When dealing with non-Newtonian fluids (slurries, polymers, or crude oils), viscosity changes with shear rate. The Expert 46’s advanced model adjusts its algorithm on the fly, providing accurate viscosity-at-flow data that lab rheometers cannot replicate in situ.

A: Yes, but you must use the optional high-temperature sensor ring (rated to 400°C). The standard model handles up to 120°C.

The manufacturer recommends a "Zero-Flow Verification" every six months. This involves placing the sensor ring in still air or a closed valve section and pressing "Auto-Zero." The device uses a solid-state reference to self-calibrate. Full factory recalibration is only required every 2,000 operating hours or two years, whichever comes first. The ruggedized case requires no special cleaning—simply wipe with a damp cloth.
