VAPOR RECOVERY DETECTION MEANS

摘要

A vapor recovery system for recovering fuel vapor from a vehicle tank during dispensing of fuel into the vehicle tank. The vapor recovery system comprises a vapor recovery line for transporting fuel vapor, and detecting device for detecting a fuel vapor flow. The detecting device comprises a housing having a vapor inlet and a vapor outlet, a body movably arranged in the housing, and a sensor arranged to detect a location of the body within the housing. The body is configured to move from a first position in the housing to a second position in the housing in dependence of a rate of fuel vapor flow flowing from the vapor inlet to the vapor outlet.
