A mobile fuel monitoring system (MMU) is disclosed. The fuel monitoring system may be skid mounted and is configured to monitor fuel transfers between a fuel source and a vessel, such as a ship. The disclosed MMU is a stand-alone, self-contained unit that can be easily moved from place to place. The MMU is configured to monitor and remotely report custody transfers of fuel performed at any location. Parameters of the fuel transfer operation, such as the amount of fuel transferred, the flow rate, the fuel density, and fuel temperature can be monitored and alarms may be issued if any of the parameters are out of specification. The parameter values may be transmitted to a remote location, for example, via a satellite link.

A fuel dispenser comprises a housing enclosing fluid handling components including a fluid flow meter. The housing has a user interface including a panel display. A control system is in electrical communication with the user interface and is operative to display money and volume information on the panel display during a fueling transaction. A secondary display having digit structure that registers fuel dispensing information is in electrical communication with the control system. The secondary display is configured to not be viewable by a customer during a fueling transaction.

Systems and methods are provided for controlling maintenance of a fuel dispenser. In one exemplary embodiment, a system is provided having a fuel dispenser that includes an electronics module having a data processor, a remote enterprise server in communication with the electronics module, and a remote code processor in communication with the remote enterprise server. The data processor is configured to determine an authorization password based on data characterizing the fuel dispenser, to receive a remote password that is generated by the remote code processor based on the fuel dispenser data, to determine that the remote password matches the authorization password, and to cause the fuel dispenser to enter a maintenance mode.

A fluid delivery system or method for the same may include features or steps for dispensing, via a nozzle, a first fluid from a first fluid storage tank of at least two fluid storage tanks. The fluid storage tanks may be separately fluidly coupled to a manifold via respective fluid supply lines. A fluid delivery line fluidly may couple the nozzle to the manifold. A residual first fluid may remain within the delivery line after the dispensing step. The system or method may further include features or steps for connecting the nozzle to a clearance tank. A clearance outlet line may fluidly couple the clearance tank to the manifold. The system or method may further include features or steps for purging the residual first fluid from the fluid delivery line into the clearance tank and delivering the residual first fluid from the clearance tank to the first fluid storage tank.

Vehicle fuel fill control systems may anticipate vehicle refueling events in order to control the timing of fuel tank depressurization sequences. In a first embodiment, a global positioning system (GPS) is utilized to anticipate the vehicle refueling event prior to initializing the depressurization sequence. In another embodiment, a camera system is utilized to anticipate the refueling event prior to initializing the depressurization sequence. In yet another embodiment, both the GPS and the camera system may be utilized to anticipate the refueling event. By anticipating refueling events, customer wait time for gaining refueling access may be reduced.

The invention relates to a method for monitoring a container treatment installation which has a filling apparatus for filling containers and a closure apparatus for closing containers. The method involves filling a container with a filling material using the filling apparatus and measuring a concentration of a gas in the filling material of the filled container using a measuring device, wherein the filled container is removed in order to measure the concentration upstream of the closure apparatus or the concentration is measured upstream of the closure apparatus. Advantageously, the method allows the low-oxygen filling by the filling apparatus to be able to be monitored in a selective manner.
