Piezopress
The Piezopress system (PZP) consists of individual PVC piezometer tubes with removable pressure sensors. With the tight sensor seat above the filter tip, a closed cell is created at measurement interval depth. Thus, the pore water pressure can be monitores even in low permeability rocks and soils.
The Piezopress is a low-cost pore water pressure measurement system for boreholes from a diameter of 50 mm.
