1. Requirements for float installation: To prevent the float from sliding and getting damaged inside the float tank during transportation, the magnetic flap level gauge should have the float secured to the edge of the float tank using a nylon strap before it leaves the factory. Before installation, open the lower flange, then insert the heavier end of the magnetic float, That is, the magnetic end, upward into the float tank; be careful not to insert it in the wrong orientation. 2. Valve installation requirements: A valve should be installed between the magnetic flap level gauge and the container, so as to allow the flow of material to be stopped at any time for cleaning and maintenance purposes. 3. Requirements for the internal and external environment of the float: Magnets are not allowed to be in proximity to the cylinder of the magnetic flap level gauge; in particular, the use of iron clamps is prohibited, as this can affect the proper functioning of the level gauge ； Moreover, the medium should not contain any solid impurities or magnetic materials to prevent obstruction of the float. Depending on the conditions of the medium, the float should be cleaned regularly to remove internal impurities. 4. Before use, use a calibration magnet to set the flaps below the zero position to red, and the other flaps to silver-white. 5. When putting the magnetic flap level gauge into operation, first open the valve of the upper liquid inlet pipe, then slowly open the valve of the lower liquid inlet pipe to allow the liquid medium to flow in smoothly. This prevents the liquid medium from pushing the float upward rapidly, which could cause the flaps to malfunction or become disordered (in case this occurs, a magnet can be used for correction). 6. Installation requirements for top-mounted magnetic flap level gauges: When installing top-mounted magnetic flap level gauges, the guard tube and the main tube of the gauge must remain vertical and on the same vertical line; the float rod must not be bent and should be inserted in a straight position. 7. Installation requirements for corrosion-resistant magnetic flap level gauges: For 304-lined PTFE corrosion-resistant magnetic flap level gauges, a unique sealing structure is used at the junction between the float and the flange; therefore, special tools are required for assembly. To ensure the reliability of the seal, disassembly after leaving the factory is prohibited, otherwise the user will bear the consequences. http://file.elecfans.com/web1/M00/81/47/o4YBAFwvFVmASbf8AAG9MD-rK4c465.png 8. Installation requirements for ultra-long magnetic flap level gauges: For ultra-long magnetic flap level gauges (with a measurement range of more than 4 meters), the logistics and transportation costs are high; therefore, such gauges are usually manufactured in sections. There are two forms of the segmentation method, which can be chosen based on the actual interface format of the customer’s on-site equipment. In Figure 1, the level gauge is divided into two sections; during installation, the connection flanges are first assembled and connected together. The display panel can be slightly loosened while carrying out the connection process. The number of support points depends on the length of the level gauge ； In Figure 2, the design consists of two or several separate level gauges. For this configuration to work, the centerlines of the two flanges located in the middle of the storage tank must be on the same horizontal level, in order to ensure continuous level indication.
