The model BMD magnetic displays are used in combination with bypass level indicators for the display of levels. A magnetic system built into the float transmits the liquid level, contact-free, to the externally mounted display. In this are fitted, at 10 mm intervals, red/white plastic rollers or stainless steel flaps with bar magnets. Through the directional magnetic field of the permanent magnetic system in the bypass float, the magnetic rollers or flaps, through the wall of the bypass chamber, are turned through 180°.

With this functional principle of the magnetic display, the level of a vessel is indicated as a coloured column, without power supply. An integrated T-slot serves for the fastening of further attachment parts such as scales, sensors and switches. For selecting the optimum magnetic display (plastic rollers/stainless steel flaps, case, scale, measuring range etc.) we offer application-related technical advice.
