1. 일반사항
1.1 소개
㈜와이즈에서 제작하는 벤츄리 콘(Venturi cone)은유체가 흐르는 관로 중간에 설치하며,
유체가벤츄리 콘내부의 원뿔 주위를 흐를 때유체의 속도를 재구성하여 원뿔의 하류 방향으로 낮은 압
력이 형성되며, 이때, 원뿔을 중심으로 전,후압력 차를 생성하여 유량을 측정하는 유량계 입니다.
벤츄리 콘(Venturi cone)은고객의 사양에 따라 제조되는 제품 입니다.
1.2 사용설명서 관련 정보
1) 본사용설명서에는 장치의 올바른 취급에 관한 중요한 정보가 들어 있으므로 설치 및시험 운전을 하

3. 제품 설치 전점검 사항
1) 제품의 태그 번호 및설치될 위치의 제품인지 확인하십시오.
2) 용접 윤곽선, 돌출 부분 등이 없어야 하며, 설치 전에 벤츄리 콘표면에 찌그러짐이나 긁힘이 있는지 확
인해 주십시오.
3) 배관 내부는 부드럽고 깨끗해야 하며, 이물질이 없는지 확인해 주십시오.
4. 제품 설치 및조작 방법
4-1. 기본 사항
벤츄리 콘(Venturi cone)에의해 생성된 차압은 전,후단 압력 탭의 연결로 배출 됩니다.
연결 부분은 유체 흐름 방향 기준으로 전단 탭, 후단 탭으로 구분됩니다.
유체 흐름 방향은 명판(Name plate)에표시 됩니다.(<Figure 1> 참조)
