What is the principle of the magnetic float level gauge? What should be considered when choosing a magnetic level gauge?

The magnetic float level gauge is an instrument used in industrial measurement. I believe that many partners do not know the principle of the magnetic float level gauge and use it. Next, the editor of Huikeda Instruments will summarize the principles, installation and maintenance methods, and hope to help you.  The principle of magnetic float level gauge   Magnetic float level gauge is a new type of level gauge developed based on the principle of buoyancy and magnetic coupling, which can better indicate the actual height of the liquid level of the container. The usual error does not exceed 10 mm. When the liquid level of the measured container rises or falls, the magnetic float in the glass plate of the level gauge also rises and falls. The permanent magnet steel in the float is transferred to the magnetic column indicator through magnetic coupling, and then the red and white magnetic floats are driven to reverse. . When the liquid level rises, the magnetic float changes from white to red. When the liquid level drops, the magnetic float changes from red to white. The red and white dividing line of the indicator becomes the actual height of the liquid inside the container, and the liquid level is displayed clearly and accurately.  The principle of magnetic float level gauge   Installation and maintenance of magnetic float level gauge  1) The installation of the level gauge must be vertical to ensure that the airbag assembly can work freely up and down in the main tube.  2) Do not allow the magnetic conductor to approach the body of the level gauge. Otherwise, it will directly affect the reliable operation of the level gauge operation f.  3. After the level gauge is installed, it needs to be calibrated with a magnet, and it is turned over to make it red below the zero point and white above the zero point.  4) When the liquid level gauge is working, the liquid medium quickly rises with the float assembly. In order to prevent the anti-column from incomplete rotation and random rotation, first open the pull-down liquid pipe valve to allow the liquid medium to enter the main pipe smoothly. When this phenomenon occurs, the liquid level can be recalibrated after the liquid level is stable.5) Before leaving the factory, take the airbag assembly out of the tube of the main body of the level gauge, open the smoke exhaust flange at the bottom after the level gauge is installed, and then reinstall the airbag assembly into the main body tube to avoid transportation Damage to the airbag module. Note that the heavy head of the airbag module faces up and cannot be turned over. If the airbag module is installed in the main pipe at the factory, you only need to fix the airbag module in the main pipe with a soft card, and pull out the soft card during installation to avoid damaging the color airbag module during transportation.  The principle of magnetic float level gauge  6. According to the condition of the medium, the discharge flange can be opened regularly to clean the sedimentation material of the main pipe.   Factors to consider when choosing a magnetometer   (1) The physical and chemical properties of the measured medium, as well as measuring objects such as working pressure and temperature, setting conditions, and liquid level change speed;  ) Measurement and control requirements such as measurement range, measurement (or control) degree, display mode, on-site indication, remote indication, interface with computer, safety and corrosion protection, reliability and ease of construction.   Below, the editor summarizes the principle of the magnetic float level gauge and related installation and maintenance content. Thank you for reading. In addition, I hope this article can provide you with reference and help.
