摘要： A vapor recovery system is configured to recover fuel vapor and comprises a vapor recovery line for transporting a stream of fuel vapor from a vehicle tank. A flow meter is arranged in the vapor recovery line for indicating the flow rate of the stream of fuel vapor, and a heated element is arranged in the vapor recovery line. Control means are configured to: detect a cooling exerted on the heated element by the stream of fuel vapor, determine a correction for the detected cooling by weighting said cooling with the flow rate, and decrease or stop the stream of fuel vapor, if the detected cooling is smaller than a predetermined level.
