Abstract

A system for detecting a leak in a condensate generating device, the system including a pH sensor configured for measuring the pH of a condensate of the condensate generating device; and a controller operably connected to the pH sensor, the controller configured for measuring a rate of pH change over time of the condensate and a pH level of the condensate, wherein if the rate of pH change over time is greater than the pre-determined rate of pH over time and the pH level is greater than the pre-determined pH level, a leak in the condensate generating device is determined to have occurred.

First claim

What is claimed herein is:

1. A system for detecting a leak in a condensate generating device, said system comprising:
(a) a pH sensor configured for measuring the pH of a condensate of the condensate generating device; and
(b) a controller operably connected to said pH sensor, said controller configured for measuring a rate of pH change over time of the condensate and a pH level of the condensate,

wherein when said rate of pH change over time is greater than a pre-determined rate of pH over time and said pH level is greater than a pre-determined pH level, the controller determines that a leak in the condensate generating device has occurred.

2. The system of claim 1 , wherein said pre-determined rate of pH change over time is an increase of pH of about 2 over a period of about 5 minutes.

3. The system of claim 1 , wherein said pre-determined pH level is about 4.

4. A method for detecting a leak in a condensate generating device having a pH sensor configured for measuring the pH of a condensate of the condensate generating device, said method comprising:
(a) comparing a rate of pH change over time to a pre-determined rate of pH change over time of the condensate; and
(b) comparing a pH level of the condensate to a pre-determined pH level,
wherein when said rate of pH change over time is greater than said pre-determined rate of pH over time and said pH level is greater than said pre-determined pH level, a leak in the condensate generating device is determined to have occurred.

5. The method of claim 4 , wherein said pre-determined rate of pH change over time is an increase of pH of about 2 over a period of about 5 minutes.

6. The method of claim 4 , wherein said pre-determined pH level is about 4.
