摘要： A heat sensitive flow amount sensor of the invention includes a measuring pipe disposed in the inlet pipe of an internal combustion engine, an air flow amount detecting element disposed in the measuring pipe for detecting the flow amount of intake air flowing in the inlet pipe making use of the fact that a quantity of heat loss corresponds to the flow amount of the intake air, and a straightening member disposed on the outer periphery of the measuring pipe along the axial line thereof for straightening the intake air flowing into the measuring pipe by straightening the intake air flowing in the inlet pipe. With this arrangement, even if the heat sensitive flow amount sensor is disposed in the vicinity of a throttle valve, the measuring accuracy of the flow amount of air is not lowered and the size of an internal combustion engine can be reduced by the employment of the heat sensitive flow amount sensor.

摘要： A thermo-sensitive flow rate sensor that has a flow rate detecting device, in which a heating element constituted by thermo-sensitive resistor film, is formed on a top surface of a plate-like substrate and in which a diaphragm is formed by partially removing the plate-like substrate. This sensor further has a supporting element arranged in such a way as to have a top surface that is parallel to the direction of flow of a fluid to be measured. The flow rate detecting device is supported and fixed in a recess portion formed in the supporting element so that the top surface of the device is nearly flush with the top surface of the supporting element. Further, the thin-plate-like member is attached to the back surface of the flow rate detecting device in such a way as to close a cavity.

摘要： A flow rate-measuring device capable of measuring accurately a flow rate of fluid to be measured containing a drift or eddy as compared with a conventional device is provided. A flow rate-measuring passage 11 for measuring a flow rate of the fluid to be measured is constructed so that its opening area in an upstream region communicating to an inlet 111 gradually decreases from upstream to downstream. A flow rate-detecting element 31 is disposed near an outlet in the flow rate-measuring passage 11. The device is provided with a leak flow passage 18 allowing a part of the fluid which has flown in from the inlet 111 of the flow rate-measuring passage 11 to leak out of the flow rate-measuring passage 11 at a portion upstream from an outlet 112 of the flow rate-measuring passage 11, in particular upstream from a position where the flow rate-detecting element 31 is disposed.

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.
