ABSTRACT:
The flow meter is equipped with first and second flow paths, provided in parallel and through which flows fluid having flowed through and being diverted from a main flow path, the flow diversion ratio among the first and second flow paths changing passively in accordance with the flow rate of fluid through the main flow path, and a flow rate sensor provided on at least one of the first and second flow paths. The first and second flow paths are formed, for example, as flow paths having different flow path cross-sectional areas, or alternatively are formed from mesh elements provided with mesh-free areas on a portion thereof. Alternatively, one of the either the first or second flow path is realized with a paddle mechanism incorporated therein.
