Non- Contact Radar Level Sensor


The ideal sensor for non-contact level measurement in simple applications where a high degree of protection is required. It is particularly suitable for use in water treatment, pumping stations and rain overflow basins, for flow measurement in open channels and level monitoring. In bulk solids the sensors are used in small bulk solids silos or open containers.


  • Exact measurement results independent of medium, process and environmental conditions
  • High accuracy and wide measuring range
  • Maintenance-free operation due to non-contact 80 GHz radar technology
