Abstract

The present technology generally relates to a porous medium parameter measurement device comprising a liquid permeable portion comprising a liquid 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 (25)

1. A porous medium parameter measurement device comprising:

i) a liquid permeable portion comprising a liquid permeable component;

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.

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

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

4. The porous medium parameter measurement device as defined in claim 1 , wherein the gas permeable component acts to purge gases trapped in the liquid permeable component.

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

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

7. The porous medium parameter measurement device as defined in claim 1 , wherein the porous medium parameter is ionic concentration.

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

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

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

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

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

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

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

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

16. The porous medium parameter measurement device of claim 1 , wherein the porous medium parameter measurement device comprises a medium solution lacking polymers.

17. A method for measuring a porous medium parameter, the method comprising:

a) inserting the porous medium parameter measurement device as defined in claim 1 into a porous medium comprising a porous medium solution;

b) allowing the porous medium solution to diffuse through the porous medium parameter measurement device; and

c) measuring a porous medium parameter from the porous medium solution comprised in the porous medium parameter measurement device.

18. The method of claim 17 , wherein the porous medium parameter measurement device comprises a medium solution lacking polymers.
