A Critical Tool for Oil Field Fluids
The Model 5550 HPHT Viscometer is a concentric cylinder viscometer that uses the rotor and bob geometry accepted by the energy industry. Its design meets the requirements set forth in ISO and API standards for viscosity measurement of completion fluids at high pressure and high temperature.
Engineering Excellence for Superior Performance
The small, bench-top Model 5550 is engineered with a number of features that make it both highly accurate and very reliable. The instrument’s temperature control system uses a sliding carbon-block heater which provides precise control while eliminating the oils and circulators associated with liquid high-temperature baths. The rotor drive employs an accurate, high precision speed control system for precise shear rate control. Torque measurements are performed by a highly accurate digital sensor which is external to the sample cell to avoid corrosion or abrasion. The proprietary design of the bob’s shaft serves as a very effective climb arrestor which keeps the sample in the measurement region of the cell and away from critical rod seals and bearings. This
combination of benefits provides better test results while prolonging the life of key components. Should the bob’s shaft bearings need replacing, a user will be pleased to discover that he can replace them in less than ten minutes compliments of the best-engineered design on the market.
Operational Simplicity
The Model 5550 Viscometer is simple to operate. All of the basic operational controls are conveniently located on the front panel. Test schedule programming, control and data acquisition are provided by the Chandler Rheo 5000 software, which operates on an independent computer. The control system provides automatic temperature and pressure profile control, motor speed profiles, and automatic calibration capabilities. The software also features real time displays of test parameters and results. All data is easily exported to a spreadsheet file for archiving and data sharing.
