In use, as a level instrument, magnetic level gauge is the most commonly used and easy to use level gauge, which can be used in various towers, tanks, tanks, spherical containers and boilers and other equipment. Media level detection.
However, in the on-site adjustment, it is sometimes found that floating floats are not special spirits. This situation is generally caused by improper installation. At this time, it should be noted that the center of the upper and lower flanges is not a line, is it perpendicular to the horizontal plane? In general, the included angle with the horizontal plane is not less than 87 degrees. If the deviation is large, the float patency may be affected.
1. The installation position of the magnetic flap level gauge should be avoided or separated from the inlet and outlet of the material medium to avoid the rapid change of the local fluid in the material fluid and affect the correctness of the level measurement.
Second, the installation of the magnetic flip level gauge must be vertical, in which the ball valve should be installed between the magnetic flap level gauge and the container lead to facilitate inspection and cleaning;
Thirdly, for level gauges of more than a certain length (normal type> 3 meters, anti-corrosion type> 2 meters), it is also necessary to add an intermediate reinforcement flange or ear climbing for fixed support, so as to overcome its own weight and increase its own strength. ;
Fourth, the debugging should first open the upper pilot valve, and then slowly open the following valve, so that the media smoothly into the main catheter (operation should avoid the media rapidly impact the float, causing fluctuations in the float series, affect the display accuracy), and then Close the lower pilot valve, open the drain valve, so that the liquid level in the main conduit is reduced, according to this method three times of operation, it is normal, and it can be put into operation (except for aggressive and other special liquids);
Fifth, the medium should not contain solid impurities or magnetic substances, so as to avoid blocking the float;
Sixth, according to the media, there is no regular cleaning of the main catheter to remove impurities;
VII. If the user uses the heat tracing circuit by himself, non-magnetic materials such as copper tubes must be used. Heating temperature is determined according to the medium condition;
8. The proximity of magnetic plate level gauge body to magnetic materials is not allowed, and fixing of wire is prohibited, otherwise it may affect the normal operation of magnetic plate level gauge.
