Vortex Flow Sensors How it works: Behind a flow around the bluff body arise opposite and mutually offset vortex. The vertebrae dissolve on the Edge of the bluff body and form a Kármán vortex street in the flow. The distance between the individual vertebrae is constant. The frequency with which the vortexes flow past a sensor depends on the flow velocity and proportional to the flow. The transducer detects the vortices, these are converted into an electrical frequency signal. Features Vortex flow sensors: Flow sensor without moving parts for water no mechanical wear. Stable, glass fiber reinforced plastic ensures maximum durability and performance. Completely encapsulated piezoceramic sensor for detecting the vortex thus no direct contact with the medium. Wide span (up to 1:21). Integrated temperature sensor. Output signals: An analog voltage signal and / or a frequency signal are available for the flow and a resistance or analog signal for the temperature. High immunity to interference. Media-contacting components metal-free. Traceability via serial number. Threaded connection or QuickFastening.
