Abstract
A vapor recovery system recovers fuel vapor and includes 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. One or more controllers 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.
