ifm efector SV type vortex flowmeters

Behind a bluff body integrated in the measuring pipe, the flowing medium generates swirling vortices depending on its velocity. These vortices are detected by a piezoceramic sensor. If the cross-section is known, the number of the vortices allows determination of the flow rate. This flow rate measurement principle, known as vortex principle, is virtually independent of pressure and temperature fluctuations of the medium.

The SV type vortex flowmeters are suitable for use in cooling water circuits. They can be used for water with and without conductivity. The current flow and temperature are output as standardised current signal (4–20 mA), as a frequency signal, a switching output or via IO-Link as an option.

These space-saving devices from ifm efector inform the user quickly and clearly about the current volumetric flow. The multicolour display can be rotated electronically and the red/green colour selection for process values can be set. Installation can be independent of orientation due to the rotatable G and R process connections, which are optionally available. In addition, the SV flowmeters come with an integrated temperature measurement.
