  Designed to determine the coefficient of permeability by the constant or falling head method for the laminar flow of water through granular soils. The permeameters are available in five sizes. Shown is the 2.5”(63.4 mm) model.

The chamber is one-piece acrylic to permit viewing of the sample during the test. Sample lengths are easily changed for constant or falling head tests by the use of a spacer that attaches to the top cap spring. This spring is positioned to apply 5 – 10 lbs. force against the top stone or screen to prevent soil density changes during the test.

End caps and clamping ring are anodized aluminum. Each chamber is equipped with valves; either porous stones or perforated screens, depending on the diameter; and tubing for connection to water source, vacuum and manometer tubes.

The manometer tube, scale and permeameter base are attached to a platform creating a compact and portable unit. An adjustable constant head reservoir (Not shown) mounts to the upright scale and can be easily removed. All tubing and connections are included.
