- The rheonics density meter SRD measures viscosity and density by means of a torsional resonator, one end of which is immersed in the fluid under test.
- The more viscous the fluid, the higher the mechanical damping of the resonator. By measuring the damping, the product of viscosity and density may be calculated by rheonics’ proprietary algorithms.
- The resonator is both excited and sensed by means of an electromagnetic transducer mounted in the sensor’s body.
- Damping 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.
