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： A flow meter includes a tubular member having a main passage in which fluid flows. A branch passage member disposed in the main passage has a branch passage in which the fluid flows. A support member connects the branch passage member and a wall of the tubular member, and supports the branch passage member within the main passage. A partition arrangement disposed in the branch passage divides the branch passage into a plurality of sub passages extending along a flow of the fluid. A flow-rate measuring resistor is disposed in a region of the branch passage downstream of the partition arrangement for sensing a rate of a flow of the fluid in the branch passage. A control circuit electrically connected to the flow-rate measuring resistor is operative for calculating a measurement value from an output signal of the flow-rate measuring resistor. An outlet formed in the branch passage member is operative for connecting the branch passage with the main passage to enable the fluid to move from the branch passage into the main passage after the fluid meets the flow-rate measuring resistor. The partition arrangement includes a partition plate. A length of a part of the partition plate, measured along a direction of the fluid flow, depends on a position of the part.

摘要： A bypass passage receives a part of air flowing through a duct. A sub-bypass passage is branched from an intermediate portion of the bypass passage to separate dust contained in air flowing through the duct. A flow rate sensor is located in the sub-bypass passage for detecting the flow rate of air. A first wall surface and a second wall surface of the bypass passage are located upstream from the branch. The first wall surface is located on the side of the branch. The second wall surface is opposed to the first wall surface. Both the first wall surface and the second wall surface are curved to direct airflow to move away from the branch.

摘要： A flow detecting device is provided to a fluid passage through which a main flow of fluid passes. A sensor body has a bypass passage through which a bypass flow passes from the main flow. The bypass passage has a bent portion, which is located midway through the bypass passage, and an outflow passage, which is located downstream of the bent portion. The flow direction of the bypass flow changes at the bent portion toward the outflow passage through the bypass passage. A heating element is arranged in the bypass passage. The heating element generates heat by being supplied with electricity for detecting a flow amount of fluid. The sensor body has a side surface defining an opening through which dynamic pressure caused by counterflow is released to an outside of the outflow passage when fluid causes counterflow in the fluid passage in a direction opposite to a flow direction of the main flow.

摘要： A substrate includes a first surface portion, which covers a heat receiving portion of a radiation member together with a resinous member. The substrate further includes a second surface portion, which is on the outer periphery of the first surface portion. The substrate makes contact with the resinous member via the second surface portion. The first surface portion and the heat receiving portion have a first contact boundary therebetween. The second surface portion and the resinous member have a second contact boundary that surrounds the first contact boundary. The second contact boundary is sealed using a sealing member. The sealing member is restricted from flowing into a boundary between the first contact boundary and the second contact boundary.
