Description

The main element of the glass level gauge is the gauge body. Incorporated into this gauge body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses.

Onto the gauge body are mounted, or are already integrated, the valve heads and process connections. Drain or vent are also possible.

Compact version with side pieces, model LGG-E

The glasses and/or mica shields 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 to 243 °C [469.4 °F], with mica design to 300 °C [572 °F]. For other media, temperatures to 300 °C are possible, in special cases to 374 °C [705.2 °F]. The use of mica is needed for specific applications.
