Abstract
A flow rate and flow velocity measurement device has a divided flow pipe ( ) which is attached so as to be orthogonal to an intake pipe ( ) of an engine, and into which a flow in the intake pipe ( ) is introduced, an inlet plate ( ) which extends in a direction orthogonal to a flow direction in the intake pipe ( ) and forms a U-shape form pipe passage in the divided flow pipe ( ) and a detection element ( ) which is disposed so as to be exposed to a flow in the divided flow pipe ( ) outside the intake pipe ( ) and detects a flow rate and a flow velocity, wherein one end of the inlet plate ( ) protrudes into the intake pipe ( ) while passing a top opening of the divided flow pipe ( ), and the divided flow pipe ( ) has a flow passage structure symmetrical with the detection element ( ) being made a center, so that an equivalent detection element ( ) output is obtained in regard to both cases in which a fluid flows through the intake pipe ( ) in a normal direction and a reverse direction.
