Analysis on four kinds of abnormal display of side mounted magnetic float liquid level meter

In many liquid level meters, the side mounted magnetic float liquid level meter also occupies a place. It is mainly composed of guide rod, floating ball and other components, and works on the principle of magnetic force and buoyancy. Usually, people will install the tested container on the top and connect it with flange. When the liquid level in the container changes, the float will also change, so that we can accurately grasp the position of the liquid through the float.

However, in the process of using the side mounted magnetic float liquid level meter, there will occasionally be a small problem, such as abnormal indication, some interference caused by the surrounding magnetic field, or the floating ball can not move, etc,

1. The index value is in the state of "Zui maximum"

According to the investigation of our staff, this kind of problem often appears in the atmospheric workshop. When we find that the counterweight of the float ball in the side mounted magnetic float liquid level meter is at the low point of * *, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument, so the value is Zui maximized. For this kind of problem, we speculate that it may be caused by the false appearance of floating ball damage in the instrument. Of course, do not panic when there is a problem. Replacing the float ball in time can solve this kind of problem.

2. The floating ball does not change with the liquid level.

When we find this situation, the usual problem is the floating ball in the level gauge, but it is not damaged. It may be caused by the floating ball falling off. In view of this situation, the staff only need to check and re install the floating ball in time.

3. The index value is generally low

There are many reasons for this situation. Sometimes, when the float falls off, it will cause this situation. In addition to the fracture of the connecting rod between the floats, the damage of the float pointer or the float head may also occur. Therefore, when we solve this problem, careful examination is very important.

4. The transmitter suddenly has no signal

If there is an error, you should check whether there is a voltage signal in the circuit. If not, the power supply of the measuring element is normal. When the measurement shows that there is no exception, the polarity is not reversed, and there is no power output current conversion part, the tool head must be damaged. The staff can repair the instrument or replace the head in time to solve this problem.

Above, we will explain some possibilities and solutions of side mounted magnetic float liquid level meter display failure from four directions. Instrument failure is not terrible. Timely maintenance and routine maintenance, side mounted magnetic float liquid level meter will be used on us for a long time.
