Magnetic level gauge There are many problems in use. How to solve these problems? We need to pay attention to the following four points in daily operation. Now we will introduce the situation in detail:
1. When selecting the installation position, the inlet and outlet of the material medium should be avoided or kept away from, so as to avoid the rapid change of the local area of the material fluid, which will affect the accuracy of the liquid level measurement. During commissioning, the upper pilot valve shall be opened first, and then the lower valve shall be opened slowly, so that the medium can enter the main pipe smoothly (the medium shall not impact the float rapidly during operation, causing dramatic fluctuation of the float, affecting the display accuracy), observe whether the magnetic red and white ball is normal, then close the valve of the lower lead pipe, open the drain valve, and let the liquid level in the main pipe drop, and operate according to this method Three times, it is normal, and it can be put into operation.
2. Right Magnetic level gauge When disassembling and cleaning, the bottom flange can be opened and the magnetic float can be taken out for cleaning. After cleaning, attention must be paid to the installation of magnetic float: the heavy end with magnetic end is upward, and it is not allowed to flip it, otherwise the level gauge will not work normally. For the following, use the red ball to correct.
3. It is the simplest direct indicating level instrument working under high pressure. Its reliability and economy are incomparable with other instruments. As a basic liquid level indicator, it is indispensable in the simplest liquid level measurement occasions and large-scale engineering projects with high degree of automation.
4. During installation, the vertical state must be maintained. A ball valve should be installed between the magnetic flap level gauge and the vessel lead pipe to facilitate the maintenance, disassembly and cleaning of the level gauge. The liquid medium to be measured should not contain solid impurities or magnetic substances, otherwise it is easy to cause jamming to the float and affect the accuracy of measurement.
