞永逸，當(dāng)初已占物位丈量范疇市場份額的２５％，*次于壓力（差壓）式物位計。電容物位計利用電容量的變化來測量容器內(nèi)介質(zhì)物位的測量儀表，在容器內(nèi)，由電極和導(dǎo)電材料制造的容器壁構(gòu)成了一個電容。對于一個給定的電極，被測介質(zhì)的介電常數(shù)不變時，給電極加一個固定頻率的測量電壓，則流過電容的電流取決于電容電極間介質(zhì)的高度，并與之成比例。電容物位計基于有源的回波測距原理，即波（通常采取微波段）在傳播途中介質(zhì)的介電常數(shù)或多少何外形轉(zhuǎn)變時產(chǎn)生反射。雷達物位計按工作方式劃分，雷達物位計主要分為脈沖式和連續(xù)調(diào)頻式兩種。</p><div

style="text-indent:25px">電容式物位儀表：物位變化時引起電極的電容量變化，利用這個原理構(gòu)成的電容式物位計可以測量導(dǎo)電液和非導(dǎo)電液的液位、非導(dǎo)電顆粒狀固體的料位。兩同軸相互絕緣的導(dǎo)電金屬圓柱中間隔以不導(dǎo)電的介質(zhì)，就構(gòu)成電容器，其電容量為：式中ε為介質(zhì)介電系數(shù)，L為圓筒電極的高度, D和d分別為外電極內(nèi)徑和內(nèi)電極外徑。物位變化引起ε，L，D/d變化，從而引起電容量變化。測出這個變化值就可測出物位。根據(jù)這個道理,用各種不同形狀的電容測量頭,可構(gòu)成多種電容式物位儀表。現(xiàn)代電容式物位儀表采用安全防爆、隔爆的措施，應(yīng)用范圍已擴大到一些化工、石油、輕工部門。電容式物位儀表是電測式物位儀表中應(yīng)用較普遍的一種。超聲波物位計具有很強的針對性。大連物位計供應(yīng)</p><p
