A method for optimizing purge gas of a flare system includes measuring a flow of flare fluids within a flare system to obtain a measured flow value. The flow of the flare fluids is compared to a target flow to obtain a difference between the flow of the flare fluids and the target flow. A control valve is operated to amend a flow of purge gas and the steps of measuring a flow of flare fluids and comparing the flow of the flare fluids to the target flow are repeated until the flow of the purge gas is within a target range. A value of the flow of purge gas is measured and transmitted wirelessly to a control system.

A cooling circuit for a fuel cell includes at least one channel, a mechanical support, a first sensor, and a second sensor. Each channel is formed in a bipolar plate of the fuel cell, and is adapted to permit a cooling fluid to flow. The first sensor senses a flow rate of the cooling fluid. The second sensor senses an electrical conductivity of the cooling fluid. Both the first sensor and the second sensor are installed on the mechanical support.

A flavouring dispenser for dispensing doses of flavouring is disclosed. The flavouring dispenser comprises a flavouring chamber for containing flavouring; a dosing member having a dosing volume for receiving flavouring from the flavouring chamber, the dosing member defining an opening to the dosing volume through which flavouring is received from the flavouring chamber. A reciprocating member is movable relative to the dosing member between a closed position, at which the opening is isolated from the flavouring chamber by the reciprocating member, to a first open position, at which the opening is partially exposed to the flavouring chamber such that an amount of flavouring may enter into the dosing volume via the opening, and back to the closed position, such that the flavouring may be dispensed by the dosing member. The first open position of the reciprocating member is adjustable such that degree to which the opening is exposed to the flavouring chamber may be changed so as to adjust the amount of flavouring received in the dosing volume.

A dispenser includes a main body having a discharge opening, an open interior configured to receive a supply of granulated product and a discharge spout for dispensing the granulated product therefrom. A loading and dispensing member is constructed with a plurality of spaced apart receiving cavities formed therein, and is movably mounted within the main body.

The present invention controls convergent pressure of a closed space provided with a fluid resistance at high speed while an upstream valve provided on the upstream of the fluid resistance prevents overshooting. A pressure control system is provided with a fluid resistance in a channel forming a closed space and is configured to control pressure of the closed space by controlling an upstream valve provided on the upstream of the fluid resistance. The pressure control system includes a convergent pressure arithmetic unit and a valve controller. The convergent pressure arithmetic unit calculates convergent pressure of the closed space when the upstream valve is fully closed using at least one of upstream pressure and downstream pressure on the fluid resistance in the channel. The valve controller compares the calculated convergent pressure with a predetermined target convergent pressure and fully close the upstream valve based on the result of the comparison.

A method for controlling a filling process, wherein a predetermined filling quantity of a medium is filled into a container, the flow rate of the medium flowing into the container is measured as a time series of measured values for the instantaneous flow rate and a filling quantity already filled is estimated from the time series, wherein at least one current measured value of the time series is corrected on the basis of at least one earlier measured value of an earlier time series of measured values of the flow rate of an earlier filling process.
