  • The microwave barrier is a contactless measuring procedure
  • Can be installed in containers, pipelines, shafts or free-fall sections
  • Range is 0.1 … 25 m
  • If container walls, housings or pipelines are not metal, it is possible to measure from the outside
  • Can also be used under difficult conditions such as high operating temperatures and pressures with the help of a process-adapter
  • The use of microwaves also ensures a high level of insensitivity to any caking on the sensor window
