  These Sand/Gravel Permeameters were designed to determine the coefficient of permeability by the constant head method for the laminar flow of water through granular soils. The distance between manometer ports is the same as the diameter.

The permeameter features two manometer ports that are grooved and screened on the inside. The screens (100 mesh stainless steel) are used to prevent migration of material through the valves and tubing during testing. The chamber is acrylic to permit viewing of the sample during the test. End caps and clamping ring are anodized aluminum. Each chamber is equipped with valves; a choice of either porous stones or perforated screens; and tubing for connection to a water source, vacuum and manometer tubes. A spring is incorporated into the top cap to apply 5-10 lbs. force against the top stone or screen to prevent soil density changes during the test.
