| Zusammenfassung: | A flow sensor has a flow passage 4, a rectifying element such as a plurality of screens 2 or a honeycomb structure 8, arranged in the flow passage, a flow passage reducer 3 for reducing the flow passage behind the rectifying element, and a thermal flow sensor 1 mounted at a location immediately behind the reducer. This structure can largely reduce disturbance in flow to thereby enable highly accurate measurements of a wide range of flow without a low pass filter. |
