The Online Viscosity-Sensor ICMS

The OCM solutions from MicroResonant use a low frequency resonant acoustic sensor element which can simultaneously measure density and viscosity with high accuracy. The vibrating sensor generates a flow profile that penetrates deeply into the liquid, whereby effects of surface adhesion of fluid components are less impairing than with higher frequency sensors such as surface acoustic wave resonators (SAW).
