Vortex flow sensor Type VVX15

 

Product description

Possible areas of application Vortex flow sensor Type VVX 15

SIKA VVX15 flow sensors are used for measuring water flow at low and medium measurement ranges.
One such application area is heating systems.

 

Description

Function
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.
