KLINGER magnetic level gauge

Application

KLINGER MLG is a magnetic level gauge designed for reliable and visual level measurement in vessels, tanks, and boilers. The magnetic level gauge is used in both standard and demanding industrial applications where high requirements for safety, operational reliability, and clear readability apply.

The magnetic level gauge is suitable for oil, water, as well as toxic, aggressive, and explosive media, and can be used at both very high and very low temperatures. The solution is also used for steam boilers, where stable level indication at high pressure is essential.

KLINGER MLG can be supplied with magnetic switches and/or a level transmitter, making the magnetic level gauge suitable for visual monitoring, signalling, and integration into process and control systems. The robust, vibration‑resistant display ensures very clear and safe reading, even under demanding operating conditions.

Magnetic level gauges & accessories

A measuring chamber designed as a parallel tube is placed on the outside of the tank with the level to be measured. A magnetic float is placed in the measuring chamber. This will follow the liquid’s surface so that the tank contents become visualized, by allowing the magnet to affect the roller scale mounted outside of the measuring chamber. The float’s position thus appears on the outside of the pipe, on a scale roller, typically via a color change. Bypass systems are available in lengths from 150mm up to 25.000mm, and can be equipped with external switches and transmitters.
