摘要
A fuel dispenser includes vapor and hydrocarbon concentration sensors positioned in the vapor recovery line to provide accurate feedback relating to the speed and concentration of hydrocarbon laden vapor recovered by a vapor recovery system. The sensors provide diagnostic information about the vapor recovery process as well as insuring that the vapor recovery process is carried out in an efficient manner. Additionally, the sensors may be positioned in an underground storage tank vent apparatus to monitor fugitive emissions from the underground storage tank.
