Abstract: A fluidic filter for filtering a fluid includes a filter housing having an inlet part, an outlet part and a housing part, and a filter element having an inlet side and an outlet side. The filter element is housed inside the housing part of the filter housing and includes a first flow passage that extends along a longitudinal direction of the filter element and is connected to the outlet part, and a plurality of ridges extending along the longitudinal direction. A plurality of second flow passages respectively are formed between ridges and an inner surface of the housing part, allowing the fluid to flow from the inlet side of the filter element along the longitudinal direction. At least a portion of the plurality of ridges facing the second flow passages is permeable to the fluid so as to allow passage of the fluid from the second flow passages to the first flow passage. A tip portion of each of the plurality of ridges is joined to the inner surface of the housing part along a part of the tip portion of the respective ridge in the longitudinal direction.

Abstract: 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.
