The present invention is directed generally to the field carbonated beverage dispensing systems having a replaceable carbon dioxide storage cylinder. Such systems may be embodied in the form of a unitary apparatus including, but not exclusively, on-bench, under-bench or freestanding beverage cooling units. The invention may be embodied in the form of a beverage dispensing unit having a gas input connector configured to make gas tight connection to a gas container configured to hold a gas under pressure and a mass detection device. The gas input connector and mass detection device are arranged such that when a gas container is connected to the gas input connector, the mass detection device is capable of detecting a mass associated with the gas container. The unit may further have a gas container support extending from or about the mass detection device configured to maintain a gas container connected to the gas input connector in a position such that it bears on the mass detection device so as to allow the mass detection device to measure the mass of the gas container and any gas contained therein. Computer-implemented methods for monitoring the level of gas are also provided.

A tank device for a tank liquid comprises a pressure vessel with a first chamber for the tank liquid and second chamber arranged in an interior of the tank. The first and second chamber are closed off with respect to each other and are in operative connection via at least one membrane which separates the first and second chambers and is capable of vibration. The tank device further comprises a controllable element for effecting a pressure surge in the pressure vessel, a pressure sensor for detecting a pressure vibration resulting from the pressure surge and a temperature sensor for measuring a temperature prevailing in the pressure vessel. An evaluation device of the tank device is configured to determine a current gas volume in the pressure vessel from a respectively detected pressure vibration and a measured temperature to thereby calculate the mass of the tank liquid.

An inspection apparatus A for a hydrogen gas dispenser includes a receiving-side gas flowing unit 1 including a receptacle 11 configured to be connected to a nozzle C1 of a hydrogen gas dispenser C and an inspection unit including a rate-of-pressure-rise inspection unit 2 configured to measure a rate of pressure rise of hydrogen gas from the hydrogen gas dispenser C and a dispensed-amount inspection unit 3 configured to measure a dispensed amount of the hydrogen gas. The inspection apparatus A for a hydrogen gas dispenser is capable of measuring a dispensed amount and a rate of pressure rise of the hydrogen gas dispenser.

According to one or more aspects, systems and techniques for hydrogen fueling with integrity checks are provided herein. Communicated parameters measured by on-board sensors of a vehicle may be cross-referenced against calculated parameters measured by sensors of a fueling station. For example, communicated parameters relating to a compressed hydrogen storage system (CHSS) tank of a vehicle to be fueled may be received at different time intervals. Calculated parameters may be calculated based on a mass of hydrogen fuel dispensed by a hydrogen fueling station from a reference point to one of the time intervals and densities of the CHSS tank of the vehicle at respective time intervals. An error may be calculated between the communicated parameters and the calculated parameters. A fueling mode, such as a conservative fueling mode or a non-conservative fueling mode, may be determined based on the calculated error.

The gas supply system of this invention is furnished with a cylinder apparatus having a pneumatic valve that supplies process gas to a process chamber, and a solenoid valve that opens or closes said pneumatic valve by supplying or stopping the flow of valve actuating gas to said pneumatic valve; and a gas supply control apparatus that controls the actuation of the solenoid valve. In addition, said gas supply control apparatus comprises a main controller that controls the actuation of said solenoid valve during normal operation, and a sub-controller that senses an abnormal state of said main controller and if an abnormality is sensed, controls the actuation of said solenoid valve instead of said main controller.

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.

A pressure gauge system for a tank with a variable flow rate that provides a user with an indication of how much usable time is left in a pressurized gas tank given a particular selected flow rate or operational condition and what pressure of gas is left in the tank.

A method for supplying helium to at least one end user is disclosed by feeding helium from at least one container of helium to an end user through at least one supply system, wherein a mass flow meter and a pressure transmitter, in electronic communication with a programmable logic controller measures an amount of helium being supplied to the at least one user, provides the amount to the programmable logic controller which provides a signal to the at least one end user of an amount of helium that remains in the at least one container and the temperature therein.
