The solution to the measurement failure of the magnetic flap level gauge

The magnetic flap level gauge is composed of a measuring float, an indicator, a magnetic float, a connecting flange, and a drain valve. Since the functions of each component are interlocked, the failure of any one component may cause the instrument to fail and fail. normal work. 1. The actual liquid level rises, but the display panel has no response The magnetic flips (flip columns) in the scale flap have a magnetic coupling effect with each other, thus driving the flips to turn from white to red, and the junction of red and white is the actual height of the liquid level. If the flip sheet in the display panel does not respond, troubleshooting should be carried out from three aspects: (1) The magnetic float is stuck. Generally, the magnetic float is stuck for the following two main reasons: A. Due to the actual pressure on the site and the The pressure of the magnetic flap level meter does not match, that is, the purchase of the magnetic flap level meter did not communicate the technical parameters with the sales engineer. If the on-site pressure is too high, the magnetic float will be deformed and stuck in the main pipe; B. Due to the liquid medium It is viscous or prone to crystallize at a certain temperature, causing the float to get stuck. In order to avoid this situation, it is recommended to understand the on-site working conditions, and consider purchasing a lined magnetic flap level gauge when selecting an instrument. (2) The magnetic float loses its magnetism. If the magnetic float loses its magnetism, it is generally related to the high pressure in the working environment. It is recommended to confirm the pressure of the on-site working conditions, and then negotiate with the manufacturer to replace the new magnetic float. (3) The flip sheet (flip column) loses its magnetism. If this happens, it is probably because the magnetic flip sheet (magnetic flip column) has been used for too long, and replacement should be considered at this time. 2. In the process of liquid level display, the magnetic flip turns red and then turns back to white suddenly The chip turned from white to red and back to white, this is not due to the failure of the flip, but it needs to be solved by using a tool to space the display panel from the main tube a distance (about 5mm). 3. The scale of the display panel stays in a certain place and does not move. This phenomenon may be the same as phenomenon 1, that is, the magnetic float is stuck. You can first try the solutions used when the magnetic float is stuck. Another possibility is that the magnetic flip column may be damaged. For example, after the liquid level rises to one meter, the display is abnormal, but the actual liquid level has risen to two meters, that is, the display below one meter is normal, and the display panel after one meter The scale starts to stop in one place. If this phenomenon occurs, it is recommended to replace the entire flip sheet inside the display panel, or replace the flip sheet between one and two meters to try to solve it.
