As a liquid level measuring instrument, the magnetic flap level meter is commonly used for the detection of liquid level in various towers, tanks, tanks, spherical vessels and boilers and other equipment. Due to its simple structure, eye-catching indication, accurate measurement, low maintenance and many other advantages, it has been quite popular with users, widely used in petroleum, chemical and other fields of liquid level measurement occasions. In addition, according to the characteristics of different working conditions and user needs, the magnetic flap level meter can also achieve high sealing, anti-corrosion, large range, for complex working conditions of the liquid level measurement. Like the extra-long magnetic flap level meter can be used in the storage tank is very long, the need to measure a large range of working conditions. However, if installed improperly, it will affect the normal work of the instrument, so how should the magnetic flap level meter for large storage tanks be installed?

In the introduction of large storage tanks in the ultra-long magnetic flap level meter how to install, we first talk about the practice of commonly used to the ultra-long magnetic flap level meter occasions and treatment methods. Long magnetic flap level meter is usually used in the measurement range of more than 4 meters, but the long magnetic flap level gauge invariable installation and transportation, at this time often magnetic flap level meter for segment production. Segment production and installation, not only does not affect the measurement effect of the magnetic flap level meter, but also very convenient product transportation and installation, reducing the cost of transportation and installation costs.

　　Generally speaking, the float of a magnetic flap level meter is divided into 2 or more sections and the flanges are used to connect the floats together. The display panel is truncated here, but this does not affect the observation and judgement of the level of the entire magnetic flap level meter. Due to the long size of the connected magnetic flap level meter, additional support flanges or other support structures are required in the middle of the installation to ensure that the extra long magnetic flap level meter is secure and reliable, as shown in the diagram above.

In order for field instrument operators to better use the extra-long magnetic flap level meter, the extra-long magnetic flap level meter installation considerations are summarised as follows:

　　1, in unpacking the box should be careful, take out the segments of the magnetic level gauge, will be placed on a flat ground or platform. The flange of each section will then be bolted together, and the inner hole of the flange on both sides of the docking requires a smooth transition, while ensuring that the overall magnetic flap level meter is vertical when docking, so that the float can move smoothly up and down in the float.

　　2, the upper and lower connection flange of the magnetic flip-plate level meter and the upper and lower fixed flange of the storage tank are connected, generally between the upper and lower connection flange and the storage tank need to be equipped with additional shut-off valves, in order to cut off the magnetic flip-plate level meter when the instrument is overhauled or has a fault. At the same time, in the middle part of the magnetic level transmitter need to add support flange, to increase the strength and to overcome its own weight, to ensure that the installation is solid and does not shake. According to the length of the magnetic flap level meter to determine the number of intermediate support points.

3, open the bottom flange, in loading the magnetic float, should pay attention to the heavy end with the magnetic end up, to avoid the installation of the reverse.

　　4, in order to avoid the normal work of the magnetic flip-plate level meter is affected, in the magnetic flip-plate level meter around the barrel, not allowed to have iron or magnet near, also disable iron clamps.

　　5, the magnetic flip-plate level meter float should not be solid impurities into the barrel, so as not to cause blockage of the float. According to the media, increase the filter, and regularly clean the float, to remove internal impurities.

　　6, the magnetic flip-plate level meter after installation, need to be corrected with a magnet, so that the zero above the display silver-white, zero below the display of red.

　　7, the magnetic flip plate level meter into operation, should first open the upper lead pipe valve, and then slowly open the lower lead pipe valve, so that the liquid medium flows smoothly, to avoid the liquid medium with the float rising rapidly, resulting in flip flop flop or flip failure. If this phenomenon is encountered, use magnets for correction.

　　From the above installation requirements, the installation and maintenance of large storage tank extra-long magnetic flap level meter is very delicate, we only skilled and in strict accordance with the above operating specifications for correct installation, regular inspection and maintenance, in order to make the magnetic level indicator work more stable, more durable.
