Flow measurement sensor

Abstract

To provide a flow measurement sensor which accurately outputs signals even when pulsation flow is generated at high engine speed and also when pulsation flow accompanying reverse flow is generated. In a flow measurement sensor comprising a flow measurement element which has a heater resistance pattern on one side of a plate-shaped member, and a bypass passage in which the flow measurement element is disposed, a first outlet through which fluid flowing along the surface of said flow measurement element flows out, and a second outlet through which fluid flowing along the back side of said flow measurement element flows out are provided, and said second outlet is positioned at a different location from said first outlet.
