FlowJam S –
Material flow monitoring
Microwave detector for contactless monitoring
of material flows for “flow” or “no flow”
- Absolutely insensitive against material deposits
- For any line diameter
- With adapter, usable up to 220 °C and 20 bar
- With ceramic mounting, usable up to 1,000 °C
- Usable in dust ex-zones
- Detection through all non-conductive walls
- Can also be supplied as compact device with integrated electronics
- Detection of material clogging and material standstill

Use / Function
The FlowJam S detects solid flows of all types for material movement.
A differentiation is made between the following switching states:
- Material flow
- Material clogging / standstill or empty pipe
The system operates with no contact, using microwaves in a process in which the material movement is detected by using the Doppler effect. The FlowJam S is an especially process-secure device, since the microwave 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. The FlowJam S can also be used under difficult conditions such as high operating temperatures and pressures as well as dust and gas ex-zones with the help of a process adapter.
Mounting and Installation
The FlowJam S can be easily installed in the following ways:
- Screwing into a 1 ½-inch-threaded connection
- using a DN 40 flange as well as
- using a pipe clamp or other holding bracket
options are German, English or French.
