What is a magnetic flap level meter and how to install it properly


:该仪表可用于各种塔、罐、槽、球型容器和锅炉等设备的介质液位检测。 What is a magnetic flap level meter : This meter can be used for medium level detection of various towers, tanks, tanks, spherical vessels and boilers. This series of level gauges can achieve high sealing, leakage prevention and suitable for high temperature, high pressure, and corrosion-resistant occasions. It compensates for the defects of poor clarity and easy fracture of the indication of the glass plate (tube) level gauge, and there is no blind zone in the whole process measurement, and the display is clear and the measurement range is large. The parts and components of the magnetic flap level meter are made of 1Cr18Ni9Ti, 316L, 0Cr18Ni9Ti, 1Cr18Ni9Ti lined with PTFE (polytetrafluoroethylene), PVC, PP and other imported components, and have excellent reliability and corrosion resistance. The magnetic flap liquid level gauge has the advantages of simple structure, convenient use, stable performance, long service life, and easy installation and maintenance. It is widely used in liquid level measurement, control and monitoring in petroleum processing, food processing, chemical industry, water treatment, pharmaceutical, electric power, papermaking, metallurgy, shipbuilding and boiler fields.

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)

The enterprise or industry innovation system is the most important subsystem of the national innovation system. It puts forward innovation requirements to the research and development system, and introduces the results of the research and development system into the industrial system. At the same time, it also continuously carries out innovation activities. The closer this innovation is combined with the production process, the more directly the gradual update of the production process and product can be achieved.
的安装与使用维护注意事项 Now let ’s take a look at the installation, use, and maintenance of magnetic level gauges .
1. Before use, the small balls below zero should be set to red with calibration magnets, and the other balls should be set to white; 2. If the user uses the heat tracing pipeline by himself, non-magnetic materials must be selected, such as copper tubes, etc. . The heat tracing temperature is determined according to the condition of the medium; 3. The installation position of the magnetic flap liquid level gauge should avoid or stay away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid and affect the accuracy of the liquid level measurement; 4. There should be no solid impurities or magnetic substances in the medium to avoid blocking the float. 5. The magnetic flap liquid level meter body is not allowed to have magnetically conductive substances approaching it. It is forbidden to fix the iron wire, otherwise it will affect the magnetic flap liquid level gauge. normal work. 6. Open the bottom flange and install the magnetic float (Note: the magnetic end with the heavy end is up and cannot be inverted.) 7. When debugging, first open the upper lead valve and then slowly open the lower valve to allow the medium to enter the main control smoothly. Tube, observe whether the magnetic red and white ball flip is normal, then close the lower tube valve, open the drain valve to lower the liquid level in the main conduit, and operate three times according to this method, which is normal and can be put into operation;
8. According to the condition of the medium, clean the main pipe from time to time to remove impurities; 9. For liquid level gauges that exceed a certain length (common type> 3 meters, anti-corrosion type> 2 meters), an intermediate reinforcement flange or ear climbing needs to be added for fixing Support to increase strength and overcome its own weight; 10. The magnetic flap liquid level gauge must be installed vertically, and a ball valve should be installed between the magnetic flap liquid level gauge and the container's guide tube for easy maintenance and cleaning; 11. When equipped with remote transmission When supporting the instrument, the following should be done: a) The remote transmission instrument should be close to the main pipe of the level gauge and fixed with a stainless steel hoop (iron is prohibited); b) The sensing surface on the remote transmission instrument should be facing and tight. Stick the main duct; c) The zero position of the remote transmission supporting instrument should be on the same horizontal line as the zero indicator of the liquid level gauge; d) The connection between the remote transmission supporting instrument and the display instrument or the industrial computer should be laid through a protective tube separately Or use a shielded two-core cable for laying; e) After laying the wire entry hole of the junction box, it is required to be well sealed to prevent the invasion of remote transmission equipment from working properly due to the intrusion of rain and moisture. The junction box should be covered in time after the maintenance or commissioning . This is the foundation of an enterprise's existence. It is also the forefront of technological application and innovation. From the perspective of technological change, the key to the success of technological innovation is whether the new technological concept can be applied to the production system of the enterprise or whether a new production system can be established. Because, a certain technology system or even a certain technological field or industry has undergone major changes in leaping technological innovation. The way to achieve it is not to transform and innovate in the existing production system, but to break or eliminate the original production system. Establish a new production system. The direct impetus for such innovation often comes from internal research thrust or market pressure, forcing companies to undergo major reorganizations.
