Providing a fast response to a process step while allowing a sensor response to remain relatively slow. A mechanical component generates a response to a step change in a physical property and an electrical component generates an analog electrical signal indicative of the response generated by the mechanical component over a period of time. The analog electrical signal is converted into digital values and the digital values are used to indicate the final value of the step change in the physical property before the period of time has elapsed.

A solvent storage and depressurization system is described. The system allows a volume of solvent to be stored and used at low pressure, thereby providing safety benefits and regulatory simplicity. The system includes an external expansion tank that is located outside of an extraction facility and that contains a solvent. The system also includes an internal storage tank that is located inside of the extraction facility and that provides a solvent supply to a solvent user, such as a phytochemical extraction system. The external and internal tanks are separated and connected via a duplex manifold. The manifold allows gas below a first pressure level to pass from the external expansion tank to the internal storage tank, and allows gas above a second pressure level to pass from the internal storage tank back to the external expansion tank, wherein the second pressure level is greater than the first pressure level.

In one example, a portable fuel gas system includes: a portable enclosure; a fuel gas supply manifold; a throttle in fluid communication with the fuel gas supply manifold. The fuel gas supply manifold includes a first pressure zone and a second pressure zone separated from one another by the throttle; and a fuel gas shutoff valve in fluid communication with the fuel gas supply manifold and operative to control a flow of a fuel gas in the fuel gas supply manifold, wherein the fuel gas supply manifold, the throttle, and the fuel gas shutoff valve are disposed within the portable enclosure.

In a gas supply system of one embodiment, if first detection information of a high-pressure sensor exceeds a first threshold value, a gas control ECU causes a pressure adjustment range to overlap a second error range of second detection information of a mid-pressure sensor, the second error range being defined with a second threshold value as a reference point. If the first detection information is less than or equal to the first threshold value, the gas control ECU offsets the pressure adjustment range relative to the second error range defined with the second threshold value as the reference point.

A pressure vessel system has a pressure vessel for storing gaseous fuel, a fuel line, and a total-pressure sensor for measuring a total pressure of the fuel at a position within the fuel line. This makes it possible for various functions, such as the control of power reduction, for example, to be performed more accurately than if only static pressure were being used. The technology disclosed here also relates to an energy supply arrangement having such a pressure vessel system and having an energy converter, such as a fuel cell, for example.

A control conduit for liquid hydrogen offloading is configured to couple a controller of a liquid hydrogen offload system to a liquid hydrogen tanker. The control conduit includes a control line and a gas detector. The control line is configured to transmit a control signal from the controller to the liquid hydrogen tanker. The gas detector is configured to detect hydrogen gas and provide a gas detector signal to the controller. The gas detector is secured to the control line at a predetermined distance from a tanker connection end of the control line.

The present disclosure relates to a valve unit for a fuel supply system which is preferably adapted to supply a fuel cell system with fuel, comprising: at least one temperature detector, at least one pressure detector, and a safety valve integrated into a line section, wherein the safety valve can be adjusted between an open position, in which gas is able to flow through the line section, and a closed position, in which gas is not able to flow through the line section, wherein the temperature detector and the pressure detector are so disposed that they are able to detect a temperature and a pressure of the gas flowing through the line section in a state in which the gas is present at the closed safety valve in such a manner that it exerts pressure. The present disclosure relates further to an on-tank valve which can have all the features described in relation to the valve unit and differs from the valve unit only in that it is able to be mounted directly on a gas pressure tank. The present disclosure relates further to a gas pressure tank system for storing fuel, comprising: at least one gas pressure tank and a valve unit. Finally, the present disclosure relates to a method for detecting a possible leakage in a fuel supply system, and to a valve assembly.
