Measuring moisture leakage through liquid-carrying hardware
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.
1. A method, comprising:
providing a chamber for calculating an amount of liquid leaked by a specimen having one or more walls that define a compartment, wherein the chamber is comprised of one or more materials impermeable to water;
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 wherein the first opening is further configured to receive a plug to seal the compartment;
providing a second opening disposed in a wall of the chamber for inserting the specimen containing liquid, such that all of the specimen is contained within the compartment, and wherein the specimen containing liquid comprises one or more components of a water cooling hardware system;
providing a removable cover configured to seal the second opening when coupled to the chamber, wherein the removable cover comprises a removable plate coupled to the chamber by one or more fasteners;
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, wherein inserting the specimen 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;
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 percent relative humidity of an environment in which the liquid-carrying specimen is used, 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, wherein calculating the amount of liquid leaked 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 less than or equal to two weeks.
