FIELD: measuring equipment.
SUBSTANCE: disclosed is a method and a measuring device for determining gas quality parameters, in which gas or gas mixture flows both through ultrasonic flow meter (4), and through microthermal sensor (7), and the first one is used to determine sound velocity and flow, and with the help of the second one, heat conductivity and heat capacity of gas or gas mixture are determined. Sound velocity, heat conductivity and heat capacity are used to correlate specific parameters for gas properties.
EFFECT: possibility of accurate determination of gas quality parameters in real time.
