Abstract: The invention relates to a 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 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. 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.

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.

Abstract: A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.
