FAQ - Technology

In 1981, Sofraser patented the first viscometer maintained in vibration at its resonance frequency.
More than 30 years later, we still use this technology because it has been proven to be the best for process viscosity measurement.>

>It is the natural vibration frequency of a mechanical system (like a diapason). The resonance frequency allows a system to oscillate with the the greatest amplitude of a vibration. In our system, the amplitude of the vibrating rod is about 0.1 mm.>

No. The viscometer vibrating at resonance frequency is not affected by external vibrations and disturbances.>
