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.

A method for controlling a linear pump of a vapour recovery system in a fuel dispensing unit, the linear pump being flow controlled by a signal, wherein the method comprises:
- applying a known voltage to a solenoid coil of the linear pump for a predetermined time period,
- measuring a current consumption of the solenoid coil during the predetermined time period, and
- adjusting the signal based on the measured current consumption.
A vapour recovery system for recovering vapour from a motor vehicle tank via a fuel dispensing nozzle to a vapour tank, comprising:
- a linear pump configured to pump vapour from the motor vehicle tank to the vapour tank, the linear pump being flow controlled by a signal applied to a solenoid coil;
- and
- a control unit configured to adjust the signal based on a measured current consumption of the solenoid coil.
