Vortex Flow Sensors

5 Star Google Business Review Rating

Alternate vortices rotating in opposite directions are generated behind a bluff body immersed in a flow. The vortices detach from the edges of the bluff body and form a Kármán vortex street in the fluid stream. The distance between the single vortices is constant. The frequency of the vortices flowing past a sensor depends on the flow rate and is proportional to the flow. The sensor detects these vortices which are then converted to an electrical frequency signal.

Our meters have flow ranges between 2 and 150 l/min.

Some of the advantages of this measuring principle:

Almost free pipe cross section > low pressure drop
Wide range of applications in terms of pressure, temperature and density
Independent of the conductivity of the medium
High long-term stability / no zero drift
