Technology

The Marimex ViscoScope process viscometer is based on a sensor connected to a transmitter via a transmission cable. The sensor is driven by the transmitter, which stimulates it to an oscillating torsion at a small amplitude. A fast closed loop PID controller maintains the resonance frequency of the sensor at a constant level. Thus as viscosity increases, so does the power required. This property can be used to measure the dynamic viscosity in mPa•s x gr/cm³ (η x ρ). The inline viscometer is ready for immediate use and responds to viscosity changes in less than 2 seconds.

The probe’s torsional oscillation generates a shear wave with a low penetration in the liquid allowing the smallest differences in viscosity to be detected even under challenging process conditions.
