A method and a device for indication of leakage in a liquid system, includes liquid lines and a liquid filter that consists of a non-transparent upper portion (3) having flow paths (5, 6) for the supply of liquid to the filter and discharge of liquid from the filter, and a transparent lower portion (4) having a transparent casing (7) and a filter unit (11) positioned inside the casing (7). It is significant for the device that an indicating channel (27) is connected to the inlet flow path (5), the indicating channel (27) extending below the upper portion (3) and having an outlet opening (31) that emerges in the lower portion (4) and being arranged to discharge supplied liquid so as to be visible to a person's eye and also visually indicate gas bubbles/air bubbles (39) that possibly are present.
Device for indication of leakage in a liquid system, which includes liquid lines and a liquid filter that consists of a non-transparent upper portion having an inlet flow path for the supply of liquid to the filter and an outlet flow path for discharge of liquid from the filter, and a transparent lower portion having a transparent casing and a filter unit positioned inside said casing, wherein an indicating channel located proximate to the transparent casing is connected to the inlet flow path, said indicating channel extending below the upper portion and having an outlet opening that emerges in the lower portion and is arranged to discharge supplied liquid so as to be visible to a person's eye and also visually indicate gas bubbles/air bubbles that possibly are present during occurrence of any leakage.
