Abstract

Embodiments of the present invention provide moisture measuring systems and methods. According to one embodiment of the present invention, a sealable compartment is used in which a specimen containing liquid can be inserted, such that all of the specimen is contained within the compartment. The relative humidity in the compartment is measured over a duration of time, which can be used to calculate the amount of liquid leaked by the specimen. Embodiments of the present invention can be utilized, for example, to calculate the leakage rate of water-carrying hardware of a cooling system, without having to create a membrane or other isolated sample of materials.

Claims (28)

1. A method for calculating an amount of liquid leaked by a specimen, the method comprising:

providing a chamber having one or more walls that define a compartment;

providing a relative humidity probe disposed in a wall of the chamber, wherein at least a portion of the relative humidity probe is disposed within the compartment and is configured to measure relative humidity within the compartment;

providing a first opening disposed in a wall of the chamber, wherein the first opening is configured to receive a hose and is further configured to receive a plug to seal the compartment;

providing a second opening disposed in a wall of the chamber for inserting a specimen containing liquid, such that all of the specimen is contained within the compartment;

providing a removable cover configured to seal the second opening when coupled to the chamber;

providing a computer system operatively connected to the relative humidity probe, wherein the computer system is configured to receive data signals from the relative humidity probe and calculate an amount of liquid leaked by the specimen;

inserting the specimen into the compartment through the second opening;

drying the compartment with one or more gases inputted into the compartment through the first opening, wherein drying the compartment comprises:

pumping one or more gases into the compartment through a hose inserted into the first opening, such that a percent relative humidity reaches a specified level, and

sealing the first opening by inserting the plug into the first opening; and

calculating, by the computer system, an amount of liquid leaked by the specimen based on change in percent relative humidity measured by the relative humidity probe.

2. The method of claim 1 , wherein the chamber is comprised of one or more materials impermeable to water.

3. The method of claim 1 , wherein the cover comprises a removable plate coupled to the chamber by one or more fasteners.

4. The method of claim 1 , wherein the specimen containing liquid comprises one or more components of a water cooling hardware system.

5. The method of claim 1 , wherein inserting a specimen into the compartment comprises:

filling the specimen with liquid;

sealing one or more openings of the specimen to contain the liquid within the specimen;

inserting the sealed specimen into the compartment through the second opening;

covering the second opening with the removable cover; and

coupling the removable cover to the chamber.

6. The method of claim 1 , wherein the specified level represents a percent relative humidity of an environment in which the liquid-carrying specimen is used.

7. The method of claim 1 , wherein calculating, by the computer system, an amount of liquid leaked by the specimen based on change in percent relative humidity measured by the relative humidity probe comprises:

measuring, by the relative humidity probe, changes in percent relative humidity in the compartment over a duration of time;

calculating, by the computer system, a rate of percent relative humidity increase over the duration of time; and

calculating, by the computer system, an amount of liquid leaked by the specimen during the duration of time.

8. The method of claim 7 , wherein the duration of time is less than or equal to two weeks.

9. The method of claim 7 , wherein the duration of time is greater than or equal to two days and less than or equal to five days.
