    摘要: A heating resistor flow rate measuring instrument, having a heating resistor and a thermally sensitive resistor disposed in a sub-passage of a main passage. The heating resistor is disposed in a portion of the sub-passage which has an upstream-side opening substantially perpendicular to the forward direction of a fluid flow and a downstream-side opening substantially parallel to the reverse flaw direction, and the thermally sensitive resistor is disposed in a second sub-passage portion having an upstream-side opening substantially parallel to the forward flow direction and a downstream-side opening substantially perpendicular to the reverse flow direction. Based on changes in resistor temperatures when the flow direction reverses, a precise flow rate may be determined even when a pulsation occurs in the fluid, as both a plus effect caused by a backward flow is eliminated and a value corresponding to the backward flow may be subtracted to obtain accurate flow information.
