For continuous level indication, level indicators are utilized. The functional idea is based on a magnet coupled to a float transferring the level to an indicator bar made of magnetic rollers or flaps without the need for an additional supply voltage. Different magnetic switches and level sensors can also be added as extra accessories.
Individual design and corrosion resistant materials make the products suitable for a broad range of applications
Chemical, petrochemical industry, oil and natural gas extraction (on- and offshore), shipbuilding, machine building, power generating equipment, power plants
Process water and drinking water treatment, food industry, pharmaceutical industry
Process- and system-specific production
Operating limits: - Operating temperature: T = -196 ... +450 °C - Operating pressure: P = vacuum to 400 bar - Limit density: ρ ≥ 340 kg/m3
Wide variety of different process connections and materials
Mounting of level transmitters and magnetic switches possible as an option
The magnetic level gaugemodel BNA consists of a bypass chamber, which, as a communicating tube, is connected laterally to a vessel via at least 2 process connections (flanged, threaded or welded). Through this type of arrangement of themagnetic level gauge, the level in the bypass chamber corresponds to the level in the vessel. The float with a built-in permanent magnetic system, which is mounted within the bypass chamber, transmits the liquid level, contact-free, to the magnetic display mounted to the outside of the bypass chamber. In this are fitted, at 10 mm intervals, two-coloured plastic rollers or stainless steel flaps with bar magnets.
Through the magnetic field of the permanent magnetic system in the float of themagnetic level gauge, the display elements, through the wall of the bypass chamber, are turned through 180°. For an increasing level from white to red; for a falling level from red to white. Thus themagnetic level gauge clearly displays the level of a vessel without power supply.

The model UTN top-mounted level indicator consists of a measuring chamber, a float with guide rod and a magnetic system. Mounting onto the vessel is made via appropriate process connections (flange, thread). The permanent magnetic system, which is connected to the float via a guide rod, transmits the liquid level measured in the vessel by the float, contact-free, to the magnetic display mounted to the outside of the measuring chamber.
In this magnetic display there are red/white plastic rollers or stainless steel flaps with bar magnets fitted at 10 mm intervals. The magnetic rollers or flaps are turned 180° through the walls of the measuring chamber. For an increasing level from white to red; for a falling level from red to white. Thus the magnetic display indicates the level of a vessel as a red column, without power supply.
