Abstract
A split-flow-type flowmeter includes a detection element disposed to face a flow path thereof and a venturi structure formed within a flow path in the vicinity of the detection element and adapted to throttle a flow directed toward the detection element to thereby reduce disturbance of the flow. The venturi structure is disposed in opposition to the detection element within the flow path and includes a protrusion protruding toward the detection element within the flow path of the split-flow-type flowmeter.
