A fuel dispensing system includes a fuel tank adapted to contain a quantity of fuel. A fuel dispenser in is fluid communication with the fuel tank via piping. A pump is operative to transfer fuel from the fuel tank to the fuel dispenser. A corrosive detection assembly operative to identify presence of a corrosive substance in the fuel is also provided. The corrosive detection assembly has at least one thermoelectric detector positioned to be in contact with fuel vapor in the fuel dispensing system, the thermoelectric detector producing a detector signal indicating presence of the corrosive substance. Electronics are in electrical communication with the thermoelectric detector, the electronics being operative to interpret the detector signal and produce an output if the corrosive substance is present. The at least one thermoelectric detector may comprises a plurality of thermoelectric detectors at different locations in the fuel dispensing system.

A method for tracking fluid delivery from a storage tank to a vehicle operated by a user includes obtaining a user ID and a vehicle ID from the user. The obtained user ID and vehicle ID are compared to a database of authorized user IDs and vehicle IDs. Fluid is allowed to be dispensed from the storage tank to the vehicle if the obtained user ID and vehicle ID match the authorized IDs and vehicle IDs in the database.

A monitoring and control system (100) for containers (3). The containers (3) respectively have a container opening (5) for supplying and dispensing of stored goods. Each container (3) has a sensor unit (10) which has at least one sensor capturing environmental impacts, one processor evaluating sensor signals (13) and one interface unit (14) which operates in a contact-free manner.

A system determines that a fuel dispensing operation may be anomalous. In response, the system accesses fuel inventory data that indicates fuel levels in a fuel tank during a time period. The system determines a measure amount of fuel that left the fuel tank based on the fuel inventory data. The system determines a calculated amount of dispensed fuel associated with one or more fuel dispensing operations during the time period. The system compares the measured amount of fuel that left the fuel tank with the calculated amount of dispensed fuel. The system determines that the measured amount of fuel that left the fuel tank is more than the calculated amount of dispensed fuel. In response, the system concludes that at least one of the fuel dispensing operations is anomalous and causes the fuel dispensing terminal to stop dispensing fuel.

A fuel dispenser is provided with a nozzle drying function that prevents the refreezing of melted ice buildup upon subsequent uses of the nozzle. The fuel dispenser comprises a housing including a holster. A fuel dispensing nozzle is configured to mate with a holster. A port is configured to direct air into the holster and onto the nozzle. A controller is configured to control flow of the air through the port. The port may be attached to a blower located inside or outside of the dispenser using tubing. Alternatively, the port may be attached to a compressed air assembly. The compressed air assembly may include a pressure regulator configured to control the amount of air produced. A heater may heat the air flowing to the port. A pressure cap including a plurality of openings may be configured to seal the nozzle when the nozzle is mated with the holster.

A system for tracking fuel in a fuel distribution network is provided. The system includes a plurality of tracking devices disposed at a plurality of fuel transport locations including a supplier fuel storage location, a mobile fuel storage location, a stationary fuel storage location and a vehicle fuel location, wherein each tracking device is configured to read in real time the digital tag by receiving a radiation emission spectrum associated with the fuel identification information as the fuel is transported through the plurality of fuel transfer locations. The digital tag includes information about the fuel.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

A multiply-redundant system that protects fueling of rockets, aircraft and other vehicles using Liquefied Natural Gas (LNG) along with an oxidizer such as Liquefied Oxygen. One or more sensors in combination with one or more optional microswitches combine to detect any leaks, fire or explosion hazards quickly locking out further fueling. For different levels of safety, different combinations of sensors can be used.

A fuel analyzer for a fuel dispensing environment is provided including an ultrasonic transmitter configured to transmit an ultrasonic signal through a volume of fuel, an ultrasonic receiver configured to receive the ultrasonic signal, and processing circuitry. The processing circuitry is configured to receive an indication of transmission of the ultrasonic signal from the ultrasonic transmitter, receive an indication of receipt of the ultrasonic signal from the ultrasonic receiver, determine a time of flight of the ultrasonic signal, and determine a fuel purity based on the time of flight of the ultrasonic signal.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.
