Abstract

유동매체량을 측정하게 위한 공지된 장치는 유동매체가 주위를 흐르는 온도 관련 작동성의 측정엘리먼트를 가지고, 상기 측정엘리먼트는 측정통로내에 설치되어 있다. Known devices for measurement of the amount of the fluid medium has a temperature measuring element sex-related operation is the fluid medium flowing around the measuring element is disposed in the measuring passage. 이 측정통로내에서 발생하는 흐름의 불안정한 분리는 난류 중에 있어서, 측정엘리먼트로부터 발생하는 측정신호와 소위 베이스노이즈를 생기게하고 그 결과 정밀한 측정이 곤란하게 된다. The measurement unreliable separation of flow occurring in the passage is in the turbulent flow, causes a measurement signal and a so-called base noise generated from the measuring elements and as a result, the precise measurement becomes difficult.
본 발명에 따른 장치는 측정통로(33)의 입구개구(36)범위에 있어서 측정엘리먼트(33)의 상류측에서 유동방해부(50)를 가지고, 이 유동방해부가 트립엣지(51)로서 형성되며, 그 결과 상기 트립엣지(51)의 범위에서 시간적으로 또한 공간적으로 안정한 분리구역(54)이 생기게 되고, 이에의해 시간적 및 공간적으로 불안정한 분리구역의 발생이 방지되며, 그 결과 측정신호 노이즈의 감소가 얻어진다. Device according to the invention has a flow-impeding portion (50) upstream of the measuring element 33 is in the range inlet opening 36 of the measurement channel 33, is formed as a flow-impeding portion trip edge 51 , so that the terms of time in the range of a trip edge (51) also is causing spatially stable separation zone (54), whereby temporally and spatially, and prevent the occurrence of an unstable separation zone, and as a result reduction of the measurement signal noise, It is obtained.
본 발명은 유동매체의 량을 측정 특히, 내연기관의 흡입공기량의 측정을 위해 설치된다. The present invention is provided for the measurement of the amount of intake air of the measurement in particular, an internal combustion engine a quantity of the fluid medium.
