style="text-indent:25px">存于各種容器內(nèi)的液體表面高度及所在的位置稱為液位；固體顆粒、粉料、塊料的高度或表面所在位置稱為料位。兩者統(tǒng)稱為物位。超聲波測量物位是根據(jù)超聲波在兩種介質(zhì)的分界面上的反射特性而工作的。根據(jù)發(fā)射和接收換能器的功能，超聲波物位傳感器可分為單換能器和雙換能器兩種。單換能器在發(fā)射和接收超聲波時均使用一個換能器，而雙換能器對超聲波的發(fā)射和接收各由一個換能器擔(dān)任。超聲波傳感器可放置于水中，讓超聲波在液體中傳播。由于超聲波在液體中衰減比較小，所以即使產(chǎn)生的超聲波脈沖幅度較小也可以傳播。超聲波傳感器也可以安裝在液面的上方，讓超聲波在空氣中傳播，這種方式便于安裝和維修，但超聲波在空氣中的衰減比較厲害。如果從發(fā)射超聲波脈沖開始，到接收換能器接收到反射波為止的這個時間間隔為已知，就可以求出分界面的位置，利用這種方法可以實現(xiàn)對物位的測量。超聲波物位傳感器具有精度高、使用壽命長、安裝方便、不受被測介質(zhì)影響、可實現(xiàn)危險場所的非接觸連續(xù)測量等優(yōu)點。其缺點是：若液體中有氣泡或液面發(fā)生波動，便會有較大的誤差。在一般使用條件下，它的測量誤差為士，測量范圍為10-2-104m。寧夏地質(zhì)災(zāi)害監(jiān)測超聲波物位計特點</p></div>
