Analysis of installation techniques of magnetic flap level gauge for high liquid level tank [Copy link]

   Magnetic flap level gauge is also called magnetic level gauge, magnetic column level gauge, magnetic float level gauge. Its working principle is to use the principle of magnetic coupling. It is one of the level measuring instruments used in a large number of storage tank areas. It has its advantages over other types of instruments. In many cases, the magnetic flap level gauge has a simple structure, intuitive reading, good working stability, large measuring range, and is not limited by the height of the storage tank. It is easy to install (there are side-mounted and top-mounted), and it makes up for the shortcomings of glass tube level gauges that are easy to break under high temperature and high pressure. It eliminates the impact of the broken measuring tube on production and personal injury to operators. It has become the preferred product for measurement in liquid tank areas. Magnetic flap level gauges are divided into top-mounted and side-mounted. In industrial applications, there will definitely be various storage tanks on site, including horizontal tanks, underground tanks, and high-length tanks. Since the top-mounted installation method lacks support, it is recommended that the maximum should not exceed 5 meters. The measuring range of the side-mounted type can be selected at will, and generally there is no problem with a 10-meter tank. The installation method should be selected according to the specific requirements of the production site and the specific conditions of the tank. The connection part between the top-mounted magnetic flap level gauge and the tank body is generally equipped with a DN80 or DN100 flange connection. If you feel that it is not firm enough, you can choose a larger connection flange according to the actual situation. In general, DN80 and DN100 are sufficient. When the top-mounted magnetic flap level gauge is installed at a high height of 4 to 5 meters, it is recommended to add fixed cables on both sides to ensure that the instrument will not be damaged in a harsh measurement environment, such as large vibrations on site, or sometimes encounter collisions. The liquid level height of the magnetic flap level gauge is affected by technology. For example: when measuring a 10-meter high liquid level storage tank, if you directly choose to make a 10-meter long magnetic flap level gauge product, it will be clumsy and inconvenient to transport, so it is recommended to reasonably adopt segmented processing, so that there will be no technical errors (blind spot effects). The advantage of the magnetic flap level gauge is that it can be installed in split parts. This is convenient for transportation and the cost will be greatly reduced. Users only need to dock the flanges after receiving the goods. As for corrosion protection and leakage, we have also taken them into consideration. Specific problems are analyzed specifically. The magnetic flap level gauge can be equipped with electric remote transmission and output a standard signal of 4 to 20 mA to cooperate with recording instruments or industrial control computer networking. 10 meters and above is a bit long. Regardless of whether it is segmented or not, it is recommended to fix it with a clamp or other fixings around the flange of the middle part or each segment. When installing, the magnetic flap level gauge must be kept in a vertical state. A ball valve should be installed between the magnetic flap level gauge and the container lead pipe to facilitate the maintenance and disassembly and cleaning of the level gauge. The side-mounted lined magnetic flap level gauge (PP) is suitable for the measurement of inorganic corrosive liquids such as hydrochloric acid and dilute sulfuric acid. The side-mounted lined magnetic flap level gauge (PTFE) is suitable for level measurement in corrosive media and high working temperature. It uses the leading new technology of stainless steel lined polytetrafluoroethylene stretching flange, which has a reliable structure and a long service life. It is the best choice for level measurement of highly corrosive media such as hydrofluoric acid. Before use, the small ball below the zero position should be set to red with a calibration magnet, and the other balls should be set to white.
