Description

캐비티(cavity)유량계Cavity flowmeter

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 캐비티 유량게에 대한 구성원리도,1 is a member diagram for the cavity flow rate gauge of the present invention,

제2도는 캐비티 유량계의 완성된 예시 단면도,2 is a completed exemplary cross-sectional view of a cavity flow meter,

제3도는 (a),(b),(c)는 제2도를 이용한 실험예의 결과 도면.3 is a diagram showing results of an experimental example using (a), (b), and (c).

Claims (2)

유체가 관속을 흐를때 발생되는 발진을 이용하여 유량을 측정하는 유량계에 있어서, 유로(1)에 캐비티(2)를 형성시키고, 이 캐비티(2)에 유체발진을 감지하는 압전소자(3)를 설치하며, 상기 압전소자(3)로부터의 출력이 증폭기(4)와 디비탈회로(5)에 입력되어서 유량을 측정하도록 구성된 것을 특징으로 하는 캐비티 유량계.In the flow meter for measuring the flow rate by using the oscillation generated when the fluid flows through the tube flow, the cavity (2) is formed in the flow path (1), the piezoelectric element (3) for detecting the fluid oscillation in the cavity (2) And the output from the piezoelectric element (3) is input to the amplifier (4) and the digital circuit (5) to measure the flow rate. 제1항에 있어서, 캐비티(2)는 유체가 흐르는 관에 착탈식으로 조립되어지는 것을 특징으로 하는 캐비티 유량계.Cavity flow meter according to claim 1, characterized in that the cavity (2) is detachably assembled to the pipe through which the fluid flows. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
