>> 美國Dynaflow----ABS聲學(xué)氣泡譜分計(jì)
針對(duì)小型氣泡，可通過接觸或者非接觸的方式對(duì)液體中的氣泡進(jìn)行測(cè)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(cè)方便觀察。
特點(diǎn)：
Ø 運(yùn)用聲學(xué)原理對(duì)即使非常小的氣泡也異常敏感
Ø 無需光學(xué)透明液體或容器
Ø 從顆粒中分辨出泡沫
Ø 基于計(jì)算機(jī)使用習(xí)慣的操作平臺(tái)，方便的圖形界面
Ø 測(cè)量方便、快速
Ø 可通過對(duì)比進(jìn)行技術(shù)驗(yàn)證
Ø 近似實(shí)時(shí)的精準(zhǔn)測(cè)量反饋
Ø 易操作的用戶系統(tǒng)
Ø 侵入/非侵入式皆可

Ø • Built on a PC Windows platform with a
Ø user-friendly graphical interface
Ø • Measurements are easily and rapidly
Ø conducted
Ø • Validated by comparison with
Ø microphotography
Ø • Near real-time measurement
Ø • Cost effective
Ø • User-friendly system
