    • A thermal gas-flow measuring instrument has a first heating resistor placed in the gas to be measured. A temperature sensing resistor is positioned upstream or downstream of the first heating resistor and generates signals relating to the flow rate. Between the first heating resistor and the support for supporting the first heating resistor is a second heating resistor that is electrically insulated from the first heating resistor. The second heating resistor suppresses the heat being transferred from the first heating resistor to the support. A control circuit controls the temperatures of the first heating resistor and the second heating resistor so that the operational temperature range of the second heating resistor or the temperature range at the joint section between the first heating resistor and the second heating resistor is at or above the temperature at which water droplets evaporates to disappear by film boiling.
    • 热气流量测仪具有放置在被测气体中的第一加热电阻。 温度感测电阻器位于第一加热电阻器的上游或下游,并产生与流量有关的信号。 在第一加热电阻器和用于支撑第一加热电阻器的支撑件之间是与第一加热电阻器电绝缘的第二加热电阻器。 第二加热电阻器抑制从第一加热电阻器传递到支架的热量。 控制电路控制第一加热电阻器和第二加热电阻器的温度,使得第二加热电阻器的工作温度范围或第一加热电阻器和第二加热电阻器之间的接合部分处的温度范围在等于或高于 水滴蒸发的温度通过薄膜沸腾消失。
