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.

Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

A fleet refueling silo tank system gravity feeds fuel through hoses to fleet units without requiring pressurizing pumps. A specialized valve at the fleet unit fuel tank prevents vapor escape and admits fuel at low, gravity-feed pressures. The valve includes a valve body with an upper end and a lower end, the upper end adapted to engage a cap which affixes the valve body to the fuel tank fill mouth. Below the cap, a fuel cut-off plunger and seat selectively interrupt fuel flow through the mouth by responding to a buoyant float extending coaxially beneath the valve body and into the fuel tank. Linkage coupled to the plunger extends through the valve body to the float, and roller bearings within the valve body engage a shaft extending from the float coaxially into the lower end of the valve body.

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 fuel distribution system includes a fuel intake in communication with at least one fuel source that delivers a fuel through a fuel path. A filtering mechanism is positioned within the fuel path. A surge tank operates to maintain a minimum fluid pressure within the fuel path. A fuel manifold selectively delivers the fuel to a plurality of external fuel couplings. A flow meter monitors a flow of the fuel through the fuel manifold. The plurality of external fuel couplings are configured to contemporaneously deliver the fuel at a consistent flow rate.

An apparatus, including a monitor system including a microphone, first power supply; and transmitter which transmits a first sound indicative of a normal flow of a fluid into a tank and a second sound indicative of a need to cease the flow of the fluid; an attachment device, wherein the monitor system or microphone is attached to the attachment device, and the attachment device is attached to, or attached to an object in a vicinity of, a ventilation pipe; and a receiver system which is headset, earpiece, wearable device, or handheld device, which includes a housing; receiver which receives the first sound or second sound; second power supply; and speaker. The speaker outputs the first audio output indicative of the normal flow of the fluid into the tank and outputs the second audible sound indicative of the need to cease the flow of the fluid.

A hydrogen gas supply system comprises a storing unit that stores hydrogen, a communication unit that receives at least either of burden information indicative of an environmental burden exerted during manufacturing of hydrogen externally received by the storing unit and quality information indicative of quality with respect to the hydrogen externally received by the storing unit, a user interface unit that provides an output in accordance with the at least either of the burden information and the quality information with respect to the hydrogen supplied from the storing unit to the user, and a controller that controls the user interface unit based on an amount of the hydrogen received by the storing unit and the at least either of the burden information and the quality information, which is received by the communication unit.

System, methods, and other embodiments described herein relate to controlling a fuel dispenser. In one embodiment, a method of controlling a fuel dispenser includes broadcasting a pairing signal to a vehicle, receiving, from the vehicle, a confirmation signal confirming completion of a pairing process between the fuel dispenser and the vehicle, transmitting, subsequent to the confirmation signal, a disable signal to the vehicle in response to data from one or more proximity sensors indicating that the vehicle is within a threshold range and a determination that the vehicle is refueling, and transmitting an enable signal to the vehicle in response to a determination that the vehicle is no longer refueling. The disable signal disables a moving capability of the vehicle, and the enable signal restores the moving capability of the vehicle.

Liquid dispenser and method for operating such a liquid dispenser, such as a dispenser for tinting pastes. The dispenser comprises at least one liquid container and at least one reciprocating pump. First, a suction stroke is carried out at a set pump speed. After the suction stroke, the pump is closed off. Then, a pressure stroke is started while the pump is closed.
