智能雷達(dá)物位計的標(biāo)準(zhǔn)安裝包括：標(biāo)記應(yīng)指向罐壁，安裝標(biāo)記應(yīng)位于法蘭的兩個螺釘孔的正當(dāng)半中腰；法蘭的定位方向，為了準(zhǔn)確認(rèn)位，在法蘭或螺絲扣上均有標(biāo)記，在安裝時，此標(biāo)記務(wù)必合乎：1.法蘭的指使標(biāo)記應(yīng)指向罐壁或罐的中心;2.如運用導(dǎo)波管安裝，法蘭標(biāo)記應(yīng)指向開孔的一側(cè);3.如運用旁通管安裝，法蘭標(biāo)記應(yīng)與指向連通管的一側(cè); </p> <p> 智能雷達(dá)物位計在運用過程中，回波信號的幅度表清楚安裝位置是否zui佳，在固體料應(yīng)用途合假如回波信號幅度較低可轉(zhuǎn)動法蘭，每每轉(zhuǎn)動一個孔位使干擾回波達(dá)到zui小。額外還可以經(jīng)過虛假回波儲存，達(dá)到*好勘測效果; </p> <p> 操作步驟如下所述： </p> <p> （1) 在敞開儲罐的過程連署之前，務(wù)必明確承認(rèn)罐內(nèi)無壓力，并無有害媒介; </p> <p> （2) 應(yīng)明確承認(rèn)器皿內(nèi)空罐或料位剛好遮蓋罐底的事情狀況下施行定位調(diào)試，料位較少的事情狀況下也可施行定位調(diào)試；可經(jīng)過虛假回波儲存，對雷達(dá)物位計回波信號施行優(yōu)化; </p> <p> （3) 將法蘭標(biāo)記轉(zhuǎn)動一個孔位，或?qū)⒙萁z扣轉(zhuǎn)動1/8圈，注意回振幅度，接著旋轉(zhuǎn)法蘭或螺絲扣，一直到轉(zhuǎn)動一圈截止，在回波信號*佳位置定位; </p> <p> （4) 在zui優(yōu)位置固定好法蘭或擰緊螺絲扣，若有不可缺少，改易嚴(yán)密封閉圈。 </p><p> 超聲波物位計測量料位的極限值: </p> <p> 1)zui高料位 </p> <p> 當(dāng)一束超聲波脈沖向物料表面?zhèn)魉瓦^程中，若收到從物料表面來的反射波，將無法進(jìn)行測量，這段距離就是盲區(qū)。物料zui高料位不得高于盲區(qū)。 </p> <p> 2)zui低料位 </p> <p> zui低料位也就是使超聲波能到達(dá)的距離傳感器的zui遠(yuǎn)距離，并且使反射回波能被傳感器接收。由于超聲波在傳播過程中的衰減以及物料表面對聲波的吸收，這一傳播距離對物料性質(zhì)依賴性很強(qiáng)，對于DU33來說，可測液體范圍為25m，固體范圍為15m。 </p> <p> 總之，只要儀表選型、安裝適當(dāng)，超聲波物位計的應(yīng)用效果還是比較滿意的。 </p> <p> 超聲波類儀表(超聲波流量計)是現(xiàn)代科學(xué)技術(shù)在工業(yè)測量中的具體運用，是高新電子技術(shù)和聲學(xué)原理相結(jié)合的產(chǎn)物。比起常規(guī)儀表，它們的智能化更高，應(yīng)用的技術(shù)更先進(jìn)，也給用戶帶來更大方便。非接觸式微波物位計常用喇叭或桿式天線來發(fā)射與接收微波，儀表安裝在料倉頂部，不與被測介質(zhì)接觸。</p><div

</p> <p> (1)介質(zhì)及環(huán)境溫度的影響 </p> <p> 超聲波從物料表面反射時，其反射頻率會受到物料溫度的影響而發(fā)生變化，為了補償這一變化，超聲波探頭內(nèi)裝有溫度傳感器，當(dāng)探頭向處理器發(fā)送反射信號的同時，也把溫度信號送到微處理器，處理器將自動補償由于溫度對料位測量的影響。 </p> <p> 此外，為了保證探頭的可靠工作，要求環(huán)境溫度不超過60℃。 </p> <p> (2)攪拌器對物位計測量的影響 </p> <p> 如果物料容器內(nèi)裝攪拌器，它同樣會反射超聲波信號，造成假反射回波，并被傳送到微處理器。微處理器將根據(jù)統(tǒng)計學(xué)原理處理真假面具回波，所以要求超聲波從物料表面反射的回波應(yīng)至少為從攪拌器臂反射的回波的3倍。適當(dāng)降低攪拌器的轉(zhuǎn)速，或?qū)⑻筋^偏離攪拌中心，都可以有效消除攪拌器產(chǎn)生的假面反射對料位測量的影響。儀表的傳感器與灌壁及被測介質(zhì)形成導(dǎo)納值，電路單元將測量導(dǎo)納值轉(zhuǎn)換成物位信號輸出，實現(xiàn)物位測量。寧夏電容式物位計**</p><p
