Magnetic level gauges work on the principle of communicating vessels, therefore the level in the measuring chamber will be the same as the level in the vessel.
The measuring chamber is fitted with a float, which has a magnet
inside. The float with magnet will float on the medium and the magnet in the float will turn the flaps of the indicating rail.
The float in the measuring tube is standard not pressurized and has no magnetic or mechanical guidance. This construction makes the float less dangerous than a float which is standard pressurized.
Each flap in the indicating rail is fitted with a permanent magnet
which makes this level gauge unaffected by shocks, vibrations
and high temperatures. Also moisture and / or an aggressive
environment are no problem for this level gauge.
