Abstract:     An apparatus for sensing the hydrocarbon concentration of the return vapor flow of a fuel dispenser equipped with a vapor recovery system. The apparatus includes a sensing housing positioned adjacent the vapor return passage so as to provide fluid communication with the return vapor flow and to discourage entry of liquid into the sensing housing and a vapor inlet positioned in the vapor return passage for admitting hydrocarbon vapor into the sensor chamber. Desirably, the sensing housing is angled to the vapor flow within the vapor return passage.
