（1）雷達(dá)料位計(jì)和差壓式液位計(jì)的測(cè)量值均反映的是垂直高度上液體的高度，因此操作人員可以通過(guò)比較雷達(dá)料位計(jì)和差壓式液位計(jì)的測(cè)量差值大小，較直接的判斷回收丁二烯貯罐內(nèi)含水量的多少，及時(shí)進(jìn)行排水操作。同時(shí)，也可給單體回收崗位反饋一定的信息：本單元工藝是否存在異?，F(xiàn)象。 </p> <p> （2）當(dāng)球罐內(nèi)液體液位在35%~75%時(shí)，公式計(jì)算的值與取樣分析值相差較小，而當(dāng)球形貯罐內(nèi)液體液位較低時(shí)，需要對(duì)測(cè)量差值進(jìn)行一定的修正，上海專業(yè)雙腔雷達(dá)料位計(jì)。 </p> <p> （3）從目前的實(shí)踐經(jīng)驗(yàn)來(lái)看，該方法可以作為取樣分析方法的補(bǔ)充手段，上海專業(yè)雙腔雷達(dá)料位計(jì)，不可以完全代替取樣分析。 </p> <p> （4）當(dāng)回丁純度較高時(shí)，如90%以上時(shí)，由公式估算出的回收丁二烯濃度與取樣分析值存在相對(duì)大的差值，需要改變計(jì)算方式。當(dāng)回丁純度較高時(shí)，可近似采用A /B 估算濃度雷達(dá)料位計(jì)采用非接觸式測(cè)量方法，是一種理想的經(jīng)濟(jì)型產(chǎn)品，適用于儲(chǔ)料罐、靜井或外接腔體等.上海專業(yè)雙腔雷達(dá)料位計(jì)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

雷達(dá)料位計(jì)測(cè)量料位的先進(jìn)技術(shù)：(1)回波處理新技術(shù)的應(yīng)用從雷達(dá)料位計(jì)的測(cè)量原理可以知道，雷達(dá)料位計(jì)是通過(guò)處理雷達(dá)波從探頭發(fā)射到介質(zhì)表面然后返回到探頭的時(shí)間來(lái)測(cè)量料位的，在反射信號(hào)中混合有許多干擾信號(hào)，所以，對(duì)真實(shí)回波的處理和對(duì)各種虛假回波的識(shí)別技術(shù)就成為雷達(dá)料位計(jì)能夠準(zhǔn)確測(cè)量的關(guān)鍵因素。(2)測(cè)量數(shù)據(jù)處理：由于液面波動(dòng)和隨機(jī)噪聲等因素的影響，檢測(cè)信號(hào)中必然混有大量噪聲。為了提高檢測(cè)的準(zhǔn)確度，必須對(duì)檢測(cè)信號(hào)進(jìn)行處理，盡可能消除噪聲。經(jīng)過(guò)大量的實(shí)驗(yàn)驗(yàn)證，采用數(shù)據(jù)平滑方法可以達(dá)到滿意的效果。此方法也可有效的克服罐內(nèi)攪拌器對(duì)測(cè)量的影響。(3)雷達(dá)料位計(jì)的特點(diǎn)：由于雷達(dá)料位計(jì)采用了上述先進(jìn)的回波處理和數(shù)據(jù)處理技術(shù)，加上雷達(dá)波本身頻率高，穿透性能好的特點(diǎn)，所以，雷達(dá)料位計(jì)具有比接觸式料位計(jì)和同類非接觸料位計(jì)更加優(yōu)良的性能。①可在惡劣條件下連續(xù)準(zhǔn)確地測(cè)量。②操作簡(jiǎn)單，調(diào)試方便。③準(zhǔn)確安全且節(jié)省能源。④無(wú)需維修且可靠性強(qiáng)。⑤幾乎可以測(cè)量所有介質(zhì)。 </p><p> 安裝導(dǎo)波雷達(dá)料位計(jì)時(shí)注意事項(xiàng)： </p> <p> 安裝時(shí)，請(qǐng)一定記得切斷電源。 </p> <p> 1.當(dāng)使用短脖安裝時(shí)，請(qǐng)注意短脖直徑要大于短脖高度 </p> <p> 2.死區(qū)=探頭參數(shù)死區(qū)+A </p> <p> 3.可以在旁壁管中安裝 </p> <p> 4.比較好把探頭末端與底部固定以保證探頭垂直 </p> <p> 5.不要過(guò)度彎曲探頭 </p> <p> 6.插入探頭時(shí)再開(kāi)口上方至少1米的位置放入探頭避免彎曲 </p> <p> 探頭在罐內(nèi)必須保持垂直，并且要離攪拌等物品一定距離（不要使探頭被攪進(jìn)去） </p> <p> 為保證測(cè)量，不要使纜式探頭載重錘（其他探頭的低部）完全接觸罐底。 </p> <p> 在罐內(nèi)的不連續(xù)的物體將會(huì)對(duì)電磁場(chǎng)產(chǎn)生影響從而影響測(cè)量結(jié)果。 </p> <p> 因此，在選擇安裝位置時(shí)應(yīng)避開(kāi)熱管，罐截面的突然改變，罐壁的加厚和橫梁，焊接縫，黏結(jié)管等等。 </p> <p> <br />

發(fā)射－反射－接收是雷達(dá)式料位計(jì)工作的基本原理。雷達(dá)傳感器的天線以波束的形式發(fā)射小5.8GHz的雷達(dá)信號(hào)。反射回來(lái)的信號(hào)仍由天線接收，雷達(dá)脈沖信號(hào)從發(fā)射到接收的運(yùn)行時(shí)間與傳感器到介質(zhì)表面的距離以及物位成比例。即：h= H–vt/2 式中 h為料位；H為槽高；v為雷達(dá)波速度；t為雷達(dá)波發(fā)射到接收的間隔時(shí)間。高頻雷達(dá)料位計(jì)發(fā)射的電磁波波長(zhǎng)為11mm，是測(cè)量散裝料物位比較好選擇的原因。無(wú)錫專業(yè)生產(chǎn)水滴型雷達(dá)料位計(jì)廠家</p><p

style="text-indent:25px">1．探頭結(jié)疤和頻繁故障的解決方法個(gè)辦法是將探頭安裝位置提高，但是有時(shí)候安裝條件限制，不能提高的情況下，就應(yīng)采用將料位測(cè)量值與該槽的泵聯(lián)鎖的辦法，解決這一難題：將比較高料位設(shè)定值減小0.5m左右，當(dāng)料位達(dá)到該比較高值時(shí)，即可停進(jìn)料泵或開(kāi)啟出料泵。2．雷達(dá)料位計(jì)被淹相應(yīng)的改進(jìn)辦法解決這種問(wèn)題的辦法是將雷達(dá)料位計(jì)改為導(dǎo)波管式測(cè)量。仍在原開(kāi)孔處安裝導(dǎo)波管式雷達(dá)料位計(jì)，導(dǎo)波管高于排汽管0.2m左右，這樣一來(lái)，即使出現(xiàn)料漿從排汽管溢出的惡劣工況，也不會(huì)使料位計(jì)天線被料漿淹沒(méi)，而且避免了攪拌器渦流的干擾及大量蒸汽從探頭處冒出，減少了對(duì)探頭的損害，同時(shí)由于導(dǎo)波管聚焦效果好，接收的雷達(dá)波信號(hào)更強(qiáng)，取得了很好的測(cè)量效果。使用導(dǎo)波管測(cè)量方式，可以改善表計(jì)測(cè)量條件，提高儀表測(cè)量性能,具有很高的推廣應(yīng)用價(jià)值。3．關(guān)于泡沫對(duì)測(cè)量的影響干泡沫和濕泡沫能將雷達(dá)波反射回來(lái)，對(duì)測(cè)量無(wú)影響；中性泡沫則會(huì)吸收和擴(kuò)散雷達(dá)波，因而嚴(yán)重影響回波的反射甚至沒(méi)有回波。當(dāng)介質(zhì)表面為稠而厚的泡沫時(shí)，測(cè)量誤差較大或無(wú)法測(cè)量，在這種工況下，雷達(dá)料位計(jì)不具有優(yōu)勢(shì)，這是其應(yīng)用的局限性。上海專業(yè)雙腔雷達(dá)料位計(jì)</p></p><br
