Piezometers are used for measuring pore pressures in ground.

Hydraulic piezometers consist of a porous filter enclosing a reservoir of water, which is separated from a pressure gauge by flexible, water filled tubes.  The tubes are used to circulate water through the system, removing air and ensuring that the reservoir remains full of water.

Geotechnical Observations’ flushable piezometer is a hydraulic piezometer that can measure positive and negative pore water pressures.

Standard out diameter 32mm .
