>> 美國Dynaflow----ABS聲學(xué)氣泡譜分計(jì)

針對小型氣泡，可通過接觸或者非接觸的方式對液體中的氣泡進(jìn)行測量，獲得液體中的空隙率、氣泡數(shù)量、大小分布，并能圖表形式輸出結(jié)果，是觀測方便觀察。

特點(diǎn)：

• 運(yùn)用聲學(xué)原理對即使非常小的氣泡也異常敏感
• 無需光學(xué)透明液體或容器
• 從顆粒中分辨出泡沫
• 基于計(jì)算機(jī)使用習(xí)慣的操作平臺，方便的圖形界面
• 測量方便、快速
• 可通過對比進(jìn)行技術(shù)驗(yàn)證
• 近似實(shí)時(shí)的精準(zhǔn)測量反饋
• 易操作的用戶系統(tǒng)
• 侵入/非侵入式皆可
