Continuous material flow detection (Flow / NoFlow)

FlowJam

Microwave sensor for contactless monitoring of material flow and detection of material clogging

The system operates with no contact in a process in which the material movement is detected by using the Doppler effect.

The FlowJam is a process-secure device, since the microwave technology used can penetrate material coating on the sensor and reliably detect the material movement behind it. If container walls, housings or pipelines are not metal, it is possible to measure from the outside.

  • Absolutely insensitive against material deposits
  • For any line diameter
  • With adapter, usable up to 220 °C and 20 bar
  • Compact (no separate electronics)
  • With ceramic mounting, usable up to 1,000 °C
  • Signalling through relay switching
  • Different sensitivity levels
  • Detection through all non-conductive walls
  • Can also be supplied with short housing and separate electronics
  • Detection of material clogging and material standstill
