Abstract
Method for controlling a linear pump (9) of a vapour recovery system in a fuel dispensing unit (1). The linear pump (9) is flow controlled by a signal. The method comprises applying (SI) a known voltage to a solenoid coil (10) of the linear pump (9) for a predetermined time period, measuring (S2) a current consumption of the solenoid coil (10) during the predetermined time period, and adjusting (S3) the signal based on the measured current consumption. The invention also relates to a vapour recovery system for recovering vapour from a motor vehicle tank via a fuel dispensing nozzle (7) to a vapour tank.
