基本原理
超聲波流量計(jì)的基本原理及類型超聲波在流動(dòng)的流體中傳播時(shí)就載上流體流速的信息。因此通過(guò)接收到的超聲波就可以檢測(cè)出流體的流速，從而換算成流量。
根據(jù)檢測(cè)的方式，可分為傳播速度差法、多普勒法、波束偏移法、噪聲法及相關(guān)法等不同類型的超聲波流量計(jì)。起聲波流量計(jì)是近十幾年來(lái)隨著集成電路技術(shù)迅速發(fā)展才開(kāi)始應(yīng)用的一種非接觸式儀表，適于測(cè)量不易接觸和觀察的流體以及大管徑流量。它與水位計(jì)聯(lián)動(dòng)可進(jìn)行敞開(kāi)水流的流量測(cè)量。使用超聲波流量比不用在流體中安裝測(cè)量元件故不會(huì)改變流體的流動(dòng)狀態(tài)，不產(chǎn)生附加阻力，儀表的安裝及檢修均可不影響生產(chǎn)管線運(yùn)行因而是一種理想的節(jié)能型流量計(jì)。
