  • Detects solid flows of all types for material movement
  • Operates with no contact, using microwaves in a process in which the material movement is detected by using the Doppler effect
  • 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 as well as in dust ex-zone 22 with the help of a process adapter
