DESCRIPTION

RST Pneumatic Piezometers monitor pore water pressure in geotechnical applications where stability levels are critical, such as in embankments and slopes. They utilize a direct reading pneumatically operated diaphragm, making operation simple while ensuring long term stability and high accuracy at a low cost. Employing the lowest (0.002 cc) displacement available, measurements can be made under essentially zero volume change conditions. Time lag problems are minimized, and accuracy improved.

APPLICATIONS

  • Assessing performance and investigating stability of earth fill dam embankments.
  • Slope stability investigations.
  • Monitoring water levels in wells and standpipes.
  • Monitoring pressures behind retaining walls and diaphragm walls.
  • Monitoring pressures during fill or excavation.
  • Monitoring pore pressure in land reclamation applications.
