Description
본 고안은 액체 저장 탱크내 액위를 측정하기 위한 장치로서 용액에 잠긴 깊이에 따라서 일정한 체적의 부력 감지용 추에 작용하는 부력의 변화량을 연산하여 탱크내 액위를 측정하는 장치에 관한 것이다.The present invention is a device for measuring the liquid level in the liquid storage tank relates to a device for measuring the liquid level in the tank by calculating the amount of change in the buoyancy acting on the buoyancy detection weight of a constant volume according to the depth submerged in the solution.
종래의 탱크내 액체의 액위를 측정하기 위한 방법으로 전극봉 방식, 초음파 방식, 작용압력 환산방식, 액위의 변화를 부표의 높이변화로 감지하는 방식 등이 적용 되고 있으며, 이러한 종래의 측정 방식은 탱크내 액체에 전기적 신호의 흐름 및 신호의 출력을 위한 접점, 기계적 구동부 등이 포함된 것으로 부력 변화량 감지 방식을 적용한 액위 측정용 장치는 부족한 실정이다.As a method for measuring the liquid level of the liquid in the conventional tank, the electrode method, the ultrasonic method, the conversion of the working pressure, and the method of detecting the change of the liquid level as the height change of the buoy are applied. It detects buoyancy change as liquid contains electrical signal flow and contacts for signal output and mechanical drive. Apparatus for level measurement using the method is insufficient.
본 고안의 목적은 탱크내 액체의 액위를 측정하기 위하여 적용중인 전극봉 방식, 부표 방식 등 종래 방식의 문제점인 액체에 작용되는 전기적 신호의 입출, 기계적 구동부의 특성변화 등을 개선 하기 위하여, 본 고안에서는 탱크내 설치된 부력감지용 추에 작용되는 부력이 액체의 높이의 따라 변화하는 것을 이용하여 탱크내 용액의 액위를 측정한다.The purpose of the present invention is to improve the extraction of electrical signals acting on the liquid, changes in the characteristics of the mechanical drive, etc., which are problems of the conventional methods, such as the electrode method, buoy method, etc. being applied to measure the liquid level of the liquid in the tank. The liquid level of the solution in the tank is measured by using the buoyancy force applied to the buoyancy sensing weight installed in the tank according to the height of the liquid.

본 고안에 따르면 액체 저장 탱크내의 액위를 측정하기 위하여 부력 감지용추(1)를 탱크 내부의 바닥면 가까이 탱크의 외부에 설치된 중량 감지용 센서(3)와 연결용 로프(2)를 통하여 매달림 설치를 한다.According to the present invention, in order to measure the liquid level in the liquid storage tank, the buoyancy sensing weight (1) is suspended from the weight sensing sensor (3) and the connecting rope (2) installed on the outside of the tank near the bottom surface of the tank. do.
탱크내 용액이 들어올때 부력 감지용 추(1)가 용액에 잠기게되며 이때 부력감지용 추에는 용액의 깊이(7), 부력추의 부피(5), 용액의 비중(6)에 따른 부력이 작용되며 이부력은 부력용 추의 중량을 감소하는 힘으로 작용한다. 이때 용액속에 설치되는 부력용 추의 비중은 용액의 비중(6)보다 상당히 큰 재질을 사용하여 탱크내 용액의 흔들림 등에 안정해야 한다.When the solution in the tank enters the buoyancy detection weight (1) is immersed in the solution, the buoyancy detection weight is buoyancy according to the depth of the solution (7), the volume of the buoyancy weight (5), the specific gravity of the solution (6) The buoyancy force acts as a force to reduce the weight of the buoyancy weight. At this time, the specific gravity of the buoyancy weight installed in the solution should be stable, such as the shaking of the solution in the tank using a material significantly larger than the specific gravity (6) of the solution.
부력용 추에 작용하는 액위에 따른 부력의 변화량을 중량 감지용 센서(3)를 통하여 입력된 정보로 연산 출력장치(4)에서 액위로 환산 출력한다.The change amount of the buoyancy according to the liquid level acting on the buoyancy weight is converted into the liquid level by the arithmetic output device 4 with the information input through the weight sensing sensor 3.
이상에서와 같이 본 고안에 따르면 측정 하고자 하는 탱크의 깊이, 용액의종류에 따라서 유연한 적용성을 가진다. 또한 탱크내 액위의 변화에 따른 부력 감지용 추(1)에 작용하는 부력을 중량 감지용 센서(3)에서 연속적으로 감지하여 연산 출력장치(4)에서 출력함으로 액위의 흔들림 등에 영향이 적다.According to the present invention as described above has a flexible applicability according to the depth of the tank to be measured, the type of the solution. In addition, the buoyancy acting on the buoyancy sensing weight 1 according to the change of the liquid level in the tank is continuously detected by the weight sensing sensor 3 and outputted from the arithmetic output device 4 so that there is little influence on the shaking of the liquid level.
또한 가압중인 압력 탱크내의 액위 측정에도 유용하다.It is also useful for measuring liquid levels in pressurized pressure tanks.
