The magnetic flap liquid level meter has very good results in liquid level measurement and dosing measurement in the environmental protection industry.

Rachel Carson, a well-known American science writer, caused a sensation with her 1962 publication of "Silent Spring." In the 1960s, the United States did not talk about "protecting the environment." In order to develop its economy and fight the Soviet Union, slogans such as "declaring war on nature" and "conquering nature" resounded throughout every inch of the United States. However, the publication of this book hit the head of the poor bourgeoisie at that time, making some people see the serious consequences of "three wastes" pollution on the United States.

Topics such as "three wastes" pollution and environmental protection are not limited to the United States. China also attaches great importance to the monitoring and treatment of wastewater and sewage. In the second season of "Reader" broadcast on CCTV in 2018, "Quiet Spring" was put on the stage through "reading through time and space", which moved countless audiences. Speaking of sewage monitoring, today we are going to talk about the contribution of magnetic level gauges.

Magnetic flap liquid level gauge is a common liquid level gauge, widely used in food, chemical, oil refining and other industries. According to the principle of buoyancy and magnetic coupling, when the liquid level rises, the magnetic plate flips and changes color. When the liquid level drops, the magnetic plate reverses. The magnetic plate in the instrument consists of positive and negative red and black parts. The intersection of these two colors is the actual height of the fluid level.

In sewage, many substances can cause harm to the human body, so even sewage treatment personnel should take protective measures to avoid contact with operations as much as possible. One of the advantages of the magnetic flap level gauge is that it is easy to install, and it is also very convenient to clean the level gauge during use. Usually, the magnetic flap level gauge is indirectly observed on site, but for safety reasons, we can add remote monitoring to the instrument, and the measurement data can be indirectly and remotely transmitted to the background for display even when not on site.

If the magnetic level gauge is used improperly or neglected during maintenance, it may malfunction. So in sewage treatment, what kind of failures will happen to the magnetic flap level gauge? How to solve it?

Since most of the sewage treated is liquid with strong alkali, if it is not handled properly during the installation process, the float may corrode and leak due to short use time. If a problem occurs, the float will not change with the increase of the liquid level, so we cannot observe the accurate value through the liquid level meter. What should we do in this situation?

First, for a faulty liquid level gauge, close the valve, remove the liquid level gauge, replace the float, and take anti-corrosion measures such as spray coating on the entire liquid level gauge. In addition, before purchasing a liquid level meter, we should conduct a thorough investigation of the medium being measured. If there are corrosive elements in the medium, you should not use a general magnetic level gauge, but a special anti-corrosion magnetic level gauge, which will be worse in terms of service life and terminal maintenance.

Through this article, do you have a better understanding of the role of magnetic flap level gauges in sewage treatment? Environmental protection is everyone's responsibility. Sewage treatment is urgent. We should start from the small things around us and contribute to environmental protection.
