Abstract
Apparatus and method for monitoring pressure within a vapor recovery pathway of a vapor recovery fuel system including pressure transducer linked to a radio frequency (RF) transponder. The pressure transducer detects changes in vapor pressure within a vapor recovery pathway pressure and the RF transponder relays the information to a remote site for monitoring. The radio frecuency transponder can be housed within as spacer between the vapor recovery hose and the nozzle, mounted in the nozzle itself, the fuel delivery hose, or externally to any of these elements. The detected changes in vapor line pressure can be relayed to any of the fuel dispenser to actuate adjustments in the dispensing system such as vapor recovery pump speed or other parameters.
