操作指南 Magnetic Flip Level Gauge Operation Guide
1. When debugging, first open the upper lead valve, then slowly open the lower valve to allow the medium to enter the main pipe smoothly (the medium should be avoided from impacting the float sharply during operation, which will cause the float to fluctuate and affect the display accuracy). Observe the magnetic red and white balls Whether the overturn is normal, then close the lower inlet valve, open the drain valve, and lower the liquid level in the main conduit. According to this method, it is normal for three times to be put into operation (except for special liquids such as corrosive); 2. Occasionally, clean the main conduit and remove impurities from time to time; 3. For liquid level gauges that exceed a certain length (common type> 3 meters, anti-corrosion type> 2 meters), the intermediate reinforcement flange or ears are required to increase the fixed support to increase Strength and overcome its own weight; 4. The installation position of the magnetic flap liquid level gauge should avoid or stay away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid and affect the accuracy of the liquid level measurement; When there are remote transmission supporting instruments, the following should be done: the remote transmission supporting instruments should be close to the main pipe of the level gauge and fixed with stainless steel hoop (iron is prohibited); The zero position of the supporting instrument should be on the same horizontal line as the zero indication of the level gauge; the sensing surface on the remote supporting instrument should face and close to the main duct; the connection between the remote supporting instrument and the display instrument or industrial computer is the most Lay the protective tube separately or use a shielded two-core cable to lay it. After laying the cable entry hole of the junction box, it must be sealed well to prevent the invasion of remote transmission equipment from working due to the intrusion of rain, moisture, etc. After the junction box is overhauled or debugged, Cover it in time.

指示器安装在桶槽外侧或上面,用以指示和控制桶槽内的封形式可根据需要加装排污阀。 The magnetic flap liquid level indicator is installed outside or above the bucket tank, which is used to indicate and control the seal form in the bucket tank. A drain valve can be added as required. The connection flange can be a control instrument for customizing the liquid level height. The indicator consists of magnetic color chips. When the magnetic floating ball in the body tube rises with the liquid level, the color film is flipped to display the liquid level height. It is also possible to install a magnetic switch or remote transmitter on the body tube to output a switch signal or an analog signal. It is suitable for high temperature, high pressure, corrosion resistance and other occasions. It can be displayed and controlled remotely. The body pipe is made of seamless steel pipe, and the connecting pipe is welded with pull holes, and there is no scratch inside. The installation method can be side or top, and the lower end of the body is sealed.

维护:1. 液位计筒体内不应有固体杂质和磁杂质进入,以免对浮子造成卡阻及减弱浮力。 Maintenance of magnetic level gauge : 1. There should be no solid or magnetic impurities in the level gauge barrel to avoid blocking the float and weakening the buoyancy. 2. According to the condition of the medium, the main pipe can be cleaned regularly to remove the impurities in the pipe. 3. After cleaning the level gauge or replacing the float, open the drain flange. When installing the magnetic float, pay attention to the magnetic end of the heavy end facing up. Do not install it upside down. 4. For low-temperature and liquefied gas special products The main body of the level gauge adopts a vacuum jacket for heat insulation. Be careful not to damage the jacket during installation and use, so as not to affect the product quality.
