Abstract
A Karman vortex flow meter has detection passages located along a fluid flow in a duct. Flow outlets of the detection passages are disposed on an end face of a vortex generation element and flow inlets are disposed upstream from the flow outlets. Heating coils for detecting flow velocity change of a fluid caused by a negative pressure of a Karman vortex are mounted in the detection passages. A flow meter is used that lessens dust accumulation on heating coils, etc., and reliably detects Karman vortexes.
