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 cartridge loader includes a lever arm, a hinge axle and a cam centered on the hinge axle, and a housing for receiving a cartridge, the housing having a first end and a second end, the first end adapted to connect to an appliance, and the second end adapted to allow the lever arm to open and close, the housing having an aperture exposing an interior of the housing, the aperture shaped to receive the cartridge and the lever arm, wherein the cam is adapted to assist in seating the cartridge in the housing when the lever arm is closed, and ejecting the cartridge when the lever arm is opened.

The design and structure of an integrated MEMS mass flow meter with a conventional pressure regulator for fuel gas cylinder enabled with wireless data communication is exhibited in this disclosure. The battery-powered MEMS mass flow meter integrated with a pressure sensor, a temperature sensor and a Bluetooth as well as one long-distance communication devices is packed by the conventional fuel gas cylinder mechanical pressure regulator to form a new integrated apparatus. Such an apparatus can digitize the fuel gas consumption supplied by a cylinder to provide such consumption information to the fuel gas cylinder suppliers or the third-party service providers, and will also timely stream the cylinder status such as leakage and location data which will significantly improve the efficiency of fuel gas usage, control, and its supply logistics.

A sensor assembly is positioned on an exterior of a tank to measure a fluid level within the tank. The tank is modified to include a surface feature and the sensor assembly is slotted within that surface feature. The sensor assembly includes a sensor device and a control circuit configured to drive the sensor device and evaluate readings to determine the fluid level. The sensor assembly further includes a communications interface to enable communication with a management system via a communications network. The management system can store information (e.g. fill status) related to the tank and additionally communicate with vendors or end users to coordinate resupply.

A regulating valve device for a fluid cylinder includes a shut off valve having a ball tappet that actuates the shut off valve. A lever has a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly and actuate the shut off valve. The lever is rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position is intermediate of the first and second valve closed positions. A pressure or flow regulating valve is downstream of the shut off valve. A handwheel is operatively connected to the pressure or flow regulating valve to adjust an outlet pressure of the pressure or flow regulating valve. The handwheel has an axis of operation that is offset from a longitudinal axis of the fluid cylinder by an acute angle.

A pressure regulator for controlling the flow of gas from a high pressure source to a low pressure device and regulating a pressure to the low pressure device includes a body having a high pressure inlet and a regulated pressure outlet. The body has a series of passages and bores including first and second regulator valve assembly bores and first and second fill valve assembly bores. The first and second regulator valve assembly bores are disposed on opposing sides of one of the passages and the first and second fill valve assembly bores are disposed on opposing sides of one of the passages. A regulator valve assembly includes a seal, a regulator valve piston, a biasing member and an adjusting plug positioned in the first regulator valve assembly bore, and a seal, a seat, a ball, a spring and a plug positioned in the second regulator valve assembly.
