This application relates to a leak detector device (100) for detecting an internal leak in a fluid path. The leak detector comprises a housing (110) with a flow passage (120) extending through the housing (110), one or more pairs of temperature sensors (130, 140) for detecting a temperature difference between an outside of the housing (110) and the flow passage (120), one temperature sensor of each pair being arranged towards an outer surface of the housing (110) and the other temperature sensor of the pair being arranged towards an innersurface of the housing (110) that faces the flow passage (120), and an array of electrically conductive wires (150, 160) that extend across the flow passage (120). The array of electrically conductive wires (150, 160) comprises one or more positive polarity wires and one or more negative polarity wires. The application further relates to a corresponding method of leak detection.

A system is provided for collection, detection and containment of leaked liquid. The system may include a spout connected to a liquid cooling manifold for channeling liquid. The system may also include a collection tray positioned under the spout and configured to contain the liquid from the spout. The system may further include a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid.

In a method for detecting the presence of water or additional water, which exists because of a leak, the following steps are carried out: attaching at least one pair of electrodes to/in an object, to/in the presence of water is to be determined; applying an electrical voltage between the electrodes; testing whether electrical current or electrical current that is increased relative to a basic current flows between the electrodes; and detecting the presence of water in the case of flowing current. When implementing the method, at least two electrodes are used, wherein one electrode can be a ground. The electrodes are arranged separated from one another. DC or AC voltage is applied to the electrodes by a device. The device detects a measured value corresponding to the intensity of the current flowing between the electrodes.
