Velocity measurement, material transport

SpeedFlow 2.0-Pipe

Velocity measurement in full cross-section version. Continuous velocity measurement in tube version for careful material transport. Measures in full cross-section.

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.

  • Continuous speed measurement of solids (powder, granules, dust ) in metal pipes
  • Measurement directly in the conveying stream / entrained flow
  • Measurement is completely independent of material
  • Sensor is made accordingly to the existing pipe diameter
  • Measurement without product contact
  • Plastic industry
  • Tobacco
  • Food
