Our range of VLIs can provide an optimal solution for almost any level measuring and control application. For most applications, a suitable indicator can be configured from standard, modular components. Special solutions are frequently needed for unusual operating and installation conditions. We cover an extremely wide range of special level instrumentation requirements. If necessary, the standard interfaces can be adapted to match the requirements of customer’s control systems.


  • Very wide operating range: Vacuum to 500bar pressured tanks, up to 0.3g/cm3 liquid densities, 77K to 673K operating temperatures
  • Available with Level Indicator, Level Switch and Level transmitters for remote monitoring and control
  • The operating principle is based on the use of permanent magnet system ensuring safe and reliable activation of visual indication elements or transducers
  • Magnetic elements used can withstand high temperatures with negligible degradation of magnetic flux.
  • Lightweight and hermetically sealed floats ensure smooth usage for dirty and high viscous liquids over large indication ranges.
  • Closed and Open floats are available for various pressure ranges
