OPERATING PRINCIPLE

The rheonics DVM 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.

Single instrument, dual function

Rheonics’ DVM is a unique product that replaces two alternatives and offers better performance while operating at true reservoir conditions. It eliminates the difficulty of co-locating two different instruments in any application needing density-viscosity monitoring of the process fluid.

Minimal sample size requirement

Minimal reservoir fluid is used for testing in the DVM since there is no requirement of a separate line or sampling system. Safe and cost-effective to operate, DVM requires only 0.7ml of sample to measure viscosity and density across the complete P,T range saving time and money.
