Bypass level indicator

bypass Niveauanzeige

In a wide pressure range (vacuum up to 250 bar) as well in the temperature range from-200 °C to 400 °C the bypass­ level indicator is used for reliable measurement, switching and transmission. The float-mounted permanent magnet affects the red/white display roles of a flap track through the pipe wall that is displaying a conspicuous red display area analog to the fluid level.
The magnetic stabilization of each display role ensures a perfect vibration resistance of the display system.
