And the feasibility of the two measurement methods is demonstrated.3 Computer simulation is performed in the situation of air passing by a heating columned thermistor through a round pipeline. The fluid velocity and temperature distributions under different mass flowrate are shown. They reflect the impact the heating thermistor has on the fluid. The velocity distribution on the surface of the heating thermistor is studied and the impact of natural convection is revealed. The lower limit of measurement based on the simulation result is given.
