原理： Principle of magnetic flap liquid level gauge :
The magnetic flap liquid level indicator is installed on the outside or above of the tub, which is used to indicate and control the seal inside the tub. A drain valve can be added as required. The connection flange can be a control instrument for customizing the liquid level height. The indicator consists of magnetic color chips. When the magnetic floating ball in the body tube rises with the liquid level, the color film is flipped to display the liquid level height. It is also possible to install a magnetic switch or remote transmitter on the body tube to output a switch signal or an analog signal. It is suitable for high temperature, high pressure, corrosion resistance and other occasions. It can be displayed and controlled remotely. The body pipe is made of seamless steel pipe, and the connecting pipe is welded with pull holes, and there is no scratch inside. The installation method can be side or top, and the lower end of the body is sealed.
This product is also called magnetic level gauge, magnetic flip column level gauge, magnetic float level gauge.It uses the principle of magnetic coupling to work.The product makes up for the glass tube level gauge which cannot work under high temperature and high pressure and is fragile. Multiple disadvantages.
There are two installation methods, side-mounted and top-mounted, no matter which method can be bundled with a remote transmission device, so that the liquid level gauge can display the liquid level on the spot and remotely monitor the liquid level. It can be called a remote transmission magnetic flap level gauge.
要选择有生产许可证且信誉好的厂家,价格可能略高一点,但产品质量有保证,售后服务有保证。 Although the process of making the magnetic flap liquid level gauge is very simple, the magnetic flap liquid level gauge is used as a measuring instrument, especially the remote transmission magnetic flap liquid level gauge. If it has not been audited by the Quality Supervision Bureau, there is no production license, and the product It is difficult to guarantee the quality. Therefore, when purchasing a magnetic flap level meter, choose a manufacturer with a production license and a good reputation. The price may be slightly higher, but the product quality is guaranteed and the after-sales service is guaranteed.
The glass plate level gauge can be directly used to observe the liquid level height of various media in the container. It is suitable for liquid level indication in the petroleum, chemical and other industrial fields. The liquid level gauge has a simple structure, intuitive and clear observation, no clogging and leakage, convenient installation and simple maintenance. The upper and lower mounting flanges of the glass plate level gauge are connected to the container to form a connector. The actual height of the liquid level in the container can be directly observed through the glass plate. The upper and lower valves are equipped with safety steel balls. When the glass is accidentally damaged, the steel balls are automatically sealed under the pressure of the container to prevent the liquid in the container from overflowing and ensure the safety of the operator.
How to install the magnetic flap level meter:
为接触式测量，测量时要考虑接液材质问题。 The magnetic flap liquid level gauge is a contact type measurement, and the problem of wetted material should be considered when measuring. Your medium must be anti-corrosive. If you do n’t need remote transmission, you do n’t need power supply, but if you want remote transmission, you also need power. The installation is generally flange butt. It is not too troublesome if the site conditions allow it. His biggest advantage is that it is intuitive to look at. Other highly volatile media that require explosion-proof measurement media are also good for magnetic flaps. The magnetic flap liquid level gauge must be installed vertically. A ball valve should be installed between the magnetic flap liquid level gauge and the container guide tube to facilitate maintenance and cleaning. The installation position of the magnetic flap liquid level gauge should be avoided or away from the material medium inlet and outlet. To avoid rapid changes in the local area of the material fluid, which affects the accuracy of the level measurement; the medium should not contain solid impurities or magnetic substances to avoid blocking the float; before use, the magnetic steel should be used to adjust the The small ball is set in red, and the other balls are set in white. Open the bottom flange and install the magnetic float (note: the magnetic end with the heavy end is up and cannot be inverted.); When debugging, open the upper lead valve and then slowly open The lower valve allows the medium to enter the main pipe smoothly (the medium should be prevented from impacting the float sharply during operation, which will cause the float to fluctuate and affect the accuracy of the display). Observe whether the magnetic red and white ball is flipped normally, and then close the lower introduction valve and open the drain valve. Allow the liquid level in the main duct to drop, and operate three times according to this method, which is normal and ready for operation (except for special liquids such as corrosive)
