In the field of process control automation, magnetic flap level gauges are common field indication instruments, which are widely used in large power and chemical enterprises such as power plants and chlor-alkali plants. Due to the wide variety of magnetic flap level gauges – such as those with top mounting, side mounting, those equipped with remote signal output, those with vacuum jacket insulation, those with steam jacket insulation, those with electric heating for insulation, and anti-corrosion versions – selecting the appropriate model presents certain difficulties. Choosing the right model correctly has a direct impact on whether the magnetic flap level gauge can perform reliable level measurement. Depending on the installation method, magnetic flap level gauges are divided into side-mounted magnetic flap level gauges and top-mounted magnetic flap level gauges. The side-mounted type is more common, but when dealing with storage tanks located underground, the top-mounted type is chosen to facilitate installation. In addition to enabling on-site display, magnetic flap level gauges can also be used for remote control by being equipped with reed switch remote transmitters or magnetic switches; in cases where the operating conditions at the site are harsh and involve explosive environments, an explosion-proof version is required. Furthermore, depending on the operating conditions, especially during winter in northern regions or when there are frequent low-temperature conditions at the measurement site, it is necessary to choose insulated products. There are mainly three types of insulated products: vacuum jacket insulation, steam jacket insulation, and electric heating insulation. Among these, electric heating insulation is relatively easy to install, while steam jacket insulation requires corresponding heating steam. When measuring in the presence of corrosive media, it is necessary to consider using corrosion-resistant products. There are various types of such products, such as those made of PP, PVC, or with a Teflon lining; among these, those with a Teflon lining offer the best corrosion resistance, but their manufacturing process is more complex and their price is slightly higher than that of other products. The choice of other accompanying devices is also very useful for subsequent maintenance; for example, users can opt for products equipped with drain valves and sewage discharge valves. During use, it is inevitable that the inner cavity of the conduit becomes clogged with dirt from the measuring medium, which can affect the proper operation of the magnetic float; in such cases, a drain valve allows the issue to be easily resolved by cleaning the inner cavity. To meet the various needs of customers and accommodate the different chemical properties of various liquids to be measured, the Flap-11 series of magnetic flap level gauges, independently developed by Shenzhen Jiwei Automation Technology Co., Ltd., comes in several specific models for use: The Flap-11S economic magnetic flap level gauge is made of 304 stainless steel; it is cost-effective and practical, and suitable for measuring liquids under most operating conditions as well as those with mild corrosiveness ； Flap-11A standard magnetic level gauge: made of 316L stainless steel, suitable for measuring most corrosive liquids ； Flap-11P lined magnetic flap level gauge: The float is made of 304 material lined with PTFE, and is used for measuring highly corrosive liquids ； Flap-11C plastic magnetic flap level gauge: The float is made of PP/PVC, and it is suitable for measuring low-pressure, highly corrosive liquids. At the same time, to make it more convenient for customers, Jiwei Automation has also developed two products: the SW-11 magnetic switch and the Reed-11 reed switch remote transmitter (both of which have obtained dual explosion-proof certifications for flameproofing and intrinsically safe operation). These products are used in conjunction with the Flap-11 series magnetic flap level gauges to enable automatic control and remote operation of liquid levels. The above is the information regarding the selection of magnetic flap level gauge models. If you wish to learn more about level switches, feel free to follow the WeChat official account: Jiweimeter.
