A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

A system provides a level detector with a multi-axis magnetometer sensor that senses movement of a magnet connected to a float within a vessel. A temperature sensor may assist in compensating for changes to the magnetic field due to ambient temperature. Output from the sensor is provided to a local data processing unit which provides level data to a local display. The local data processing unit sends data through a communications port to a remote system which can track level remotely as well as assimilate and uniquely characterize data from other vessels to provide more accurate level measurement by the local processing unit.

A tank valve system comprises a main valve body, an overfill protection device (OPD), a gauge drive apparatus and a fuel level indicator. The OPD and gauge drive apparatus are configured to both be inserted through a narrow neck of a fuel storage tank prior to connecting the valve body to the neck. The valve body includes a primary fuel channel and a shuttle interface channel. The OPD includes an overfill float driving an overfill shutoff valve for controlling fluid flow from the primary channel into the tank. The gauge drive apparatus includes a gauge float, a shuttle, and an elongated extension body. The gauge float is movable with respect to the extension body between an uppermost position and a lowermost position, thereby driving the shuttle. The shuttle has a gauge actuation portion transportable within the shuttle interface channel to thereby actuate the fuel level indicator.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

A system for an air regulated controller. In one embodiment, a solar powered air regulated controller is disclosed. This allows the tanks to be pneumatically controlled via air rather than wet gas. The result is significant emissions reduction. Additionally, as less wet gas is used for venting, more is directed to the downstream sales line.

An assembly is for filling a gas tank for a combustion engine from a gas-filled storage bottle via a filling device arranged between the tank and the storage bottle. The tank has at least one fill valve for liquefied gas, a pressure relief valve for gas in the gaseous state, and an extraction valve for liquefied gas. The filling device has a gas connection for the storage bottle and has a fill connection for the fill valve. For filling the tank, the fill valve is connected via the filling device to the storage bottle, such that, when the fill valve is open, liquefied gas flows from the storage bottle via the fill valve into the tank. During the inflow of liquefied gas, the pressure relief valve of the tank is at least intermittently open. A filling level gauge is provided for indicating a predefined filling level in the tank.

The present invention relates to a liquid gas level measuring system for use in a liquid gas tank and designed to cooperate with a float level gauge head mounted on the gas tank and made of magnetically inert material. The system comprises a dial module 1 attachable to the float level gauge head and a sensor module 2 releasably connected to the dial module 1. The dial module 1 is provided with at least one directing dial magnet 103 magnetically coupled with a drive magnet of the float level gauge. The sensor module includes a Hall effect sensor, a battery 204 and a radio module with an antenna 205, allowing wireless measurement data transmission to a remote location.

A method of distributing liquefied petroleum gas is described. The method comprises receiving payment for a predetermined amount of liquefied petroleum gas, transmitting an instruction to a valve to distribute liquefied petroleum gas monitoring, by a metering device, an amount of liquefied petroleum gas distributed determining, by the metering device, that the amount of distributed liquefied petroleum gas has reached a threshold amount, wherein the threshold amount is based, at least in part, on the predetermined amount, and responsive to determining that the amount of distributed liquefied petroleum gas has reached the threshold amount, transmitting an instruction to the valve to cease distribution of the liquefied petroleum gas.
