    摘要: A diversion passage is constructed into an inverted U shape in which an upstream diversion passage and a downstream diversion passage each having a passage direction in a direction of projection of a detector flow tube communicate by means of a curved portion. An inflow port is constructed by removing a portion of a wall of the upstream diversion passage on an upstream side in the main direction of flow, and removing a portion of first and second side walls of the upstream diversion passage facing each other in a direction perpendicular to the main direction of flow and the direction of projection of the detector flow tube. In addition, a wall surface on a downstream side of the upstream diversion passage in the main direction of flow at the inflow port is formed into a curved surface shape that is gradually displaced upstream relative to the direction of projection of the detector flow tube to constitute an air lead-in surface.

    摘要: A highly accurate thermosensitive flow rate sensor is able to reduce the detection error of a flow rate even in the case of a flow accompanied by considerable intake air pulsation in an automotive engine or the like. A flow rate detecting section disposed in a main pipe is equipped with a support member having a first guide surface and a second guide surface for guiding a fluid on opposite sides thereof, and a flow rate detection element provided on the second guide surface of the support member. The second guide surface of the support member, on which the flow rate detection element is mounted, extends longer than the first guide surface in the downstream direction.

    摘要: A flow rate sensor comprises: a main fluid passage for a fluid to flow therealong; a detecting pipe conduit coaxially disposed in the main fluid passage; a temperature sensing element for sensing the temperature of the fluid; a flow rate sensing element including a flow rate detecting resistance made of a thermo-sensitive electrically resistant material, the flow rate detecting element being disposed in the main fluid passage in a manner such that the flow rate detecting resistance is exposed to the fluid flowing therethrough; and a control circuit for controlling an electric current flowing to the flow rate detecting resistance such that the temperature of the flow rate detecting resistance may be maintained at a predetermined value which is higher to some extent than a fluid temperature detected by the temperature sensing element. The main fluid passage involves a converged section whose passage cross sectional area becomes gradually smaller towards the downstream side thereof. At least one portion of an inner surface of the converged section cut by a plane containing the central axis of the main fluid passage is formed by a generally three dimensional curved surface. The inlet of the detecting pipe conduit is disposed in a direction in which the fluid flows, in a manner such that the inlet of the detecting pipe conduit is at a position close to the narrowest portion of the passage cross sectional area of the converged section.

    摘要: A flow rate sensor comprises a fluid passage for a fluid to flow therealong; a main body structure arranged so as to turn its front end to the upstream side of the fluid and coaxially positioned within the fluid passage; and a detecting element disposed between the main body structure and the internal surface of the fluid passage. The main body structure is formed such that its cross section perpendicular to its central axis, at first becomes gradually larger from its front end towards its rear end and then becomes gradually smaller. The detecting element includes a ceramic substrate coated with a film made of a thermo-sensitive electrically resistant material. The film is formed into a meander pattern so as to form a flow rate detecting resistance. The detecting element further includes a fluid temperature compensating resistance.

    摘要: A heat-sensitive flow rate sensor that is high in productivity, superior in accuracy of flow rate measurement and sensitivity. A bottom face of a concave accommodating portion 18 of an supporting member 16 is provided with an adhesion face 24 for fastening a flow rate-detecting element 14 thereon with an adhesive 15, installation faces 25a, 25b for holding the flow rate-detecting element 14 thereon, and a protruding face 26 for blocking in a raised manner the whole area of a cavity 13 on the underside of the flow rate-detecting element 14. As a result of employing this construction, even when increasing an intake fluid to a large amount of flow, the protruding face 26 blocks the vicinity of the cavity 13. Therefore, the fluid to be measured hardly flows into the gap between the underside of the flow rate-detecting element 14 and the supporting member 16. Consequently, accuracy in flow rate measurement is improved. Furthermore, the protruding face 26 is formed slightly larger than the area of the cavity 13 in the flow rate-detecting element 14, thereby preventing an underflow. As a result, assembling the flow rate-detecting element 14 becomes easier, which is suitable for large-scale production.
