摘要： A flow meter for measuring a flow rate of fluid includes a body providing a main passage through which the fluid flows. A plurality of support elements connect an inner wall surface of the body and a central element so as to support the central element substantially at the center of the main passage. An introducing port opens to the central element for introducing a part of the fluid flowing through the main passage. A branch passage is formed within the central element, through which such part of the fluid flows. A sensor is disposed within the branch passage for measuring a flow rate within the branch passage. An outlet opens to a portion of the central element located at upperstream of the downstream ends of the support elements for returning the fluid flowing through the branch passages to the main passage.

摘要： An air flow meter has a cylindrical housing to be coupled to an intake air conduit of a vehicle in a way that a main passage is formed within said housing. An egg-shaped member has a bypass passage formed therein is supported by a plurality of supporting members in a center of the main passage. A flow rate detecting resistance is provided in the bypass passage. There are two throttling portions formed within the cylindrical housing. A downstream throttling portion, which is provided near an outlet of the bypass passage, throttles a flow of air in the main passage near the outlet of the bypass passage so as to cause air in the main passage to be introduced into the inlet of bypass passage by a pressure difference caused thereby. An upstream throttling portion, which is provided upstream of the downstream throttling portion, throttles a flow of air in the main passage so that the flow of air in the main passage is equalized.

摘要： A central member of a sensor unit is inserted through a sensor unit mounting hole of a cylindrical body having a main passage and the sensor unit is assembled on the cylindrical body. The sensor unit comprises the central member which is provided at the center of the main passage and has internally a bypass passage, a flow sensor provided in the bypass passage, a rib which supports the central member, a mounting section which secures the rib to the cylindrical body, an electronic circuit assembled on the rib, and a connector section retaining terminals being connected electrically to the electronic circuit section. Positioning, mounting and securing of the flow sensor can be made simultaneously by a simple process to insert the sensor sensor unit through the hole. Turbulence, eccentricity and others in the upstream air are reduced so that the flow rate of a highly rectified fluid can be measured.

摘要： An air flow meter disposed in an intake pipe has a bypass member having a U-shaped bypass passage, into which part of air flowing through the intake pipe is introduced. An outflow port disposed at a downstream air side of the bypass passage is surrounded at its three sides by opposing surfaces of a pair of side walls and a wall surface of a partition wall disposed at “an upstream air side of the outflow port”. Further, the outflow port is opened in an air flow direction in the bypass passage and in an air flow direction in the air flow passage. Therefore, air flowing through the bypass passage is partially discharged into the air flow passage through the outflow port gradually before joining main air flow in the air flow passage, thereby restricting decrease in air flow velocity and occurrence of turbulence in the bypass passage.
