PYM-UZ
Simply the best magnetic level meter.

Hydro-Air PYM-UZ Magnetic Level Meter is using the bypass pipe and tank (or container equipment) to form a communicator to ensure that two liquid level is highly consistent. Under the action of liquid buoyancy, when the liquid level rises and falls, the liquid level float rises and falls accordingly.
Besides, under the action of magnetic coupling, the permanent magnetic steel in the float drives the magnetic red and white turning beads to turn 180 degrees, so that the liquid level can be clearly and intuitively indicated by the scale of red and white dividing line in the turning plate box.
