Abstract

We recently presented a robust viscosity measurement system based on a torsionally oscillating pipe. This resonant sensor consists of two concentrically aligned pipes. The outer pipe acts as an oscillating torsion spring while the inner one remains at rest. At both ends of the pipe flywheels are located, oscillating against each other in the torsional mode. The pipe is filled with a fluid, which is causing additional damping related to its viscosity. In this contribution we present the sensor setup, describe the measurement principle and analyze the viscosity measurement accuracy achieved in test measurements for different viscous fluids.
