利用流体与固体间的热传递或加热流体的移动,由测量热的传递、热的转移(即测温度变化)来求得流量、流速的流量计称为热式流量计。其中,在测量流速时采用热线或热膜与热线流速计的是热线式流量计。只要流量测量原理相同,即使用热敏电阻、热细管来代替热线作传感器,也是热线式流量计。但是,若流量测量原理不同,即使用热线那样的自己加热 The use of heat transfer between the fluid and the solid or the movement of the heated fluid, measured by the transfer of heat, heat transfer (ie temperature changes) to obtain the flow rate, flow rate of the flow meter called the thermal flow meter. Among them, the use of hot wire or hot film and hot wire flow meter in the measurement of flow rate is a hot wire flow meter. As long as the flow measurement principle is the same, even the use of thermistors, thermocouples instead of hot wire as a sensor, but also hot-wire flowmeter. However, if the flow measurement principle is different, even if the use of hotline heating itself
