How to repair an inaccurate magnetic flap level gauge – simple troubleshooting methods
Close the manual valve, drain the fluid, unscrew the flange below, remove the float ball, and check to see if the inside of the cylinder is dirty.
A flap level gauge is simply a communicating tube; if the zero point is set correctly, there should be no errors. Primarily, the designed density of the float should match its actual density.
The operation steps are generally in accordance with those described by ylb913; the most common issue is that the tube becomes dirty, which causes the float to get stuck and leads to inaccurate readings； It is also necessary to check whether the float is damaged; there have been cases where material entered the float as well.
If I use a magnet to bring the liquid level back to zero, why doesn’t the float of the level gauge turn red at all?
Does that mean the float is stuck inside the buoy?
Close the manual valve, vent the system, unscrew the flange below, and remove the float to check whether the inside of the cylinder is dirty. It is also necessary to inspect the integrity of the float; be careful not to install the float in the wrong orientation during reinstallation

Close the level gauge’s one-way valve, open the vent and drain valve of the level gauge to empty it; then remove the flange at the bottom and take out the float to check whether the inside of the tube and the float are dirty – if so, clean them. Use a magnet to turn the entire level gauge panel white. It is also necessary to check the integrity of the float; take some material from the container being tested and place the float inside to see if it can float on top of it Do not install the float ball in the reverse direction during reinstallation.
