How it works
The Rheonics SRV fluid viscometer measures viscosity via a torsional resonator. A torsional resonator has one end immersed in the fluid under test. The higher the viscosity of the fluid, the higher the mechanical damping of the resonator. By measuring the attenuation, the product of viscosity and density can be calculated using Rheonics’ proprietary algorithm.
The resonator is excited and detected through an electromagnetic transducer mounted on the sensor body. Damping is measured with Rheonics’ patented sensing and evaluation electronics, which achieve stable, high accuracy and repeatable readings based on Rheonics’ proven gated phase-locked loop technology.
