THERMAL MASS FLOW METER AND THE GAS-IDENTIFICATION METHOD

摘要

the object of the invention is a thermal mass flow meter and method for identification of gas.a thermal mass flow meter according to this invention is indicated that contains at least two thermal flow sensors with different structural parameters and / or different operation parameters, and the identification of the capacity of gas flowing through the thermal mass flow meter with the use of methods e identification of gas in this invention.identification method of gas indicated that the measured mass flow for different types of gas determined on the basis of the output signals and the measuring znau010dilnic at least two thermal flow sensor, the measured mass flow is used as the input of the identification algorithm type of gas, the gas and the gas is identified.which is the optimal solution in the kriterijske functions.
