Electric piezometer

The understanding of pore water pressure is vital in geotechnics because it can determine both subsurface water flow and the mass strength of the underlying strata. Together these give a good indication of both strength and stress from which viable conclusions can be drawn. Suitable for soils with permeability coefficients of K<(10)^-6. They are constructed of stainless steel cylindrical bodies housing an hydraulic chamber, an electrical transducer and a terminal. The hydraulic chamber has cylindrical filter made from a special material allowing it to monitor the external environment.
