Float level gauge
Thread Content
The existing Fisher DLC3010 float level gauge displays a constant value for the level; tapping on the tank wall can restore it to the normal value. In a little while, another value will remain unchanged. Experts, please give some advice – where is the problem? A solution is urgently needed! ! ! ! !
What medium is being measured? It seems that the high viscosity of the medium is causing the float to get stuck, limiting its upward and downward movement.
The tube inside is stuck; it’s probably because the medium is dirty. Try emptying it first. If that doesn’t work, remove it and clean the float – that should give good results
This is a typical manifestation of restricted up and down movement of the caisson. If it is newly installed, the reason is insufficient vertical alignment during installation, incorrect position of the sinker hook, or foreign objects inside the bucket ； If it was working well before, the reason is medium condensation or impurities in the medium causing condensation, along with foreign objects inside the tank.
It’s obviously a bit sluggish; check whether all the moving parts are flexible, whether the medium is clean, and whether there are any contaminants that prevent the float from moving up and down smoothly with the liquid...
It’s stuck; there are impurities or viscosity issues between the float and the rod
First, determine whether there is any blockage in the upstream or downstream valves; the only way to do this is by draining them. Be aware of the damage that media can cause to the environment and human health. Once it is confirmed to be unobstructed, operate the process using a hand valve or control valve to see if the liquid level changes accordingly No, just perform two-point calibration – it’s very convenient. I guess the problem here is that the medium is too dirty; there’s nothing wrong with the tube itself
It is also possible that the take over is too thin; when the viscosity of the medium is too high, the bypass pipe and the liquid tank cannot form a communicating vessel with an equal liquid level.
It might be that the medium is too dirty and has caused a blockage; in addition to any blockage in the inner cylinder, it’s also necessary to check whether there is a blockage at the blade area.
Is the installation vertical? Is the medium dirty? Is the float stuck?
