WebJan 1, 2003 · The parameter R5, defined as the ratio of the height of the foam at 5 min after formation to the initial height, is proposed for the evaluation of foam stability. Foams having R5 values higher ... WebThe foam height is measured with a light source and a light sensor. The foam refracts the emitted light and hence, shades the light sensor. The measuring result can be falsified due to contamination of the vessel. Unevenness of the foam height is not recorded. In using these methods of testing foam there is the disadvantage that either the ...
