1. A system for detecting at least one of a liquid in an area and the liquid exiting the area, the system comprising:
- a first conductor; and
a second conductor;
wherein;
absent the liquid, a magnitude of an impedance between the first conductor and the second conductor is greater than a threshold;
a first portion of the first conductor and a second portion of the second conductor are positioned along a boundary of the area, the first portion is positioned a first distance from the second portion;
a third portion of the first conductor and a fourth portion of the second conductor are positioned within the boundary, the third portion is positioned a second distance from the fourth portion; and
in a presence of the liquid, the magnitude of the impedance between the first conductor and the second conductor is less than the threshold thereby indicating that the liquid is at least one of positioned within the boundary and the liquid is positioned outside the boundary.

Abstract
Systems and methods for detecting a liquid. Detection a liquid may include detecting liquid at a boundary of an area and reporting the presence of the liquid. Reporting liquid at a boundary may prevent leaking of the liquid from the area. Detecting also includes detecting liquid inside the area. The amount of liquid detected inside the boundary may relate to a range of amounts of liquid. The minimum amount of the range may represent the minimum amount of liquid that is permissible in the area prior to taking action to deal with the liquid.

15. A system for detecting a liquid, the system comprising:
-
a first conductor; a second conductor; and a processing circuit, the processing circuit electrically couples to the first conductor and the second conductor;
wherein;a magnitude of an impedance of the first conductor and a magnitude of an impedance of the second conductor is less than a magnitude of an impedance per unit area of the liquid; the first conductor is positioned a first distance away from the second conductor; the liquid spans the first distance between the first conductor and the second conductor and contacts the first conductor and the second conductor; the processing circuit; determines a magnitude of an impedance of an electrical circuit that includes a portion of the first conductor, a portion of the second conductor, and the liquid; compares the magnitude of the impedance to a threshold to detect a presence of the liquid; and relates the impedance of the electrical circuit to a chemical composition of the liquid. - View Dependent Claims (16, 17)
