熱線素子に直列接続された可変抵抗器とから成る
ことを特徴とする熱線流量計。 A resistor whose resistance value changes depending on the temperature and a hot wire element whose resistance value changes depending on the temperature and which generates self-heating due to the flow of current are placed on each side between the input terminals of the bridge in the flow of the measuring fluid. In a hot-wire flowmeter that detects the flow rate of the fluid based on the voltage difference between the output terminals of the bridge, one side between the input terminals of the bridge includes the hot-wire element and a variable resistor connected in series to the hot-wire element. A hot wire flow meter characterized by comprising a vessel.
