雷達(dá)液位計(jì)采用發(fā)射—反射—接收的工作模式。雷達(dá)液位計(jì)的天線發(fā)射出電磁波，儲(chǔ)油罐液位計(jì)哪家好，這些波經(jīng)被測(cè)對(duì)象表面反射后，再被天線接收，電磁波從發(fā)射到接收的時(shí)間與到液面的距離成正比，關(guān)系式如下： </p> <p> D=CT/2 </p> <p> 式中D——雷達(dá)液位計(jì)到液面的距離；C——光速；T——電磁波運(yùn)行時(shí)間，儲(chǔ)油罐液位計(jì)哪家好。 </p> <p> 雷達(dá)液位計(jì)記錄脈沖波經(jīng)歷的時(shí)間，而電磁波的傳輸速度為常數(shù)，則可算出液面到雷達(dá)天線的距離，從而知道液面的液位。 </p> <p> 在實(shí)際運(yùn)用中，雷達(dá)液位計(jì)有兩種方式即調(diào)頻連續(xù)波式和脈沖波式。采用調(diào)頻連續(xù)波技術(shù)的液位計(jì)，功耗大，須采用四線制，電子電路復(fù)雜。而采用雷達(dá)脈沖波技術(shù)的液位計(jì)，功耗低，儲(chǔ)油罐液位計(jì)哪家好，可用二線制的24VDC供電，容易實(shí)現(xiàn)本質(zhì)安全，精zhun度高，適用范圍更廣。超聲波用的是聲波，雷達(dá)用的是電磁波，這才是*大的區(qū)別。而且超聲波的穿透能力和方向性都比電磁波強(qiáng)的多，這就是超聲波探測(cè)現(xiàn)在比較流行的原因。超聲波液位計(jì)的工作原理是通過一個(gè)可以發(fā)射能量波的裝置發(fā)射能量波，由一個(gè)接收裝置接收反射信號(hào)。儲(chǔ)油罐液位計(jì)哪家好</p><div

(1)雷達(dá)液位計(jì)采用一體化設(shè)計(jì)，無可動(dòng)部件，不存在機(jī)械磨損，使用壽命長(zhǎng)。 </p> <p> (2)雷達(dá)液位計(jì)測(cè)量時(shí)發(fā)出的電磁波能夠穿過真空，不需要傳輸媒介，具有不受大氣、蒸氣、槽內(nèi)揮發(fā)霧影響的特點(diǎn)，能用于揮發(fā)的介質(zhì)如粗苯的液位測(cè)量。 </p> <p> (3)雷達(dá)液位計(jì)幾乎能用于所有液體的液位測(cè)量。電磁波在液位表面反射時(shí)，信號(hào)會(huì)衰減，當(dāng)信號(hào)衰減過小時(shí)，會(huì)導(dǎo)致雷達(dá)液位計(jì)無法測(cè)到足夠的電磁波信號(hào)。導(dǎo)電介質(zhì)能很好地反射電磁波，對(duì)VEGAPULS雷達(dá)液位計(jì)，甚至微導(dǎo)電的物質(zhì)也能夠反射足夠的電磁波。介電常數(shù)大于1.5的非導(dǎo)電介質(zhì)(空氣的介電常數(shù)為1.0)也能夠保證足夠的反射波，介電常數(shù)越大，反射信號(hào)越強(qiáng)。在實(shí)際應(yīng)用中，幾乎所有的介質(zhì)都能反射足夠的反射波。 </p> <p> (4)采用非接觸式測(cè)量，不受槽內(nèi)液體的密度、濃度等物理特性的影響。 </p> <p> (5)測(cè)量范圍大，zui大的測(cè)量范圍可達(dá)0~35m，可用于高溫、高壓的液位測(cè)量。 </p> <p> (6)天線等關(guān)鍵部件采用高質(zhì)量的材料，抗腐蝕能力強(qiáng)，能適應(yīng)腐蝕性很強(qiáng)的環(huán)境。 </p> <p> (7)功能豐富，具有虛假波的學(xué)習(xí)功能。輸入液面的實(shí)際液位，軟件能自動(dòng)地標(biāo)識(shí)出液面到天線的虛假回波，排除這些波的干擾。 </p> <p> <br />

?2）清洗時(shí)先打開投入式水位儀鐵管的旋帽,小心拿出液位計(jì)；再將液位計(jì)上附著的雜物（比如水草，浮游生物等）**掉。 </p> <p> ?3）清潔水位計(jì)引壓孔時(shí)，可使用三氯乙烯或酒精注入引壓孔到其高度二分之一處浸泡5分鐘左右，然后輕微晃動(dòng)、重復(fù)多次，直到清洗干凈位止。禁止使用任何器具清洗引壓孔，以免損壞敏感芯子感壓膜片。 </p> <p> ?4）清潔變送器壓力接口和引壓孔時(shí)，忌用硬度過大的刷子或金屬工具，以避免損傷敏感芯子及壓力接口螺紋。 </p> <p> ?5）清洗完畢后將液位計(jì)慢慢的放回鐵管中，感覺已放置鐵管的低部，將旋帽安裝回原處即可。 </p> <p> ?在卸下清洗后重新安裝，因安裝深度會(huì)有一定的變動(dòng)，必須再次比照水閘同一水位當(dāng)時(shí)的水位表尺，對(duì)二次儀表的檢測(cè)值進(jìn)行矯正，以確保采樣數(shù)據(jù)的正確性。 </p><p>

磁翻板液位計(jì)具有優(yōu)良的可靠性和抗腐蝕性，在各種塔、罐、槽等容器內(nèi)的介質(zhì)液位檢測(cè)上受到客戶一致的好評(píng)。當(dāng)然若想它能給你正常工作，一些技術(shù)也是要掌握的。下面主要給大家介紹下磁翻板液位計(jì)的安裝、使用及維護(hù)方法，供學(xué)習(xí)。1.使用前應(yīng)先用校正磁鋼將零位以下的小球置成紅色，其它球置成白色;2.介質(zhì)內(nèi)不應(yīng)含有固體雜質(zhì)或磁性物質(zhì)，以免對(duì)浮子造成卡阻;3.磁翻板液位計(jì)本體周圍不容許有導(dǎo)磁物質(zhì)接近，禁用鐵絲固定，否則會(huì)影響磁翻板液位計(jì)的正常工作;4.磁翻板液位計(jì)安裝必須垂直，磁翻板液位計(jì)與容器引管間應(yīng)裝有球閥，便于檢修和清洗;5.如用戶自行采用伴熱管路時(shí)，必須選用非導(dǎo)磁材料，如紫銅管等。伴熱溫度根據(jù)介質(zhì)情況確定;6.打開底法蘭，裝入磁性浮子(注意：重端帶磁性一端向上，不能倒裝);7.調(diào)試時(shí)應(yīng)先打開上部引管閥門，然后緩慢開啟下部閥門，讓介質(zhì)平穩(wěn)進(jìn)入主導(dǎo)管(運(yùn)行中應(yīng)避免介質(zhì)急速?zèng)_擊浮子，引起浮子劇列波動(dòng)，影響顯示準(zhǔn)確性)，觀察磁性紅白球翻轉(zhuǎn)是否正常，然后關(guān)閉下引管閥門，打開排污閥，讓主導(dǎo)管內(nèi)液位下降，據(jù)此方法操作三次，確屬正常，即可投入運(yùn)行(腐蝕性等特殊液體除外)。浮球液位計(jì)廣使用于煉油、化工、造紙、食品、及污水處理等行業(yè)。甘肅油罐液位計(jì)維保</p><p

我們一般把聲波頻率超過20kHz的聲波稱為超聲波，超聲波是機(jī)械波的一種，它的特征是頻率高、波長(zhǎng)短、繞射現(xiàn)象小，另外方向性好，能夠成為射線而定向傳播。超聲波在液體、固體中衰減很小，因而穿透能力強(qiáng)，尤其是在對(duì)光不透明的固體中，超聲波可穿透幾十米的長(zhǎng)度，碰到雜質(zhì)或界面就會(huì)有明顯的反射，超聲波測(cè)量物位就是利用了它的這一特征。在超聲波檢測(cè)技術(shù)中，不管那種超聲波儀器，都必須把電能轉(zhuǎn)換超聲波發(fā)射出去，再接收回來變換成電信號(hào)，完成這項(xiàng)功能的裝置就叫超聲波換能器，也稱探頭。如圖所示，將超聲波換能器置于被測(cè)液體上方，向下發(fā)射超聲波，超聲波穿過空氣介質(zhì)，在遇到水面時(shí)被反射回來，又被換能器所接收并轉(zhuǎn)換為電信號(hào)，電子檢測(cè)部分檢測(cè)到這一信號(hào)后將其變成液位信號(hào)進(jìn)行顯示并輸出。由超聲波在介質(zhì)中傳播原理可知，若介質(zhì)壓力、溫度、密度、濕度等條件一定，則超聲波在該介質(zhì)中傳播速度是一個(gè)常數(shù)。因此，當(dāng)測(cè)出超聲波由發(fā)射到遇到液面反射被接收所需要的時(shí)間，則可換算出超聲波通過的路程，即得到了液位的數(shù)據(jù)。超聲波有盲區(qū)，安裝時(shí)必須計(jì)算預(yù)留出傳感器安裝位置與測(cè)量液體之間的距離。儲(chǔ)油罐液位計(jì)哪家好</p><p
