    • An airflow measuring device includes a sensing portion provided in a bypass passage, which perpendicularly deflects part of air from a main passage to therethrough bypass the part of air. The sensing portion includes a heating resistor energized and dissipate heat to airflow. The sensing portion is configured to measure airflow in the bypass passage based on the heat radiation. The sensing portion further includes a pair of support members erected in the bypass passage to support the heating resistor. The heating resistor of the sensing portion is inclined at a first inclination angle with respect to a direction, which is perpendicular to a flow direction of air in the bypass passage. The heating resistor is inclined toward downstream at an outer streamline of the airflow in the bypass passage.

    • In a thermal-type air flow measuring apparatus, a heater is set to a reference temperature which is a predetermined temperature higher than an intake air temperature detector. A flow amount detector is disposed at an upstream side of the heater with respect to a forward direction of an intake air flow. The heater is turned at a plurality of points in a direction perpendicular to the forward direction of the intake air flow and has a predetermined width in the intake air flow direction so that heat transfers less in the intake air flow direction in the heater. If the intake air flow direction reverses, the temperature distribution in the heater also reverses. As a result, an intake air amount varying in response to the air flow direction is detected by comparing the temperature of the flow amount detector with the reference temperature.
    • 在热式气流测量装置中,将加热器设定为比进气温度检测器高的规定温度的基准温度。 流量检测器相对于进气流的前方设置在加热器的上游侧。 加热器在垂直于进气流动方向的方向上的多个点处转动,并且在进气流动方向上具有预定的宽度,使得加热器中的进气流动方向上的热量传递较少。 如果进气流动方向反转,则加热器中的温度分布也反转。 结果,通过将流量检测器的温度与参考温度进行比较来检测响应于空气流动方向而变化的进气量。

    • A flow measuring device includes a flow rate detecting part, an analog/digital conversion part, and a signal processing part. The flow rate detecting part detects a flow rate of air flowing through the passage, and outputs a flow voltage signal, which is a voltage in accordance with the flow rate. The analog/digital conversion part converts the flow voltage signal from the flow rate detecting part into digital data, which is flow digital data. The signal processing part performs calculation processing upon the flow digital data, which includes averaging of a predetermined number of consecutive pieces of the flow digital data, and outputs the averaged flow digital data as a flow rate signal. The predetermined number is equal to or larger than two.

    • 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。
