The Valmet Rotating Consistency Measurement (Valmet Rotary) for pulp and paper producers provides a transmitter that offers highly accurate fiber consistency measurement for critical applications.
With a mechanical design and an electronic solution for reliability, its high sensitivity and simplified design make on-site maintenance easier and faster for low overall lifetime costs.
Based on shear force measurement technology, the tool has excellent performance in challenging environments with high temperature, high pressure, and abrasive chemicals. A modular design secures a universal use covering consistency range from 1.5 to 16%. It can be installed to pipe sections where other shear force sensors can't work.
The strong motor ensures trouble-free startup and reliable mixing in unfavorable process conditions. A complete range of sensing elements across the entire measurement range secures near-universal application.
Commissioning, calibration, and operation are enhanced with the Valmet Link user interface, a flexible platform with secure remote connection possibilities. With a graphical display and a clear menu structure, setup and operation are fast and easy. The user interface and big display enable easy calibration and give an overview of calibration data. The user interface is also prepared for different communication protocols and can be updated for future functionalities.
