　　<strong>超聲波液位計</strong>的使用你是否存在這個(gè)那個(gè)的問(wèn)題，例如超聲波液位計進(jìn)水、現場(chǎng)強干擾、液面波動(dòng)較大等等，如何處理?<div>　　1、超聲波液位計進(jìn)水怎么辦？</div><div>　　參考方法：如何儀表進(jìn)水，開(kāi)機無(wú)顯示，很可能儀表電路板被燒壞，建議把儀器發(fā)回原廠(chǎng)由專(zhuān)業(yè)技術(shù)人員檢查。</div><div>　　2、開(kāi)機后儀表僅有背光，無(wú)任何字符顯示？</div><div>　　參考方法：開(kāi)機后儀表僅有背光，無(wú)其他任何字符顯示此情況一般為程序芯片出錯，建議把儀器發(fā)回原廠(chǎng)進(jìn)行處理。</div><div>　　3、瞬時(shí)流量值波動(dòng)大？</div><div>　　瞬時(shí)流量值波動(dòng)大表現為信號強度波動(dòng)大和本身測量流體波動(dòng)大兩方面。解決方法是調整好探頭位置，提高信號強度(保持在3%以上)保證信號強度穩定，如本身流體波動(dòng)大，則位置不好，重新選點(diǎn)，確保*D后5D的工況要求。</div><div>　　4、<strong>超聲波液位計</strong>液面波動(dòng)較大怎么辦？</div><div>　　參考方法：，加大量程；</div><div>　　第二，用多次測量的平均值；</div><div>　　第三，如果條件允許，可以加一個(gè)管子，測管子里面的液位?；蛘呒友b延伸管。儀表裝在管子上。管子直接到介質(zhì)底部，開(kāi)個(gè)旁通孔，可以很好的解決波動(dòng)、泡沫等問(wèn)題。</div><div>　　5、儀表在現場(chǎng)強干擾下無(wú)法使用？</div><div>　　參考方法：儀表在現場(chǎng)強干擾下無(wú)法使用是由于供電電源波動(dòng)范圍較大，周?chē)凶冾l器或強磁場(chǎng)干擾，接地線(xiàn)不正確。給儀表提供穩定的供電電源，儀表安裝遠離變頻器和強磁場(chǎng)干擾，有良好的接地線(xiàn)。超聲波液位計具有抗干擾性強?？扇我庠O置上下限節點(diǎn)及在線(xiàn)輸出調節，并帶有現場(chǎng)顯示，可選擇模擬量，開(kāi)關(guān)量及RS485輸出，方便的與相關(guān)設施接口。</div><div>　　6、<strong>超聲波液位計</strong>為什么不能用于高溫液位的測量？</div><div>　　參考方法：高溫會(huì )形成霧水變成露珠凝聚在液位計探頭上，這樣會(huì )影響超聲波的發(fā)射與接收，從而影響測量結果，經(jīng)常出現滿(mǎn)量程報警或者其他報警情況。</div><div>　　7、超聲波液位計探頭凝結露珠怎么處理？</div><div>　　參考方法：各個(gè)廠(chǎng)家產(chǎn)品不同，有的廠(chǎng)家技術(shù)成熟，探頭表面帶自清潔功能，露珠很少能凝結！也可以可以考慮以下方法：1，表面涂抹潤滑劑2，傾斜安裝，重力消除露珠。</div><div>　　8、超聲波液位計為什么不適合測量帶有較高壓力罐體設備的液位？</div><div>　　參考方法：高壓作用在換能器表面,導致聲波不能有效輻射,甚至于微波也不能輻射出去.超聲波和微波同屬于雷達系列產(chǎn)品,因原理方面的原因,高壓下,普通功率的都不能工作.但加大功率做特殊處理,深海超聲波仍可以工作,但那代價(jià)太大了.</div>
