Vortex flow meter VVX20

volumefor waterDN20 - 3/4"

No mechanical wear. Flow sensor without moving parts for water. Completely encapsulated piezoceramic sensor for vortex detection. No direct contact with the medium. QuickFasten - quickly and safely mountable plug connection (Poka Yoke). Tool-free assembly, positive-locking connection The SIKA VVX QuickFasten is used for the flow measurement of water at low and medium measuring ranges. It is used, e.g, in heating technology. Behind a flowed-around bluff body, counter-rotating and mutually offset vortices arise. The vortices detach at the edges of the bluff body and form a Kármán vortex street in the flow. The distance between the individual vortices is constant. The frequency at which the vortices flow past a sensor depends on the flow velocity and is proportional to the flow rate. The sensor detects the vortices, which are converted into an electrical frequency signal.
