Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
Method for measuring gas quantities which flow through an inlet opening (1), characterised in that the gas is passed through a block (2) of binary clack valves which are connected in parallel with maximum passage capacities which differ from one another, whereby the total drop of pressure across the block (2) is maintained at a pre-determined value by continuously detecting deviations from this value with a pressure detector (3) which controls a regulation system (4) with the signals which correspond therewith, which, depending on the signals which are received, opens and/or closes clacks in valves, after which the volume flow is read-off from the position of the valves.
Claim 2
Dependent Claim
108 words
Method for measuring gas quantities which flow through an inlet opening (1), characterised in that the gas is passed through a block (2) of binary clack valves which are connected in parallel with maximum passage capacities which differ from one another, whereby the total drop of pressure across the block (2) is maintained at a pre-determined value by continuously detecting deviations from this value with a pressure detector (3) which controls a regulation system (4) with the signals which correspond therewith, which, depending on the signals which are received, opens and/or closes clacks in valves, after which the volume flow is read-off from the position of the valves.
Claim 3
Dependent Claim
52 words
Method according to claim 1, characterised in that the precision adjustment of the pressure drop for very small quantities of gas is obtained by adjusting the passage capacity of the valve with the smallest maximum passage capacity via a clack which can be continuously adjusted between an open and a closed position.
Claim 4
Dependent Claim
60 words
Method according to claim 1 or 2, characterised in that for determining the weight quantities of a gas which has flown through an opening (1) the temperature of the gas and the pressure of the gas in the supply pipe are determined with the aid of sensors, with the aid of which the details on the volume flow are corrected.
Claim 5
Dependent Claim
17 words
Method according to claim 3, characterised in that the correction is carried out with a micro- processor.
Claim 6
Dependent Claim
37 words
Method according to claim 4, characterised in that for determining the heat content of the quantity of gas which has flown through an opening (1) the micro- processor is adjusted according to the composition of the gas.
Claim 7
Dependent Claim
81 words
Device for the implementation of the method according to claim 1, characterised in that it contains a block (2) of binary adjustable clack valves which are connected in parallel with maximum passage capacities which differ from one another behind the inlet (1), a pressure detector (3) for measuring the differences which occur in the drop of pressure across the block (2), coupled with a system (4) which, controlled by these differences in drop of pressure, adjusts the position of the clacks.
Claim 8
Dependent Claim
36 words
Device according to claim 6, for the implementation of the method according to claim 2, characterised in that the clack of the valve with the smallest maximum passage capacity is continuously adjustable between open and closed.
Claim 9
Dependent Claim
49 words
Device according to claim 6 or 7, for the implementation of the method according to claim 3, characterised in that it is equipped with a temperature sensor and with a pressure sensor in the supply pipe, both coupled with the part of the device which measures the gas quantities.
Claim 10
Dependent Claim
21 words
Device according to claim 8, characterised in that the part of the device which measures the gas quantities is a micro-processor.
