Operating frequency selection
The sensors of the measuring device are available with adapted operating frequencies. For
the resonance behavior of the measuring pipes, these frequencies are optimized for
different properties of measuring pipes (material, pipe wall thickness) and media
(kinematic viscosity). If these properties are known, an optimum selection can be made
according to the following tables
Measuring pipe material Nominal diameter of measuring

< DN 65 (2½")
Steel, cast iron
