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.
Model 5550 offers computer controlled unique technology and houses a sliding carbon dry-block heater and a high-precision digital torque sensor that is external to the sample cell.
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 climb arrestor helps keep the sample fluid in the measurement area of the rotor. This protects critical parts such as bob shaft bearings from contamination, prolonging bearing life and decreasing the maintenance intervals. When the bob shaft bearings need replacing, the process to replace them can be accomplished in under 10 minutes with minimal effort and tools.
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.
