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.
