- The rheonics high accuracy density meter and viscometer DVP measures viscosity and density by means of a torsional resonator, which is fully 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 denser the fluid, the lower the resonant frequency. A denser fluid increases the mass loading of the resonator.
- 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.
Sophisticated, patented 3rd generation electronics drive these sensors and evaluate their response. Ultra-fast and robust electronics, combined with comprehensive computational models, make DVPs one of the fastest and most accurate in the industry. DVP gives real time, accurate density and viscosity measurements every second and is not affected by flow variations!
