    • According to a flow measuring device, first ranges formed by a first plurality of resistors form a single continuous value range on a flow direction coordinate axis. Thus, the first plurality of resistors is limited from being thermally insulated from one another in the flow direction, and thereby detectivity is improved. Also, second ranges formed by a second plurality of resistors form an other single continuous value range on a longitudinal direction coordinate axis. The other continuous value range includes a position that corresponds to a half length of a heating element in a longitudinal direction. As a result, detection difference is obtained at the position, at which a temperature is most optimally detected, and thereby detectivity is further improved.
    • 根据流量测量装置,由第一多个电阻器形成的第一范围在流动方向坐标轴上形成单个连续值范围。 因此,第一多个电阻器被限制为在流动方向上彼此热绝缘,从而提高了检测性。 此外,由第二多个电阻器形成的第二范围在纵向坐标轴上形成另一个单个连续值范围。 另一连续值范围包括对应于加热元件在纵向上的半长度的位置。 结果,在最佳检测温度的位置处获得检测差异,从而进一步提高检测性。
