A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.

A handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter and to modify the functionality of buttons that control scrolling on the display. The control circuitry inverts the orientation of the visual output based on a command provided to the control circuitry by a user or by a position sensor.

A nozzle for dispensing fluid includes a nozzle stem that controls the flow of fluid out of a dispensing end of the nozzle. The nozzle stem includes an overmolded stem tip on a reduced diameter portion of the nozzle stem. The overmolded stem tip is formed from a compliant material and includes a sealing portion and a tip cone extending from the sealing portion.

A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

A fuel dispensing system includes a fuel tank, a pump that pumps fuel from the fuel tank, and a fuel sentry controlling pumping of the fuel from the fuel tank. The fuel sentry includes a processor, storage storing configuration data, a communication module, and memory operatively coupled to the processor, the storage, and the communication module. The memory includes instructions that, when executed by the processor, cause the processor to: receive, from an external device and via the communication module, a request to perform a fuel dispensing operation from the at least one fuel tank, determine, based on the configuration data stored in the storage, whether a user of the external device is authorized to perform the fuel dispensing operation from the at least one fuel tank, and in response to determining that that user is authorized to perform the fuel dispensing operation from the at least one fuel tank, transmit power to the pump from a power source to allow the user to pump fuel.

A fuel dispenser comprises a fuel nozzle configured to be connected to a vehicle fuel system. Fuel piping configured to transfer fuel from at least one fuel storage tank associated with the fuel dispenser through the fuel nozzle into the vehicle fuel system is also provided. A flow control valve and a flow measurement device are located along the fuel piping, the flow measurement device having a housing defining a flow path therethrough. The flow measurement device includes a first exciter for producing a first wave in fuel moving along the flow path. A second exciter produces a second wave in the fuel which passes through the first wave, wherein the second wave has a higher frequency than the first wave. At least one sensor is spaced apart from the first exciter and the second exciter, the at least one sensor being configured to detect at least one measurable characteristic of the second wave from which flow rate can be derived.
