ABSTRACT:
A gasoline vapor recovery system and method in which a flow metering unit is provided for measuring the flow of a mixture of air and gasoline vapor from a vehicle tank and for determining the density of the gasoline vapor in the mixture. A value is provided for varying the flow of the mixture from the tank, and a control unit is operatively connected to the flow metering unit and to the valve for adjusting the position of the valve, and therefore the flow of the mixture from the tank, in response to the density of the gasoline vapor in the mixture and the gasoline flow.
