Vortex flow meter VVX32

volumefor waterDN32 - 1"1/4

No mechanical wear. Flow sensor without moving parts for water. Completely encapsulated piezoceramic sensor for vortex detection. No direct contact with the medium. Highest stability and performance. Robust brass or stainless steel housing. The SIKA VVX is used for the flow measurement of water at medium and high measuring ranges. It is used, e.g, in high-capacity heat pumps and industrial facilities. 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.
