Regarding the issue that magnetic flap level gauges cannot measure media with low conductivity

I also came across it by chance on Baidu; I was completely stunned

Nonsense, we use it very well at the liquefied gas station, and it works well too in boiler drums

Upon closer thought, what is mentioned on the website seems to be the characteristics of an electromagnetic flowmeter.

Electromagnetic flowmeters cannot measure substances with low conductivity. . . And it says flow measurement above. . It seems to have been copied from somewhere without any changes

These mediocre websites are likely to mislead beginners

Low conductivity media can have an impact on the measurement of magnetic flap switches, but this impact is, first, not significant; second, it can be eliminated; third, it has a certain degree of randomness and does not occur frequently. Therefore, this issue is usually ignored. It can actually also be ignored. The claim is that low-conductivity media affect the measurement of magnetic flip plates: static charges often exist within low-conductivity media, and when these charges move or are released as the liquid changes, they can generate a magnetic field that in turn affects the state of the magnetic flip plates. In actual operating conditions, the liquid levels in contact with magnetic flip plates usually have a proper grounding system or other anti-static measures, so the possibility of static electricity causing problems is virtually non-existent. There is a speculation that the abnormality of one of the new magnetic flap switches is due to the effect of static electricity, but it is merely a speculation.
