The magnetic flap level gauge is a real-time indicator type liquid level gauge. Because of its large range, it can be made into a length of 1 meter or even 5 meters. Therefore, it is an ideal liquid level measuring instrument for large storage tanks. The magnetic flap level gauge has the advantages of good sealing performance and strong anti-leakage performance. It is not affected by high temperature and high pressure occasions and strong corrosive medium. It can accurately feedback the liquid level during the measurement process, because the reading is intuitive, safe and reliable. It is a popular measuring instrument in the industrial field. Although the magnetic flap level gauge has many advantages, it is inevitable that some problems will occur if the operation is improper. Today we will talk about the reason why the magnetic flap level indicator is low. We know that because the magnetic flap level gauge is simple and easy to use, it is widely used in liquid level measurement and control in the production process of electric power, petroleum, chemical, metallurgy, environmental protection, shipbuilding, construction, food and other industries, even if it is toxic. Harmful, highly corrosive media can also work properly. Then, why is the magnetic flap level gauge with such a strong adaptability often showing a low display problem? Is the magnetic flap level gauge improperly installed or has a quality problem? In fact, there are two main reasons for the low display of magnetic flap level gauges: human causes and non-human causes. First, human reasons: The magnetic flap level gauge is also called magnetic level gauge. Its working principle is that the magnetic float is used as the sensing component. Through the lifting and lowering of the magnetic float, magnetic coupling is generated with the magnetic flip, and then the liquid to be tested is reflected by the display panel. The interface situation. According to the above working principle of the magnetic flap level gauge, we know that the magnetic flap level gauge does not need to use energy to measure the liquid level during the working process, because the "magnetic force" is its *key driving source, if the magnetic If the flap level gauge is used for too long (more than five years), or if it is demagnetized by a magnetic substance in the field, it will greatly affect the accuracy of the measurement. The common situation is that the display is low. Therefore, in order to make the magnetic flap level gauge work reliably, we should minimize the interference of human factors on the magnetic flap level gauge, avoid the magnetic field appearing near the working environment of the magnetic flap level gauge, and do not use the magnetic flap The level gauge is installed near the iron frame to avoid the low display of the magnetic flap level gauge. Second, non-human reasons: The magnetic flap level gauge is usually a customized product, which is specially made according to different measurement conditions and different technical parameters corresponding to the measured medium. The magnetic flap level gauge is tested for reliability before leaving the factory. If the display is still low after eliminating the human cause, it is likely that the medium density itself has changed (smaller). The reason why the magnetic flap level indicator is low is not complicated. The reason why many instrument operators are overwhelmed after encountering this situation is because they are not familiar with their characteristics, so carefully read and understand the product manual is a Very important step.
