Vortex flow meters

The SV range flow sensors monitor hydrous media and reliably detect the volumetric flow quantity. For more demanding tasks, sensors which can measure both the volumetric flow quantity and the medium temperature are offered. They are frequently used in cooling circuits, e.g. in steelworks, the automotive industry and in glassmaking.
The sensors operate to the vortex measuring principle. Behind a blunt body (or shedder) integrated in the measuring pipe, the flowing medium generates swirling vortices depending on the velocity. These vortices are a reliable indicator of the flow rate. The vortex principle is virtually independent of pressure and temperature fluctuations of the medium.
The current flow is output as an analogue signal, the temperature as a Pt1000 signal.
