A gas dosing apparatus is provided that includes an inlet configured to receive gas, and a directional control valve connected to the inlet and having a first position and a second position. The gas dosing apparatus also includes a fixed volume reservoir connected to the directional control valve and receiving gas from the inlet, via the directional control valve, while the directional control valve is in the first position. The gas dosing apparatus further includes an outlet connected to the directional control valve and outputting a gas dose received from the fixed volume reservoir, via the directional control valve, while the directional control valve is in the second position.

Gas dosing apparatus with directional control valve

A valve integrated pressure regulator (VIPR) device is provided that includes a gas flow valve arrangement, a shroud and digital gauge display that can be attached or coupled to a gas cylinder, and which can monitor the amount or pressure of the gas in the gas cylinder. Features of the disclosed valve integrated pressure regulator device include an electronic control, electronic alarm and the electronic display that are powered by a battery that may be disposed within the shroud. The battery and/or electronic control are accessible via a removable access panel disposed on the front surface of the shroud.

Valve integrated pressure regulator with shroud and digital display for gas cylinders

A valve integrated pressure regulator (VIPR) device that can be attached to the outlet of a gas cylinder, which can monitor the amount of gas in the cylinder is provided. Features of the disclosed device include an electronic control, electronic alarm and the electronic display that are powered by rechargeable battery that may be disposed within the VIPR shroud or within a removable cylinder base affixed to a bottom of the gas cylinder. Additional functionality and security features may be provided via additional internally disposed sensors and/or wireless or hard-wired communications with one or more auxiliary devices.

Method and apparatus for controlling gas flow from cylinders

A device that can be attached to the outlet of a gas cylinder, which can monitor and display in digital or analog form the pressure of the gas in the cylinder and the interval of time remaining until the amount of gas in the cylinder will reach a predetermined lower threshold at a given flow.
