Level

Feature (6)
  • New EDDL is guiding radar: interface level made easy
    Guided wave radar (GWR) level transmitters are ideal for challenging level and interface measurements on liquids, slurries and solids. A new breakthrough technology called electronic device description language (EDDL) integrates GWR level transmitters with intelligent device management software in a way not previously possible.
  • Interface level detection — what to consider
    Compared to standard level measurements in liquids, the detection and measurement of interfaces has its own particular challenges, leaving many interface applications without reliable level measurement. Most popular today are the electronic or non-mechanical solutions with no moving mechanical parts which offer much higher long-term stability and low-maintenance operation.
  • Increased plant safety puts focus on tank gauging
    The demand for safety technology in bulk liquid storage plants is increasing worldwide. This market trend can clearly be seen in tank gauging projects where Safety Integrity Level (SIL) requirements are now being incorporated.
  • Radiometric measurement — at home in extreme process conditions
    Radiometric measurement, also known as nuclear- or gamma-based measurement, is an extremely reliable and safe, non-invasive solution that is suitable for level limit detection, continuous level measurement, and density and interface layer measurement.
  • Level sensing for sewage lift stations
    The level sensor is a small but vital component in sewage lift or pump stations to maintain system integrity and avoid unwanted spillage.
  • Seeking self-adjusting instruments
    Modern process instruments incorporate a fair degree of intelligence used to optimise process variable accuracy and reliability, and can even undertake predictive maintenance. But they fail miserably in two critical aspects even when compared with technologies we use every day — self-adjustment and self-healing.
