る熱線式流量計において、被計測流体の通路を２
つに分離し、前記流量を測定する基準抵抗を一方
の通路に、また温度依存抵抗を他の通路に別々に
配置したことを特徴とする熱線式空気流量計。 In a hot-wire flowmeter that consists of a reference resistance and a temperature-dependent resistance that measure the flow rate, there are two paths for the fluid to be measured.
A hot wire air flowmeter characterized in that a reference resistor for measuring the flow rate is separately arranged in one passage, and a temperature dependent resistor is separately arranged in another passage.
