A real time additive processing system for crude oil or refined fuel products is coupled to a fuel transport line that transfers fuel from one storage tank to another storage tank. The fuel additive processing system includes a fuel additive storage tank coupled to a liquid conduit having a liquid pump with a speed/stroke controller that regulates the liquid pump. The liquid conduit is coupled to the fuel transport line at a fuel additive injection nozzle. The fuel additive processing system also includes a flow rate transmitter and a chemical or physical property analyzer coupled to the fuel transport line downstream of the additive injection nozzle. The flow rate transmitter transmits the flow rate of the fuel passing through the fuel transport line. The fuel additive processing system includes a flow controller that communicates with the liquid pump speed/stroke controller, flow rate transmitter and chemical or physical property analyzer.

A fuel dispenser comprising fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle. The fuel flow piping further has a filter manifold for mounting a fuel filter thereon. A plurality of fuel handling components are disposed along the fuel flow piping. A sensor device is mounted to the filter manifold, the sensor device having at least one sensor operative to detect a sensed condition related to the fuel dispenser. The sensor device further comprises electronics to transmit a signal related to the sensed condition.

In some embodiments, an electronic fuel management control and accounting system may include: a server having a management logic in a memory and executable by a processor; a client device having an interface logic in a memory and executable by a processor; and a dispenser control device communicatively coupled to a material providing system to control dispensing of a material from the material providing system. A dispensing logic may be stored in a memory of the dispenser control device and executable by a processor of the dispenser control device. The dispensing logic may communicate with the management logic of the server via the interface logic of the client device thereby allowing the management logic to control dispensing of the material from the material providing system. The system may enable any number of client devices, such as cell phones, to instantly provide access to the material providing system.
