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.

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 filling station comprises a filling device for an automated filling of a gas bottle inserted in the filling station and a filling device for refueling a motor vehicle, wherein the filling device for an automated filling of a gas bottle inserted in the filling station is arranged adjacent to the filling device for refueling a motor vehicle.

The invention relates to a filling level measuring device for measuring the filling level in a container through the wall thereof by means of ultrasound, having an ultrasonic measuring head, a controller, and a fastening device by means of which the filling level measuring device can be fastened to the container such that the ultrasonic measuring head is pressed against the wall of the container. The invention further relates to a method of operating such a filling level measuring device, wherein a sampling rate is used which is situation-dependent. The invention finally relates to an assembly made up of such a filling level measuring device and at least one spacer which can be attached to the lower edge of a container to be provided with the filling level measuring device.

Provided is a portable cylinder including a tank having an upper portion having a valve port, a mounting collar coupled to the upper portion of the tank, and a handle attached to the mounting collar. The mounting collar has an upwardly extending portion surrounding the valve port and a plurality of circumferentially spaced tabs extending radially outwardly from the upwardly extending portion, wherein a respective gap is formed between adjacent ones of the plurality of circumferentially spaced tabs. The handle includes a shroud portion including a plurality of circumferentially spaced ledges for abutting an underside of a respective one of the plurality of circumferentially spaced tabs, and at least one tab for engaging the mounting collar in one of the gaps, and a handle portion extending from the shroud portion and having one or more areas for grasping the handle.

This application describes methods for responding to a storage vessel leakage event and the implementation of one or more assemblages of components to provide remediation of the leakage event. This application also describes methods of teaching storage vessel leakage remediation for responders and how to use the method of responding to storage vessel leakage event in combination with the one or more assemblages of components.

The present invention relates to a remote propane-monitoring device primarily comprised of a body with a front surface further comprised of a display and at least one button, a retaining clip and a mobile application. In the preferred embodiment, the body is generally rectangular and is made from a rigid, water-resistant/water-proof, weather-resistant plastic. The body further has a clip assembly that allows the device to attach to a propane gauge of a propane tank and a piping/tubing that attaches to the tank. The device is further comprised of an internal pressure gauge that reads the pressure of the propane gas being pushed out from the tank to determine the level of propane gas left in the tank and relay said information to the mobile application.

A metering device for attaching to a container configured to store a fluid, the device including: a valve configured to control the amount of fluid dispensed from the container; a user interface comprising at least one control configured to operate the valve between an open position and a closed position; and a control circuit configured to set a threshold amount of the fluid to be dispensed from the container, where the control circuit is configured to override the user interface and close the valve when the threshold amount of fluid to be dispensed has been reached.

Provided is a foot ring secured to a tank having a collar, The foot ring includes a base having an inner and outer surface, a central portion, and an outer peripheral portion, a plurality of circumferentially spaced deflectable longitudinal lock tabs extending around the base for securing the foot ring to the tank, and a plurality of circumferentially spaced deflectable rotational lock tabs extending around the base for preventing rotational movement of the foot ring relative to the tank. Each of the circumferentially spaced deflectable longitudinal lock tabs have a first projection and a catch extending from the first projection for engaging a flange of the collar, and each of the circumferentially spaced deflectable rotational lock tabs have a second projection configured to be received in a respective notch in the flange.

Disclosed is a gas injection apparatus which measures and displays a gas amount supplied to a radiosonde instrument.

The gas injection apparatus includes: a body which includes an inlet port through which the gas is introduced from the storage tank, a flow passage through which the gas introduced from the inlet port flows, and an outlet port through which the gas passing through the flow passage is discharged; a valve which opens/closes the flow passage, and a flow meter which is installed in the body and is configured to measure and display the flow rate of the gas supplied to the instrument.
