The Model 50 High-Temperature High- Pressure Rheometer is a rotational viscometer designed for testing fluids at temperatures to 500°F (260°C) and pressures to 1,000 psig (7,000 kPa) in a coaxial cylinder chamber. Heating and rotor speed are controlled by input from specialized software.
Fann’s xpRt50™ software is optimized for use with drilling fluids and fracturing fluids, and is designed to allow a single computer to control two Model 50 Viscometers using RS-485 serial communications. Once the sample has been loaded and the heater bath raised for testing, all control of the viscometer is accomplished via the computer and the specialized software.
