This equipment is used for testing the permeability of granular soils
(sands and gravels).The specimen is formed in a permeability cell and
water is passed through it from a constant level tank Take-off points
located along the sides of the permeability cell are connected to

scale. Water passing through the specimen is collected and
measured, either for a specific quantity or over a period of time. The
reduction of head is noted from the variation of water level in the
manometer tubes. Comprising three glass tubes of constant bore,
metre scale and connecting tubing for cell pressure take-off points,
all mounted on a free-standing panel. Manufactured from
transparent plastic with attachment for wall mounting. The inlet,
