Abstract: The present disclosure provides a flow rate measuring device including a flow rate detecting body, a humidity detecting body, and a base. The flow rate detecting body protrudes inside of an intake passage. The humidity detecting body protrudes inside of the intake passage at a position away from the flow rate detecting body. The base is connected to the flow rate detecting body and the humidity detecting body. The humidity detecting body holds a sensor chip that includes a humidity detecting element sensitive to the humidity of the intake air. A length, along a flow direction of the intake air, of an exposed portion of the humidity detecting body is defined as a referential length. The humidity detecting element exists within a range from an upstream end of the exposed portion of the humidity detecting body to a position of half the referential length.

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.

Abstract: An air flow measuring device includes a housing, a sensing part, a temperature sensor, a supporting member, and a protective projection. The housing defines a bypass flow passage which guides a part of air flowing in a duct. The sensing part is disposed in the bypass flow passage to measure a flow rate of air in the bypass flow passage. The sensor detects temperature of air flowing in the duct outside the housing. The supporting member supports the sensor at a predetermined measurement position. The protective projection is a projection, which projects outward from a side surface of the housing and is formed by mold removal in one direction. An end of the protective projection is located outward of the sensor. The protective projection makes contact with an object approaching the sensor from outside the housing to limit contact of the object with the sensor.
