OPERATING PRINCIPLE
  • The rheonics SRV viscometer measures viscosity 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.

Balanced Resonator

Unique patented co-axial resonator. High immunity of external vibrations and shocks.

Direct Mounting in tanks/pipes

Two ends of the sensors twist in opposite directions, cancelling out reaction torques on their mounting

Extended Mount

Insert sensor to the middle of flow in large tubes or in deep tanks. No limit to insulation depths.
