The magnetic flap level gauge is an on-site real-time indicating level gauge. Because of its large range, it can be made into a length of 1 meter or even 5 meters, so it is an ideal liquid level measuring instrument for large storage tanks. The magnetic flap level gauge has the advantages of good sealing and strong anti-leakage performance. At the same time, it is not affected by high temperature and high pressure occasions and strong corrosive media. It can accurately feedback the level of the liquid during the measurement process, because the reading is intuitive, safe and reliable , Is one of the most popular measuring instruments in the industrial field. Although the magnetic flap level gauge has many advantages, some problems will inevitably occur if the operation is improper. Today we will talk about the reasons for the low display of the magnetic flap level gauge.
We know that because the magnetic flap level gauge is simple and easy to use, it is widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection, shipbuilding, construction, food and other industries in the production process of liquid level measurement and control, even in the face of toxic , Harmful and strong corrosive media can also work normally. So, why do the magnetic flap level gauges with such strong adaptability often show the problem of low display? Is the magnetic flap level gauge improperly installed, or quality problems? In fact, there are two main reasons for the low display of the magnetic flap level gauge: man-made reasons and non-man-made reasons.
1. Man-made reasons:
The magnetic flap level gauge is also called the magnetic level gauge. Its working principle is based on the magnetic float as the sensing element. Through the lifting of the magnetic float, it generates a magnetic coupling with the magnetic flap, and then reflects the measured liquid through the display panel. Of the interface situation. From the above working principle of the magnetic flap level gauge, we know that the magnetic flap level gauge does not need to rely on energy to realize the measurement of the liquid level during the working process. The use of the flap level gauge is too long (more than five years), or it is accidentally demagnetized by magnetic materials on site, which will greatly affect the accuracy of its measurement. The most 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 level gauge. The level gauge is installed near the iron frame to avoid the low display of the magnetic flap level gauge.
2. Non-human reasons:
Magnetic flap level gauges are usually customized products, which are specially made according to different measurement conditions and different technical parameters corresponding to the measured medium. The magnetic flap level gauge has been tested for reliability before leaving the factory. If the display still appears to be low after excluding human causes, it is likely to be caused by the change (decrease) of the medium density itself.
The reason for the low display of the magnetic flap level gauge is not complicated. The reason why many instrument operators are at a loss after encountering this situation is because they are not familiar with its characteristics. Therefore, carefully reading and understanding the product manual is a problem. Very important step. (The article is excerpted from:, please indicate the source for reprinting.)
