Abstract

본 발명은 유체의 유동률을 측정하는 유량계에 관한 것으로, 유체가 흐르는 주통로를 포함한다. 주통로의 중심에서 중심부재를 지지하기 위해 다수의 지지부재가 몸체 및 중심부재의 내벽면은 연결시킨다. 유도포트가 중심부재에 개방되어 주통로를 통해 흐르는 유체의 부분을 유도한다. 분지통로가 이 유체의 부분이 흐르는 중심 부채내에 형성되어 있다. 센서가 분지통로 안에 위치하여 분지통로안의 유동률을 측정한다. 유출구가 지지부재의 하루단의 상류에 위치한 중심부재의 부분에 개방되어 분지통로를 통해 주통로에 흐르는 유체를 귀환시킨다.The present invention relates to a flow meter for measuring the flow rate of the fluid, and includes a main passage through which the fluid flows. A plurality of supporting members connect the body and the inner wall surface of the central member to support the central member at the center of the main passage. An induction port is opened to the core material to guide a portion of the fluid flowing through the main passage. Branch passages are formed in the central fan through which a portion of the fluid flows. A sensor is located in the branch passage to measure the flow rate in the branch passage. The outlet port is opened to a portion of the core member located upstream of the end of the support member to return the fluid flowing in the main passage through the branch passage.
