Abstract
A method for determining at least one gas parameter, of a flowing gas, by means of a flow meter, comprising a measurement section having a heating element and at least three temperature sensors, over which the gas is fed, at least one first temperature sensor being arranged upstream of the heating element, at least one second temperature sensor being arranged in the region of the heating element, and at least one third temperature sensor being arranged downstream of the heating element, wherein a calculation unit determines the at least one gas parameter as a function of the temperature measurement values at the first, second and third temperature sensors, and/or at least two separate gas parameters as a function of the temperature measurement values of individual different temperature sensors and/or the combinations of temperature measurement values of different temperature sensors.
