    • PURPOSE: A gas flow sensor, which senses a flow rate of general gas and flow rate of breathable airflow, is provided to simplify the structure of a gas flow sensor including a pressure sensor. CONSTITUTION: A gas flow sensor, which senses a flow rate of general gas and flow rate of breathable airflow, comprises a chamber(70), first and second pressure taps(71,72) and a pressure sensor(73). The first and second pressure taps are included in the left and right sides of the chamber. The pressure sensor is connected to the first and second pressure taps in order to measure the pressure difference between right and left sides of the chamber. The inside of the chamber is hollow form. The inside diameter of the center part of the chamber is larger than that of the left and right side of the chamber.
    • 目的:提供一种检测一般气体的流量和透气气流的流量的气体流量传感器,以简化包括压力传感器的气体流量传感器的结构。 构成:感测一般气体的流量和透气气流的流量的气体流量传感器包括室(70),第一和第二压力抽头(71,72)和压力传感器(73)。 第一和第二压力抽头包括在腔室的左侧和右侧。 压力传感器连接到第一和第二压力抽头,以便测量室的左右两侧之间的压力差。 室内是中空的。 室的中心部分的内径大于室的左侧和右侧的内径。
