- The rheonics density meter SRD measures viscosity and density by means of a balanced torsional resonator, one end of which is immersed in the fluid under test.
- Density of fluid is measured through the shift in resonant frequency of the resonator.
- The more viscous the fluid, the higher the mechanical damping of the resonator. By measuring the damping, the product of viscosity and density is calculated by rheonics’ proprietary algorithms.
- Density and viscosity of fluid is measured by the rheonics patented sensing and evaluation electronics and stable, high accuracy and repeatable readings are obtained based on rheonics’ proven gated phase-locked loop technology.
