Many technicians in daily life will encounter the problem that the magnetic flap level gauge has a blind zone. Jinli Instrument will explain this problem to everyone, and hope to help you in your future work.
First of all, the float itself must have a length, even if it is short, there is a length. When the liquid level is zero or close to zero, in order to achieve accurate measurement, the float must be measured at zero level, so the blind spot must be Consider the length of the float below the zero level. Developed according to the buoyancy principle and magnetic coupling.
When the liquid level in the container under test rises and falls, the magnetic float in the body plate of the magnetic flap level gauge also rises and falls, and the permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling to drive red and white turning. The column is turned 180°. When the liquid level rises, the column changes from white to red. When the liquid level drops, the column changes from red to white. The red-white junction of the indicator is the actual height of the liquid level inside the container. Clear indication. The range of the magnetic flap level gauge of Jinhu Jinli Automation Instrument Co., Ltd. is the distance between the centers of the two flanges, and the upper flange to the top of the tank and the lower flange to the tank are the so-called blind spots, but if you know this If there is a distance between the segments, there will be no blind spots. It can be calculated when designing the tank. Such a mounting structure is caused by the working principle of the magnetic flap level gauge.
