<p>Device for transferring liquid, with degassing and measuring, particularly for hydrocarbons, comprising, from upstream to downstream, a pressurised supply (2), a vessel (3) surmounted by a bell-shaped degassing chamber (18), a float (8) placed in the said bell-shaped chamber and actuating a valve (9) controlling the degassing orifice (10) connecting the vessel to a degassing volume (4, 12) communicating with the free air, a volumeter (5) interposed between the vessel (3) and the liquid outlet (19) on which is provided a stop valve (6) subjected, on one side, to the pressure of the liquid and, on the other side, to the pressure prevailing in the degassing volume (4, 12). The volume (4, 12) communicates with the free air or with atmospheric pressure solely via a calibrated escape orifice with a cross section of less than 3 mm<2> for supply pressures greater than 1 bar and capable of reaching 3 to 5 mm<2> when the supply pressure is between 1 and 0.1 bar. <IMAGE></p> |
