る熱線式流量計。A hot wire disposed in the fluid passage and a temperature compensation resistor disposed in the same atmosphere as the hot wire are fixedly supported on the fluid passage wall, and a bridge circuit including these resistors is configured, and the bridge circuit is In a hot wire flowmeter that controls the current supplied to the bridge circuit so as to balance it and measures the flow rate of fluid from the value of the supplied current, the fluid passage wall is connected to the hot wire to constitute the bridge circuit. 1. A hot wire flowmeter characterized in that a lead wire that is affected by temperature is constituted by a resistance wire having a temperature coefficient that cancels the unbalance of the bridge circuit due to the influence of the fluid passage wall temperature of the temperature compensation resistor.
