Abstract :
In this contribution, we present a novel design and excitation procedure for a thermal flow sensor to simultaneously determine thermal conductivity and flow rate of gas in a channel. For the first time, these two parameters can be detected by using a time-independent (DC) excitation mode. Theoretical and experimental results are discussed in order to specify possible application fields.
