  • Balloon Density Apparatus are used for the on-site determination of the density of well bonded soil according to the ASTM and French standards respectively.
  • UTS-0990A consists of a graduated cylinder of 1596 ml capacity housed inside an aluminium guard, a reversible rubber aspirator pump, a density plate 9 inches square, and 12 rubber balloons.
  • The principle of operation is similar to the sand replacement but the hole is filled by a rubber balloon where water is pumped.
  • The amount of water can be easily determined by the graduation of the cylinder.
  • According to NF standard, a metal cylinder is filled with water which is then pumped into a rubber membrane mounted on the base of the cylinder.
  • The water pressure is controlled by a pressure gauge and the volume of the balloon is measured on the graduated piston stem.
