|  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" 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 lb 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 a 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 connections
are included.
