Foam index test

WebAlthough a foam index (FI) test has been devised to measure the effect of CCA’s on AEA, it is based on visual observations and non-standardized methods prone to misinterpretation and/or imprecision. WebThe Foamscan is designed to measure the ability of a liquid to generate foam by sparging a gas through the liquid. It will also determine persistence of the generated foam by measuring variation in its volume, density, and drainage rate. The Foamscan FMS-HTMP works at a temperature up to 120°C and a pressure up to 8 bar.
