我們一般把聲波頻率超過(guò)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(lái)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(guò)空氣介質(zhì)，在遇到水面時(shí)被反射回來(lái)，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(guò)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。西安柴油液位計(jì)磁致伸縮液位計(jì)具有精度高、穩(wěn)定性好、可靠性高、輸出信號(hào)多樣、使用壽命長(zhǎng)、安全可靠等優(yōu)點(diǎn)。</p><div
