METHOD OF OBTAINING INFORMATION FEATURES FOR ELECTRONIC APPARATUS FOR MEASURING GAS FLOW AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G01F1/22 

FIELD: physics.

SUBSTANCE: method of obtaining information features for electronic apparatus for measuring quantitative values of gas consumed based on using physical, mechanical, aerodynamic and structural properties of a probing sample of material (turbine) known a priori, where the said sample is put into a vertical cylindrical measuring pipe with a coaxially arranged cone inside, and with a variable volume graduated with electronic markers, and with electrical capacitor plates on its outer surface connected to an electronic circuit which, in their functional combination when the analysed stream of gas with variable quantitative, physical and chemical properties passes through them, provide formation of several groups of unitary electric pulse signals, quantitative values in which and quantitative ratios of which characterise the dynamics of vertical movement and rotational speed of the probing sample of the material (turbine) in the analysed gas medium, size of the cross sectional area of the passage opening, volume of the measuring cylinder occupied by the gas at the given flow rate and temperature which, for electronic apparatus for measuring gas flow, is a set of information features for calculating the value of pressure lost at the given flow rate, value of the changed mass of the turbine, level of lost or acquired sensitivity of the measurement apparatus, the value of the changed sensitivity threshold and quantitative value of the consumed gas reduced to standard conditions used in fiscal measurement for mutual settlements.

EFFECT: design of a universal method of obtaining information features for measuring volume and quantitative values of consumed gas and design of cheap, high-precision, simple, reliable, safe to use and service electronic apparatus for measuring gas flow based on the said method.
