Magnetic flap level gauge installation requirements

Magnetic level gauge is a kind of common on-site indicating type liquid level instrument, widely used in liquid level measurement of tanks, storage tanks, boilers and other containers, even in the low temperature, high temperature, high pressure, strong corrosion and other bad Working conditions also work safely and reliably. But all this is based on the quality of the product and the correct installation of the magnetic flap level gauge itself with high seal leakage. So, what are the specific requirements when installing magnetic level gauges?
In general, the magnetic flap level gauge needs to be installed according to the following requirements:
1. Magnetic float installation requirements: In order to avoid the sliding impact damage of the magnetic floater in the floater during transportation, the magnetic flipper liquid level gauge is fixed to the floater with a nylon belt before leaving the factory. Open the lower flange before installation, and then put the heavy end of the magnetic float, that is, the magnetic end up into the buoy, and be careful not to flip it.
2. Valve installation requirements: Valves should be installed between the magnetic level gauge and the container so that the materials can be cut off at any time for cleaning and maintenance.
3, buoy internal and external environment requirements: magnetic flap level gauge cylinder around the body is not allowed to approach, especially the use of iron clamps, otherwise it will affect the normal operation of the level gauge; and the medium should not contain solid impurities or magnetic material , avoid blocking the float. According to the condition of the medium, the buoy can be cleaned periodically to remove internal impurities.
4, before use, should be calibrated with magnetic steel will be placed below the zero vane red, and the other set into silver white.
5. When the magnetic flap level gauge is put into operation, open the upper inlet valve first, then slowly open the lower inlet valve to allow the liquid medium to flow in smoothly to avoid the liquid medium with the float rising rapidly, causing the flap to turn over. Failure or turnover (in case of this phenomenon, you can use magnetic steel to correct).
6. Installation requirements for the top-mounted magnetic flap level gauge: For the top-mounted magnetic flap level gauge, the level gauge guard conduit and the main conduit must be kept vertical and on the same vertical line during installation. The float linkage cannot Bent, it must be straightened.
7. Anti-corrosion magnetic flap level gauge installation requirements: For 304-lined PTFE anti-corrosion magnetic flap level gauge, due to the unique sealing structure at the junction of the buoy and the flange, special tools are needed to assemble to ensure sealing. Reliability, it is forbidden to disassemble it after leaving the factory, otherwise the consequences will be at your own risk.
8. Installation requirements for ultra-long magnetic level gauges: For ultra-long magnetic level gauges (measurement range greater than 4m), the logistics and transportation costs are relatively high. Generally, a level gauge is produced in sections. The segmentation method has the following two forms, which can be determined according to the actual interface form of the customer's field device. Figure 1 is the form of a liquid level meter is divided into two sections, the installation of the first docking docking flange, in the docking operation can be appropriate to release the display panel, the number of support points according to the length of the liquid level meter to be set; The form of Fig. 2 is divided into two or several independent level gauges. This type of structure requires that the center lines of the two flanges in the middle of the tank are on the same level to achieve the continuity of the liquid level display.
