1. The level gauge is adjusted normally, and it is found that the float is "absorbed" for a period of time in a certain position after it is put into use. This is mainly caused by the level gauge passing through the steel platform device and being spaced too close to the steel plate. Therefore, it is necessary to pay special attention to the distance between the wall of the level gauge connecting pipe and the cutting edge of the platform when passing through the steel platform device. According to the field application experience, this spacing of about 100mm can ensure that the magnetic float is not affected.

2. During the on-site adjustment, it will be occasionally found that the float is not sensitive enough to move up and down. This is mostly caused by improper level gauge devices, and it is necessary to pay attention to whether the center of the upper and lower flanges can be in a line and whether it can be perpendicular to the degree surface. Generally speaking, the angle between the plane and the degree plane should not be less than 87 degrees, if the deviation is large, it may affect the smooth movement of the float.

3. When the level gauge is put into use on site, special attention should be paid to opening the upper gate valve first, and then opening the lower gate valve. This is due to the fact that the bottom of the level gauge connecting pipe is equipped with a thrust spring to maintain the float, otherwise, the action of large differential pressure may break the float and cause the level gauge to be inoperable.

4. During the use of the level gauge, if the output signal produces frequent disturbances or interference pulses, it is necessary to check whether the signal cable shield can be firmly grounded, and whether the working connection resistance can meet the requirements. If the interference is still not completely resolved, a signal isolator can be used.

5. After the level gauge is put into use for a period of time, it is difficult for the float to float and the float is not sensitive. This is fundamentally due to the magnetic float being stained with iron filings or other dirt. You can drain the medium first, and then take out the float to eliminate the iron filings or other dirt on the magnetic float.

6. If the closed glass tube for on-site instruction is broken due to transportation or other reasons, the domestic glass tube can be replaced. But it's best to be able to vacuum. Also pay attention to whether the glass tube can be vertical, so as not to affect the indication of the indicator.

7. Pay special attention to the use of the level gauge, do not use a strong magnet to pull the float up and down outside the connecting tube to stop the inspection, otherwise it will cause the magnetization of the magnetic float and change the polarity, so that the magnetism of the float will be weakened, making it difficult to work normally.
