Faults 1. Locally, the normal remote transmission has an abnormal cause. In general, there are many reasons for this failure. The following are the more common reasons: 1. Resistance welding. 2. The pressure exceeds the rated value, causing the switch to be damaged. 3, the domestic glass tube reed switch fragile dry spring tube short circuit or open circuit, resulting in abnormal transmission. 4. In the case where the temperature of the medium is too high, the metal foil is thermally expanded, and the metal contact gap of the reed switch is small, and the closed state is likely to occur.

Fault 2, remote transmission and magnetic flaps do not move. This kind of fault phenomenon is usually caused by the abnormality of the float. There are mainly two kinds of performances: First, due to the damage of the float, the indication of the display panel is incorrect, resulting in the magnetic flap level gauge. The reasons for the damage of the float are usually as follows: 1. Because the strength of the float is not designed correctly, it will become concave and sag when subjected to pressure. 2. The weld is not welded or leaked, causing the weld to crack when the float is under pressure and the float to enter the water. 3. The float is demagnetized due to its long use time or long-term use at high temperatures, and it cannot be used normally. 4. The loosening of the magnetic steel in the float prevents the float from working properly.

Fault 3: The reason why the float panel is stuck, causing the display panel to be inaccurate causes the float in the magnetic flap level gauge to be stuck. The following are common ones: 1. The ambient temperature is too low, and the float is frozen due to the medium. Can't move properly. 2. The installation angle of the float is less than 87 degrees. Due to the tilt of the float, the up and down movement of the float is affected. 3. The float absorbs iron filings or other dirt due to its own magnetic properties, causing the float to be prevented from moving normally by the card. 4. Because the seal is not tight, the float is stuck by the infiltrated impurities, so that the float cannot rise or fall.

The so-called cause failure has been solved in half. Through the above analysis of the common faults of the magnetic flap level gauge, we basically find a way to deal with the problem, we can deal with it according to the faults and their causes.
