Level Indicators

Fluid Controls can supply a complete range of WIKA Level Indicators. Their superior range of Level Indicators are designed for continuous level indication without power supply and are ideal for applications involving processing water and drinking water treatment.

Model LGG Sight Glass Level Indicator

The main element of the sight glass level indicator is the body. Incorporated into this body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses. Onto the body are mounted, or already integrated, valve heads and process connections. Drain or vent are also possible.

The glasses and/or mica discs (as well as the seals) are fitted, secured and sealed with the aid of U-bolts and covers or pressure frames. Glasses from borosilicate glass, in accordance with DIN 7081, are used. For steam, the glasses can be used up to 243°C, with mica design to 300°C. For other media, temperatures up to 300°C are possible and in special cases up to 374°C. The use of mica is needed for specific applications.

Model BNA Bypass Level Indicator

The bypass level indicator 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, 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, 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 bypass level indicator clearly displays the level of a vessel without power supply.
