<p>A flow rate measuring system comprises a measuring mechanism (21A) for the radiation coefficient and/or the termal conductivity, a storing device (402) storing a thermal diffusivity calculation equation, a thermal diffusivity calculating portion (305), a flow rate sensor (41A) and a correcting portion (332) correcting a flow rate detection error, where a heater (61A) has produced heat at a plurality of temperature at which the radiation coefficient and/or the thermal conductivity was measured.</p> |
