ABSTRACT:
A secondary flow channel of a flow rate measuring device includes: a guide flow channel in which an upstream side communicates with a guide port serving as a first bifurcation point, and a downstream side serves as a second bifurcation point; a first secondary flow channel in which an upstream side is bifurcated from a guide flow channel at the second bifurcation point and formed to be parallel to a primary flow channel, and a downstream side communicates with a discharge port; a second secondary flow channel in which an upstream side is bifurcated from the guide flow channel at the second bifurcation point and formed to cross the primary flow channel; and a detection flow channel in which an upstream side communicates with a downstream side of the second secondary flow channel, a flow rate detecting element is disposed, and a downstream side communicates with the discharge port.
