Tensiometer for shallow or deep measurements including vadose zone and aquifers
Patent
·
OSTI ID:678558
A two cell tensiometer is described in which water level in the lower cell is maintained at a relatively constant height, and in equilibrium with the water pressure of materials that surround the tensiometer. An isolated volume of air in the lower cell changes pressure proportionately to the changing water pressure of the materials that surround the tensiometer. The air pressure is measured remotely. The tensiometer can be used in drying as well as wetting cycles above and below the water table. 8 figs.
