In fact, most factories in the industry now need to equip their equipment with one or more sets of level gauges during production and operation, that is, level measuring instruments, but because there are many kinds of level gauges on the market, and factory equipment There are many kinds of measurement objects, including different physical properties, different chemical properties, different functional requirements, different installation methods, different measurement methods, etc., which will affect the different level gauges selected by the user. Liquid level gauges include radar, glass tube, float, magnetic flap, heavy hammer level gauge, quartz tube, boiler, ultrasonic, etc. Here we mainly talk about what to pay attention to when installing and using the magnetic flap level gauge , In order to play the role and effect that it should have.1. The magnetic flap level gauge uses a magnetic float composed of high temperature resistant and magnetic magnetic blocks as the main component to participate in the measurement. Because of its magnetism, there should be no magnetic equipment around the magnetic flap level gauge. Or things that interfere with the magnetic performance, otherwise it will affect the normal performance of the magnetic float, and then lead to errors in the liquid level. Therefore, the surrounding environment where the magnetic flap level gauge is installed is very important.2. At the beginning, we said that there are different installation methods for level gauges, so when installing the magnetic flap level gauge, whether you choose top-mounted (vertically inserted into the tank) or side-mounted (side flange butt joint) , It is necessary to open holes in the tank and other equipment in advance. We know that the magnetic flap level gauge is flange-mounted, so the holes on the equipment in advance should be made according to the manufacturer’s flange standards, or you must purchase a matching flange with the manufacturer; or communicate in advance to let the manufacturer customize and follow The same specifications of flanges for opening holes on your own equipment are also possible.The magnetic flap level gauge is composed of the main body, flap box (composed of red and white two-color magnetic flaps), float, flange cover, etc., and is used for liquid level measurement of various liquid containers. It can be used in high temperature, explosion-proof, anti-corrosion, food and beverage and other occasions, as liquid level display or remote display and control.1. No magnetic material is allowed around the magnetic flap level gauge body, and iron wire fixation is prohibited, otherwise it will affect the normal operation of the magnetic flap level gauge; 2. Magnetic materials, such as copper tubes, etc. The heating temperature is determined according to the condition of the medium; 3, the installation of the magnetic flap level gauge must be vertical, and a ball valve should be installed between the magnetic flap level gauge and the container lead pipe for easy maintenance and cleaning; 4, the medium should not contain solid impurities Or magnetic material, so as not to cause jamming of the float; 5. Before use, the small ball below the zero position should be set to red with a correction magnet, and the other balls are set to white; 6. Open the bottom flange and install the magnetic float; 7. When debugging, you should first open the upper lead valve, and then slowly open the lower valve to allow the medium to enter the main pipe steadily, observe whether the magnetic red and white ball flips normally, 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 it three times, and it is normal, and it can be put into operation (except for special liquids such as corrosive); 8, according to the medium condition, clean the main conduit from time to time to remove impurities; 9, for more than a certain length (normal type＞3 Meters, anti-corrosion type> 2 meters) level gauge, need to add a middle reinforced flange or ear pan as a fixed support to increase the strength and overcome its own weight; ：The remote transmission supporting instrument should be close to the main pipe of the level gauge and fixed with stainless steel hoop (iron is prohibited); the sensing surface of the remote transmission supporting instrument should face and close to the main pipe; the zero position of the remote transmission supporting instrument should be in line with the liquid The zero position indicator of the potentiometer is on the same horizontal line; after the wiring hole of the junction box is laid, it is required to be well sealed to prevent rain, moisture, etc. from intruding the remote transmission supporting instrument can not work normally. The junction box should be covered in time after the overhaul or debugging is completed. superior.
The above two points are only what needs to be paid attention to when installing, using and debugging the magnetic flap level gauge, precautions for selection and precautions for later use and maintenance.
