Abstract
A method of recovering vapors emitted while dispensing liquids into an installation. A characteristic value descriptive of the recovery operation is taken from a calibration table set up during the previous dispensing operation. During the dispensing operation, the liquid flow rate and the vapor flow rate are measured at a predetermined time interval. A new characteristic value is determined on the basis of the calibration table from the previous dispensing operation. The liquid flow rate and new characteristic value are applied to the recovery operation. A coefficient is calculated based on the differences between the measured values of the liquid flow rate and the vapor flow rate. A new calibration table is set up with values calculated using the new characteristic value, the measured flow rates, and the coefficient, in readiness for the next dispensing operation.
