Abstract: A device (1) for detecting microleakages from kegs (2) and similar containers containing a liquid with CO2 under pressure is provided with an outlet mouth (21) and a sealing valve (22). The device (1) includes a detection head (10) adapted to seal and couple with the keg (2) at the outlet mouth (21). The detection head (10) includes a measuring chamber (11) adapted to face over the outlet mouth (21). A light source (12) has an infrared component with wavelengths corresponding to CO2 absorption wavelengths facing the measuring chamber (11). A light sensor (13) faces the measuring chamber (11) for detecting the infrared light component with wavelengths corresponding to the CO2 absorption wavelengths emitted in the measuring chamber (11) by the light source (12). The measuring chamber (11) includes at least one air inlet (14) and at least one air vent (15).

Abstract: The present invention refers to a group for the in-line measuring of the quantity of carbon dioxide dissolved in a liquid contained in a closed container such as bottles, jars and so on and to an automatic containers filling plant comprising such measuring group. The measuring group according to the present invention comprises at least one inspection area (20,20?) suitable for housing at least one container (11), at the at least one inspection area (20,20?) being provided at least one laser spectroscopy device (16) for measuring the partial pressure of carbon dioxide present in the head space (13) of a container (11) placed in the at least one inspection area (20,20?), and it is characterised in that at the at least one inspection area (20,20?) there are additionally provided means for mixing (12) the content of said container (11).
