Abstract
Method for controlling a linear pump () of a vapour recovery system in a fuel dispensing unit (). The linear pump () is flow controlled by a signal. The method comprises applying (SI) a known voltage to a solenoid coil () of the linear pump () for a predetermined time period, measuring (S) a current consumption of the solenoid coil () during the predetermined time period, and adjusting (S) 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 () to a vapour tank.
