超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)测(ce)量物(wu)位是根据超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)两种(zhong)介质的(de)(de)分(fen)界(jie)面上的(de)(de)反射(she)特性而工作的(de)(de)。根据发射(she)和接收(shou)换(huan)能(neng)(neng)器(qi)(qi)的(de)(de)功能(neng)(neng)，超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)物(wu)位传感器(qi)(qi)可(ke)(ke)分(fen)为(wei)单(dan)换(huan)能(neng)(neng)器(qi)(qi)和双(shuang)换(huan)能(neng)(neng)器(qi)(qi)两种(zhong)。单(dan)换(huan)能(neng)(neng)器(qi)(qi)在(zai)(zai)发射(she)和接收(shou)超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)时均使(shi)用一(yi)个换(huan)能(neng)(neng)器(qi)(qi)，而双(shuang)换(huan)能(neng)(neng)器(qi)(qi)对超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)的(de)(de)发射(she)和接收(shou)各由(you)一(yi)个换(huan)能(neng)(neng)器(qi)(qi)担任(ren)。超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)传感器(qi)(qi)可(ke)(ke)放置于(yu)水(shui)中(zhong)，让(rang)超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)液(ye)体(ti)中(zhong)传播。由(you)于(yu)超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)液(ye)体(ti)中(zhong)衰(shuai)减比较(jiao)小，所以即使(shi)产(chan)生的(de)(de)超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)脉冲幅度(du)较(jiao)小也可(ke)(ke)以传播。超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)传感器(qi)(qi)也可(ke)(ke)以安(an)(an)装在(zai)(zai)液(ye)面的(de)(de)上方，让(rang)超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)空气中(zhong)传播，这种(zhong)方式(shi)便于(yu)安(an)(an)装和维(wei)修，但超(chao)(chao)声(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)空气中(zhong)的(de)(de)衰(shuai)减比较(jiao)厉害。
