OPERATING PRINCIPLE
  • 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.
