PCT No. PCT/FR96/01217 Sec. 371 Date Feb. 3, 1998 Sec. 102(e) Date Feb. 3, 1998 PCT Filed Jul. 29, 1996 PCT Pub. No. WO97/06095 PCT Pub. Date Feb. 20, 1997A method of recovering vapor emitted in a liquid dispensing installation comprising: liquid dispensing means (PL) adapted to cause said liquid to flow with a liquid flowrate QL; vapor recovery means (PV) adapted to cause said vapor to flow with a vapor flowrate QV along a pipe (120), said vapor flowrate QV being controlled by a parameter G. According to the invention, the method includes the following steps: establishing an equation G=F (QV, {pi}) relating the parameter G to the vapor flowrate QV and to parameters pi characteristic of the recovery means and said pipe (120); determining an initial value {pi}o of the parameters pi; on each dispensing k of liquid: measuring the liquid flowrate QLk and determining a value Gk of the parameter G from the equation: Gk=F (QLk, {pi}k-1); determining a new value {pi}k of the parameters pi to be used for the next dispensing k+1 of liquid. Application to dispensing fuel for motor vehicles.
