FlowJam A –
Material flow monitoring
for hose lines

FlowJam A is a sensor which has been specially developed for monitoring the flow of solids conveyed by hose lines. The system can be applied to hose lines made of non-conducting materials such as plastic or rubber with external diameters of between 2 and 10 mm.
The hose line is inserted into the sensor for measuring.

What do you want to do?


FlowJam A detects streams of solids of all types flowing at a minimum speed of 0.1 m/s through
the detection area.

The detection is independent of the direction of flow through the Doppler effect evaluation system.
The flow of material through non-metallic pipelines is displayed by two switching states on the output relay.

The sensor differentiates between the two switching states:
•      Material flow
•      Material blockage or standstill.


A complete measuring device consists of the sensor and a transmitter which powers the sensor and provides a switch output.

The control elements for the start-up procedure are found on the FlowJam A’s DIN rail electronics. Both the switching sensitivity
and the response delay can be set.


Electrical connection

A 2-core cable is required to connect the sensor to the transmitter.
The length must not exceed 300 m.
The sensor is equipped with an M12 connector (including a mating plug).
