ABSTRACT:
A flow rate sensor is provided. This sensor includes flow rate detecting elements and a plurality of separate circular support members. The circular support members are arranged concentrically within a passage each having a different diameter and support the flow rate detecting elements respectively so as to cover the entire stream area of a diameter section of the passage. Thus, the flow rate sensor may precisely detect the flow rate of a fluid flowing within the passage regardless of instability in the flow distribution of the fluid.
