Level Indicators

There are several types of Level Indicators. The two most predominant and ones that we provide are the following:

A Magnetic Level Indicator typically 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 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 predetermined 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 level gauge, the display elements, through the wall of the bypass chamber, are turned through 180°. This produces an increasing level from white to red; for a falling level from red to white. Thus the level gauge clearly displays the level of a vessel without power supply.

A Sight Glass Level Indicator is a glass gauge, in which the main element 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 are already integrated, the valve heads and process connections. Drains or vents 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 made from borosilicate glass are used for glass gauges. For steam applications, the glasses can be used up to 243 °C, with a mica design to 300 °C. For other media, temperatures up to 300 °C are possible, in special cases up to 374 °C. The use of mica is needed for specific applications.
