We present a novel potentially gas-independent thermal flow sensor chip that contains three two-wire calorimetric flow sensors to measure the flow profile and flow direction inside a tube, and a single-wire flow-independent thermal conductivity sensor which detects the type of the gas through a simple DC voltage measurement. All wires have the same dimensions of 2000 µm in length, 5 µm in width and 1.2 µm in thickness. Four different gases Ar, N 2 , Ne and He were used for the thermal conductivity measurement and the measured output voltage corresponds very well with a theoretical model.
