WebMay 5, 2024 · If you have to measure the foam density not only frequently but over a long period of time, I'd consider developing an optical method. The attenuation of a low power laser beam passing through a fixed thickness of foam will correlate with the foam density (more bubble walls per cm to scatter the light for a denser foam). WebApr 8, 2024 · Solid Foams. Solid foams are explained as a class of lightweight cellular engineering materials. Typically, these particular foams are classified into two types according to their pore structure: open-cell-structured foams (which is also called reticulated foams) and closed-cell foams. At the high enough cell resolutions, any type can be ...
