发明名称 AIRFLOW MEASURING DEVICE
摘要 A housing defines a bypass passage and a sub-bypass passage. The bypass passage draws a part of air flowing through an interior of a duct. The sub-bypass passage is branched from the bypass passage to draw a part of air flowing through the bypass passage. A flow sensor is equipped in the sub-bypass passage to cause heat transfer with air, which passes through the sub-bypass passage, and to generate an electric signal according to a flow quantity of air in the duct. An intake-air temperature sensor is configured to measure a temperature in the duct. A moisture sensor is configured to measure a humidity in the duct. The flow sensor and the multiple sensors are equipped in the sub-bypass passage and are located along a direction of flow of air in the sub-bypass passage.
