Suction LysimetersCOMPANY : SOLI MEASUREMENT, USA
Suction lysimeters collect pore water from unsaturated soil. After installation below ground level, vacuum is applied to the lysimeter through tubing leading from the lysimeter to the ground surface. The negative air pressure created inside the lysimeter draws pore water into the lysimeter through the porous, stainless steel section of the lysimeter. The pore water is transported to the surface by applying positive pressure to the lysimeter through a second tube. At the surface the pore water is collected in a collection bottle. Suction lysimeters perform best in moist soil and below the water table. Pore water collection from relatively dry formations (pressure potential less than -500 mbar) is difficult.
