A dispensing system for dispensing volatile liquids such as hydrocarbon fuel for vehicles into a tank having a filler neck also collects the vapors to reduce atmospheric pollution. A fuel delivery hose includes a hand-held fuel valve and nozzle for insertion in the opening of the tank. A means delivers fuel under pressure to the fuel delivery hose, and another means provides electrical pulses corresponding to the volumetric flow of liquid through the fuel delivery hose when the fuel valve is open. A vapor recovery hose includes a vapor intake connected to the hand-held nozzle for insertion in the opening of the tank without sealing with the tank, and a motor driven vapor pump produces a volumetric flow through the vapor recovery hose corresponding to a signal applied to the motor. A processing means produces the signal applied to the motor in response to the electrical pulses to produce a volumetric flow of vapor slightly greater than the volumetric flow of fuel to the tank.

Vapor recovery fuel dispenser for multiple hoses

A fuel dispensing system and method for preventing unauthorized fueling by controlling access and delivery of fuel from a fuel dispenser, based on information received from a vehicle or container via remote communications during a fueling operation. The vehicle transmits a signal including fuel delivery indicia to the dispenser. The dispenser uses the fuel delivery indicia to determine whether the vehicle is receiving fuel and determines whether it is delivering fuel. The dispenser maintains fuel delivery authorization if the vehicle indicates that it is receiving fuel and the dispenser is delivering fuel. If the vehicle indicates that it is not receiving fuel and the dispenser determines that it is delivering fuel, the dispenser may generate an output signal to identify an improper fueling condition and stop fuel delivery.

Dispensing system for preventing unauthorized fueling

A fuel dispensing system compensates for varying fuel source flow rate requirements based on fuel dispenser feedback signals. A pumping system pumps fuel from one or more fuel sources to one or more fuel dispensers through associated conduits. When actively dispensing fuel, each fuel dispenser monitors its actual fuel discharge rate and adjusts an integral flow control device to maintain a nominal fuel discharge rate. When an active fuel dispenser fails to achieve its nominal fuel discharge rate, it indicates this condition to the pumping system via its dispenser feedback signal. In response, the pumping system increases its pumping rate until the fuel dispenser achieves its nominal fuel discharge rate. Other active fuel dispensers adjust their flow control devices as needed to maintain their nominal fuel discharge rate in response to the adjusted pumping rate. If multiple active fuel dispensers fail to achieve their nominal fuel discharge rate, the pumping system adjusts its pumping rate until all active dispensers achieve their nominal fuel discharge rate. In some configurations, active fuel dispensers provide a dispenser feedback signal that is proportionate to the actual dispenser fuel discharge rate, and the pumping system proportionately controls its pumping rate.

Fuel dispensing system with discharge rate control

A service station vapor management system including a plurality of vapor handling subsystems and a controller in electronic communication with the vapor handling subsystems for monitoring subsystem operation, determining an overall service station V/L ratio and controlling subsystem operation to maintain the V/L ratio or total site hydrocarbon emissions within predetermined limits.

Site fueling vapor recovery emission management system

A system for monitoring and testing the operation of a vapor recovery system within a fuel dispensing device. The system utilizes strategically placed sensors within the fuel dispensing device to gather data pertaining to each pump and hose combination for that fuel dispensing device. The gathered data is forwarded to an internal digital controller processing device where calculations are performed and results are compared to baseline results stored in memory within the digital controller. Anomalous results are displayed and/or printed. The system operates in both automatic and manual diagnostic modes. The automatic diagnostic mode runs continuously without interfering with the normal operation of the fuel dispensing device.

Vapor recovery diagnostic testing system

The present invention provides a fuel delivery system capable of controlling a fuel dispenser's vapor recovery system based on the absence or presence of an on-board vapor recovery system on the vehicle. This system includes a fuel dispenser having a vapor recovery system, a controller capable of controlling the vapor recovery system, a receiver and an antenna operating in conjunction with the receiver to receive a signal emitted from a transponder on a vehicle indicative of the absence or presence of an on-board vapor recovery system, in addition to a type of vehicle tank or characteristic thereof. When the controller determines from the transponder signal information relating to on-board vapor recovery and/or tank characteristics, the controller will control its vapor recovery system accordingly.

Transponder communication of ORVR presence

A method for monitoring the operation of a vacuum assist vapor recovery system used in conjunction with the fueling of ORVR and non-ORVR equipped vehicles including establishing an expected number of ORVR fueling operations for a fuel dispenser during a defined interval; counting the actual number of ORVR fueling operations during said defined interval; comparing the actual number of fueling operations to the expected number of fueling operations; and permitting fueling operations to continue if the actual number is substantially equal to the expected number.

Vapor recovery diagnostics

The present invention provides pre-transaction estimates of the amount of fuel required to fill a vehicle's tank along with the estimated total cost of filling the vehicle's tank. The invention includes a vehicle-mounted transponder operatively associated with a vehicle control system or, at a minimum, the vehicle's fuel tank in a manner wherein the transponder is able to receive or determine information relating to fuel tank ullage. The ullage information may include the amount of fuel required to fill the tank, tank size and/or the quantity of fuel remaining in the tank. An interrogator at the fuel dispenser will interrogate the transponder and receive the available ullage information from the vehicle. An associated control system will evaluate the ullage information to determine the amount of fuel required to fill the vehicle and, optionally, calculate the total cost to be incurred if the vehicle is filled. The control system may be associated with a fuel grade selector adapted to provide the control system with information to determine the type and cost of the fuel to be used to fill the vehicle. Optionally, the transponder may include information indicative of the desired grade of fuel.

Providing transaction estimates in a fueling and retail system

An apparatus for detecting a vehicle having a vapor recovery system having a fuel dispenser configured to deliver fuel to a fuel tank of a vehicle, a vapor recovery system operatively associated with the fuel dispenser having a vapor path for removing fuel vapor expelled from the fuel tank of the vehicle during a fueling operation, and a hydrocarbon vapor sensor associated with the vapor path for sensing the fuel vapors in the vapor path, wherein when the vapor sensor does not sense fuel vapor during the fueling operation, the fuel dispenser determines the vehicle contains an onboard vapor recovery system. Once a vehicle having an onboard vapor recovery system is detected, the vapor recovery system is either shut off or adjusted during the fueling operation to minimize fugitive emissions.

Onboard vapor recovery detection using pressure sensing means

The invention provides a fuel dispenser for a dispensing system having a receiver capable of receiving fueling parameters transmitted from the vehicle. The fueling parameters relate to information about tank size, ullage, maximum allowed fueling rates and maximum fueling rates as a function of ullage, among others. Based on these fueling parameters, the fuel dispenser controls the fueling operation to optimize fuel delivery and minimize fuel spillage. Control of the fueling operation may vary from simply adjusting the delivery rate to a maximum allowed by the vehicle to defining a fueling schedule for the entire fueling operation wherein the fueling schedule defines a fueling process which varies flow rates throughout the fueling operation as necessary to optimize fueling. Additionally, the dispenser may continuously adjust the maximum fueling rate throughout the fueling operation based upon a fueling parameter defining the maximum fueling rate as a function of ullage. The dispenser may also control the fueling operation based on fueling parameters received from the vehicle in combination with fueling regulations mandated by various regulatory bodies. In such embodiments, the dispenser may optimize the fueling operation while abiding by both vehicular and regulatory limitations, such as maximum allowable delivery rates and predefined average fuel rates for all or various portions of the fueling operation.

Precision fuel dispenser

The present invention provides a fuel dispenser system capable of receiving a signal from a vehicle transponder. Upon receiving the transponder's signal, the dispenser determines the proximity of the vehicle relative to the dispenser, and preferably, a particular fueling position associated with that dispenser. Proximity is determined by measuring one or more characteristics of the signal received at an antenna associated with the dispenser. Generally, the strength or magnitude of the signal received at the antenna is the characteristic used to determine vehicle proximity. Multiple directionally sensitive antennas are used to correlate a vehicle at a unique fueling position. The controller is configured to receive a signal from the transponder indicative of the presence of an ORVR system on the vehicle. Depending on the sophistication of the communication link between the transponder and dispenser, the dispenser will control its vapor recovery system accordingly. If an ORVR equipped vehicle is detected, the dispenser may deactivate the dispenser's vapor recovery system or modify the vapor recovery system performance to maximize vapor recovery or retrieve a sufficient amount of air to reduce breathing of the underground storage tank.
