Precautions for the use of magnetic flap level gauge

The magnetic flap level gauge is suitable for the liquid level measurement of the liquid medium in the container. In addition to the on-site display, it can remotely transmit 4-20mA electrical signals, and the level controller can output switch signals. The magnetic flap level gauge will encounter many problems in use, how to solve these problems? We need to pay attention to the following 4 points in our daily operations. Now let’s introduce the situation in detail: The first magnetic flap level gauge is suitable for liquid level measurement of liquid medium in the container. In addition to the on-site display, it can be transmitted remotely. 4~20mA electric signal, equipped with liquid level controller can output switch signal. The magnetic flap level gauge will encounter many problems in use, how to solve these problems? We need to pay attention to the following 4 points in our daily operations. Now I will introduce the situation in detail for you: 　　　　 First, the magnetic flap level gauge is the simplest direct-indicating level gauge that works under higher pressure. Its reliability and economy cannot be compared 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 a high degree of automation.　　　　 Second, when installing the magnetic flap level gauge, be sure to keep it in a vertical state. A ball valve should be installed between the magnetic flap level gauge and the container 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 of the float and affect the accuracy of the measurement.　　　　 Third, when selecting the installation location of the magnetic flap level gauge, it should avoid or stay away from the inlet and outlet of the material medium to avoid the rapid change of the material fluid in the local area, which affects the accuracy of the liquid level measurement. When debugging, open the upper valve of the guide pipe first, and then slowly open the lower valve to allow the medium to enter the main duct smoothly (in operation, avoid rapid impact of the medium on the float, causing the float to fluctuate and affect the accuracy of the display), and observe the magnetic red and white ball flipping Whether it is normal, then close the lower lead valve, open the drain valve, and let the liquid level in the main pipe drop. According to this method, operate three times, and it is normal, and then it can be put into operation. Fourth, when disassembling and cleaning the magnetic flap level gauge, you can open the bottom flange and take out the magnetic float for cleaning. After cleaning, you must pay attention to the installation of the magnetic float: the heavy end has the magnetic end upwards, and it must not be inverted. , Otherwise the level gauge will not work normally. Before use, the small balls below the zero position should be set to red with a correction magnet, and the other balls are set to white.
