Description
The magnetic level gauge model 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 the magnetic 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 the magnetic 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 the magnetic level gauge clearly displays the level of a vessel without power supply.
Applications
Continuous level indication without power supply Indication of the level proportional to height 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 industrySpecial features
