S245-01 Constant head

( Soil )

  • BS 1377:5
  • ASTM D2434
  • AASHTO T215

Used to determine the permeability of granular, gravel and sand soils. The specimen is formed in an acrylic permeability cell, and water is passed through it from a constant level tank. The permeability cell has pressure points at different levels which are connected to the manometer tubes fixed on a stand with graduated scale. Two constant head permeability cells, formed by an acrylic plexiglass body held between two aluminium anodized end plate, are available:

  • S245-01:  cell Ø 75 mm, three pressure take-off points. Weight: 3 Kg
  • S245-02: cell Ø 114 mm six pressure take-off points. Weight: 7 Kg. When using this cell, two manometer tube stands mod.S245-03 are required.

To perform the permeability test it is also necessary to order:

  • S245-03:manometer tubes and stand, comprising three tubes of constantbore, graduated scale, tubing and connectors. Dimensions: 210x50x1160 mm Weight: 5 kg approx.
  • S245-04: constant level tank, made from acrylic plexiglass, wall mounting.The inlet, outlet and overflow pipes can be adjusted for height
    within the tank. Weight: 3 kg approx.
