The flow meter has an inlet flow port (4) tangentially formed at a cylindrical measuring housing in plastic injection molding. A sensor is provided at the housing for determining fluid amount flowing through the housing based on rotation of a wheel blower. An outlet flow port is centrally formed at a housing cover, and the inlet flow port encloses a nozzle tube (18) forming a nozzle channel so that a fluid flows through the flow meter in a cyclonic manner, where the tube is inserted into the inlet flow port and opens corresponding to a direction of the inlet flow port. |
