Getting rheological data that mimics subsurface conditions above 15,000 PSI and/or 200°C can be a challenge with conventional rheometers. The Cambridge Viscosity ViscoLab PVT+ offers a solution to this challenge by providing shear rates with the viscosity measurement and a shear sweep function to collect data at multiple shear rates within a single test. The PVT+ has options for measuring at pressures in excess of 30,000 PSI (or higher upon request), temperatures to 315°C, and viscosities as low as 0.02cP, which is well beyond the capability of commercially available, HPHT rheometers.

Boston—Machinery failures, downtime and maintenance labor costs can kill a refiner’s bottom line profits.  A major US oil company with refinery installations in North and South America has installed several Cambridge Viscosity VISCOpro viscometers to monitor oil viscosity, providing engineers with real-time information on oil quality. The viscometers utilize Cambridge’s 392 process sensors and are Class 1 Div 1 Group B, C, and D certified.

Cambridge Flanged Viscometer Registered in ABSA Program

Boston—Cambridge Viscosity’s flanged viscometer, or SPL/C 392 sensor, has been accepted for registration in the Alberta Boilers Safety Association (ABSA) Design Registration Program. This designation certifies that the sensor design complies with the Safety Codes Act.

“Being accepted into ABSA’s program certifies that the SPL/C 392 sensor can be used in high pressureenvironments up to 1400 PSI,” says Cambridge Director of Engineering Daniel Airey. “This sensor is particularly effective for marine fuel, oil pipelines and refineries.”

The SPL/C 392 in-line viscometer provides continuous, real-time measurement of temperature and viscosity.  The sensor’s patented technology is based upon a simple, reliable electromagnetic concept. Two coils pull a piston back and forth within a constantly refreshed sample of process fluid. Proprietary circuitry analyzes the piston’s travel time to measure absolute viscosity. A built-in resistance temperature detector (RTD) senses the actual temperature in the measurement chamber.

Measurements can be made in any of the 13 different 20:1 viscosity ranges, covering a span of 0.2 to 20,000 cP. The sensor is designed with a four-bolt stainless steel SAE Code 61 flange and is easily installed in pipelines ranging from 2” and larger. The sensor’s self-cleaning feature provides for low-maintenance and ease-of-use across applications.
