Abstract

The present technology generally relates to a porous medium parameter measurement device. The porous medium parameter measurement device comprises: a liquid permeable portion comprising a fluid permeable component and a polymer swellable solution; and comprises a gas permeable portion comprising a gas permeable component. The liquid permeable portion is in operative communication with the gas permeable portion through the gas permeable component; and the gas permeable component acts to purge gases from the liquid permeable component and the polymer swellable solution.

Claims (27)

1. A porous medium parameter measurement device comprising:

i) a liquid permeable portion comprising a liquid permeable component and a polymer swellable solution;

ii) a gas permeable portion comprising a gas permeable component;

wherein the liquid permeable portion is in operative communication with the gas permeable portion through the gas permeable component; and

wherein the gas permeable component acts to purge gases from the liquid permeable component and the polymer swellable solution.

2. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in operative communication with the porous medium.

3. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in gas communication with the porous medium.

4. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component acts to purge gases trapped in: i) the liquid permeable component, ii) the polymer swellable solution, or iii) both i) and ii).

5. A porous medium parameter measurement device as defined in claim 1 , wherein the porous medium is soil.

6. A porous medium parameter measurement device as defined in claim 1 , wherein the porous medium parameter is water tension in the porous medium.

8. A porous medium parameter measurement device as defined in claim 1 , wherein the liquid permeable portion is impermeable to gases.

9. A porous medium parameter measurement device as defined in claim 1 , wherein the liquid permeable portion is impermeable to air.

10. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable portion is permeable to gas and impermeable to liquids.

11. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable portion is permeable to air and impermeable to liquids.

12. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in contact with the liquid permeable component.

13. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in contact with the polymer swellable solution.

14. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in contact with the liquid permeable component and the polymer swellable solution.

15. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in operative communication with the liquid permeable component.

16. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in operative communication with the polymer swellable solution.

17. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is in operative communication with the liquid permeable component and the polymer swellable solution.

18. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable portion is hydrophobic.

19. A porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component is a hydrophobic membrane.
