超聲流量計（以下簡稱USF）是通過檢測流體流動時對超聲束（或超聲脈沖）的作用，以測量體積流量的儀表。本文主要針對用于測量封閉管道液體流量的USF。
      封閉管道用USF按測量原理分類有：①傳播時間法；②多普勒效應法；③波束偏移法；④相關法；⑤噪聲法。本文將討論用得zui多的傳播時間法和多普勒效應法的儀表。
一、優點： 
      USF可作非接觸測量。夾裝式換能器USF可無需停流截管安裝，只要在既設管道外部安裝換能器即可。這是USF在工業用流量儀表中具有的*優點，因此可作移動性（即非定點固定安裝）測量，適用于管網流動狀況評估測定 
      USF為無流動阻撓測量，無額外壓力損失。 
      流量計的儀表系數是可從實際測量管道及聲道等幾何尺寸計算求得的，既可采用干法標定，除帶測量管段式外一般不需作實流校驗。 
      USF適用于大型圓形管道和矩形管道，且原理上不受管徑限制，其造價基本上與管徑無關。對于大型管道不僅帶來方便，可認為在無法實現實流校驗的情況下是優先考慮的選擇方案。 
      多普勒USF可測量固相含量較多或含有氣泡的液體。 
      USF可測量非導電性液體，在無阻撓流量測量方面是對電磁流量計的一種補充。 
      因易于實行與測試方法（如流速計的速度-面積法，示蹤法等）相結合，可解決一些特殊測量問題，如速度分布嚴重畸變測量，非圓截面管道測量等。 
      某些傳播時間法USF附有測量聲波傳播時間的功能，即可測量液體聲速以判斷所測液體類別。例如，油船泵送油品上岸，可核查所測量的是油品還是倉底水。

二、缺點：
      傳播時間法USF只能用于清潔液體和氣體，不能測量懸浮顆粒和氣泡超過某一范圍的液體；反之多普勒法USF只能用于測量含有一定異相的液體。 
      外夾裝換能器的USF不能用于襯里或結垢太厚的管道，以及不能用于襯里（或銹層）與內管壁剝離（若夾層夾有氣體會嚴重衰減超聲信號）或銹蝕嚴重（改變超聲傳播路徑）的管道。 
      多普勒法USF多數情況下測量精度不高。 
      國內生產現有品種不能用于管徑小于DN25mm的管道。
