<p>The invention concerns a filling station fuel dispenser operating with a turbine-type counter (12) whereof the data concerning the volume delivered are corrected by elimination of the error introduced by the action of the fluid viscosity. The correction is carried out by means of a computer (17) receiving the data coming from the counter (12) and those of a sensor (16) measuring the pressure developed at the junction (15) of a hydraulic circuit (19) comprising a restrictor (13) and a coil pipe (14) arranged in series and supplied in output flow by the pump (4) pressure (P). The circuit (19) is placed in the gas-freeing tank (10) and flows out therein. For a stabilised feeding pressure (P), the pressure (p) at the junction (15) is practically a function of a fuel viscosity alone.</p> |
