A company uses our guided wave radar level meter, model RD702, to measure acetic acid, at room temperature.
Acetic acid is an organic compound, a mono-organic acid, which is the main component of vinegar. Pure anhydrous acetic acid is a colorless hygroscopic liquid, which turns into colorless crystals after solidification. Its aqueous solution is weakly acidic and highly corrosive.
In the process of use, radar jumping, into the liquid dead value of the situation, our after-sales engineers checked and found that the guide wave radar level meter cable length is 15 meters, the actual height of the site is 14.5 meters, and is measured in the guide wave tube, the installation base has some tilt, resulting in interference signal, thus causing the radar level meter jumping dead value.
The solution from the after-sales engineer was to add a tetrafluoro bracket to prevent the cable from touching the wall of the pipe, and to tie up the long part of the lower end of the cable with a tie to prevent it from touching the bottom of the tank so that the problem was solved.
