Abstract: An air flow meter includes an inward part that is positioned inward of an intake pipe and an outward part that is positioned not inward but outward of the intake pipe. The air flow meter further includes a first detector provided in the inward part, and a second detector provided at a position closer to the outward part than the first detector.

Abstract: A physical quantity measurement device measures a physical quantity of a fluid. A detection unit has a physical quantity detector that detects a physical quantity of the fluid in a measurement flow channel. A housing accommodates at least a part of the detection unit and forms the measurement flow channel. The housing includes a housing attachment that is attached to a predetermined attaching target, and a position holder holding a position of the detection unit by contacting the detection unit. The housing includes an inward part positioned inward of the attaching target and an outward part positioned outward of the attaching target. The position holder is provided inward of the housing attachment in an alignment direction along which the inward part and the outward part are aligned.

Abstract: A physical quantity measuring device detects a physical quantity of gas flowing in a flow passage. The physical quantity measuring device includes a sensor element that outputs a detection signal according to the physical quantity, a case that is provided to the flow passage and houses the sensor element, and a protrusion that protrudes from a passage wall surface facing the flow passage. The case includes a measurement chamber that houses the sensor element and an inflow port that is configured to cause a part of gas flowing in the flow passage to flow into the measurement chamber therethrough. The protrusion is configured to guide gas flowing along the passage wall surface toward the inflow port.

Abstract: A sensor body contains a sensor element in a body recess opened at a body opening. A sensor substrate has a mounting surface on which a circuit element for processing a detection signal is mounted and holds the sensor body on the mounting surface. A sensor cover has a cover window penetrating between an intake passage and the body opening and covers the sensor body. A sensor filter is interposed between the sensor body and the sensor cover. A potting resin body is cured on the mounting surface so as to seal the circuit element. The sensor cover is embedded in the potting resin body on the outer peripheral side of the sensor body.

Abstract: The present disclosure provides an air flow rate measuring device disposed in an intake air passage. The air flow rate measuring device measures a flow rate of the intake air flowing through the intake air passage. The air flow rate measuring device includes a casing, a flow rate sensor, and a sensor module. The casing defines a bypass passage to take in a portion of the intake air. The flow rate sensor is disposed in the bypass passage. The flow rate sensor generates an output signal according to a flow rate of the intake air. The sensor module protrudes from an outer wall of the casing. The sensor module includes a multi-sensor unit that has a relative humidity sensor and a temperature sensor. The relative humidity sensor is exposed to an inside of the intake air passage to detect a relative humidity of the intake air flowing through the intake air passage. The temperature sensor detects a temperature of the intake air flowing through the intake air passage.
