OPERATING PRINCIPLE

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.

Analysis and Acquisition Softwares

Insensitive to Mounting Conditions

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.

Process Viscosity Monitoring, Storage & Analyzer

Powerful, intuitive GUI with measurement acquisition, analysis & logging.

On-device(edge), cloud and PC data acquisition and analysis

API for data acquisition and integration in customer applications

Ruggedised electronics deliver accurate, fast and reliable measurements

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.
