Abstract (en)

[origin: WO0190724A1] A multi-directional permeameter apparatus is disclosed for the purpose of determining the coefficients of permeability by utilizing a constant (or falling) head method for the laminar flow of a fluid, such as water, through a specific material or sample which is being tested. The apparatus includes a mold removably secured to a base. A lid is removably secured to the mold to render a device which can be used for compaction as well as testing. Inlet and outlet ports are located in the apparatus for allowing fluid flow to occur in both the horizontal plane and the vertical plane for determining the coefficients of permeability of a particular sample either horizontally, vertically, or simultaneously horizontally and vertically.
