- The rheonics SRV fluid 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.
Sophisticated, patented 3rd generation electronics drive these sensors and evaluate their response. Ultra-fast and robust electronics, combined with comprehensive computational models, make SRVs one of the fastest and most accurate in the industry. SRV gives real time, accurate viscosity measurements every second and is not affected by flow variations! Embedded temperature sensor gives instantaneous inline fluid temperature.
