Claims (3)
- 측정 수단을 구비하고, 상기 측정 수단을 이용하여 정확한 양의 용액을 저장 및 공급하는 측정 탱크에 있어서, 상기 측정 탱크에 용액을 공급하기 위하여 측정 탱크의 측면에 설치된 공급관과; 상기 측정 탱크의 상부에서 상기 측정 탱크 내에 삽입된 피스톤과; 상기 피스톤을 통하여 전달되는 측정 탱크 내의 압력을 검출하도록 상기 피스톤의 상부에 설치된 압력 검출부와; 상기 압력 검출부를 통하여 검출되는 상기 측정 탱크의 압력이 상기 압력 검출부에 설정되어 있는 기준 압력과 다른 경우에 상기 측정 탱크 내의 압력을 조절하도록 상기 피스톤을 구동하기 위한 피스톤 구동 수단과; 상기 측정 탱크의 압력이 기준 압력보다 높은 경우에 상기 피스톤의 동작에 따라 역류하는 용액을 배출시키기 위한 배출관을 포함하는 측정 탱크.
- 제1항에 있어서, 상기 압력 검출부는, 상기 피스톤의 측면에 부착되어 피스톤의 상하 운동에 따라 동작하는 링크와; 상기 링크의 동작에 따라 소정의 각도로 회전하는 회전체와; 상기 회전체의 회전에 의하여 전달되는 압력을 검출하는 압력 센서와; 상기 압력 센서를 통해 압력의 크기를 전달받아 상기 피스톤을 제어하는 제어부를 포함하여 이루어진다.
- 제1항에 있어서, 상기 피스톤 구동 수단이 압력 펌프인 것이 특징인 측정 탱크.
