    摘要: In a sensor chip for a fluid flow sensor, a thin film portion is formed above a hollow cavity portion while leaving thin film layers formed on the surface of a substrate. A conductor is provided on the inner wall face of a through hole formed to penetrate the substrate to thereby electrically connect a detecting portion constituted by a conductor film in the thin film layers and a substrate conductor portion formed on the rear face side of the through hole. The surface of a circuit board is formed with a control circuit and a base conductor portion electrically connected to the control circuit. The sensor chip and the circuit board are layered and the substrate conductor portion and the base conductor portion are electrically connected.

    摘要: A flow meter is formed with a passage for introducing and carrying air to measure and has a sensing part disposed in the passage for measuring a flow rate of the air. A contraction part is formed on an inner surface of the passage so that the contraction part faces the sensing part. The contraction part narrows the flow of the air flowing near the sensing part. A flat surface of the contraction part is formed in parallel with the surface of the sensing part and at least upstream of the sensing part. Thus, collision of particles against the sensing part and adhesion of contaminants to the sensing pert are inhibited. Meanwhile, the flow rate of the air is measured stably and accurately.

    摘要: An airflow meter has a membrane type sensor element. The sensor element is supported on a support member so that a sensing surface of the sensor element is in parallel to the airflow direction. The airflow meter has at least one means for protecting the sensor element from dust such as foreign particles. The protecting means is provided with an obstruction member that is disposed upstream or downstream of the sensor element with respect to the airflow direction. The sensor element is hidden behind the obstruction member. The obstruction member has gradually spreading surfaces and gradually converging surfaces along the airflow direction. Alternatively, the protecting means can be provided with a deflector, a cover member, a flow guide member, an inlet or a dust collector.

    摘要: An air flow rate measuring apparatus includes a heater and a control circuit. The heater heats a part of an intake air sucked into an engine. The control circuit controls an energization of the heater. The heater has a measuring-mode temperature when a flow rate of the intake air is measured. The control circuit has a heat cleaner which temporarily raises a temperature of the heater higher than the measuring-mode temperature when an energization of the air flow rate measuring apparatus is started.

    摘要: According to a flow measuring device, first ranges formed by a first plurality of resistors form a single continuous value range on a flow direction coordinate axis. Thus, the first plurality of resistors is limited from being thermally insulated from one another in the flow direction, and thereby detectivity is improved. Also, second ranges formed by a second plurality of resistors form an other single continuous value range on a longitudinal direction coordinate axis. The other continuous value range includes a position that corresponds to a half length of a heating element in a longitudinal direction. As a result, detection difference is obtained at the position, at which a temperature is most optimally detected, and thereby detectivity is further improved.
