Continuous material flow detection (Flow / NoFlow)

FlowJam

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

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.
