Abstract: A vertical packaging machine (10) comprises a carcass having a substantially quadrangular plan, a forming tube (12) mounted on one side of said carcass and adapted to create packages of a product through the use of a continuous advancement film (13) supplied by a reel (14) mounted on a shaft (16) and arranged in a housing provided in a side of the carcass adjacent to that on N which said forming tube (12) is mounted, the unwinding of said film from said reel being performed by a motor (17) equipped with an appropriate means for controlling the unwinding of said film (13), said carcass being further equipped with a horizontal flat surface (21) on which the film (13) unwound from said reel is made to transit and change direction by 90° for being then directed towards said forming tube (12).

Abstract: Measuring device (1; 15) for determining the composition of the liquid phase of a liquid-gas mixture includes a duct (2) defining a flow direction (X) of the mixture parallel to the longitudinal development axis (Y) of the duct (2) and a measuring element (4) arranged in the duct (2) and suited to determine the composition of a liquid layer that flows in contact with the internal surface (3) of the duct (2). The internal surface (3) of the duct (2) includes an intercepting surface (5, 5?) suited to convey part of the liquid layer towards the measuring element (4), arranged so that it is incident on the flow direction (X) and developed according to a conveyance trajectory that has a helical section and whose tangent to the outlet end (7, 7?) intersects the measuring element (4).
