<p>A flow rate sensor is provided. This sensor includes a flow rate detecting element (1). The flow rate detecting element (1) is provided within a flow passage (10) so as to expose the flow rate of a medium whether at the center of the passageway or at the inner surfaces of the passage wall. The flow rate detecting element has a plurality of openings (1a) for allowing the medium to pass therethrough without pressure loss. Thus, the flow rate sensor may precisely detect the flow rate of a medium flowing within the passage regardless of insecurity in the flow distribution of the medium.</p> |
