New optical consistency measurement

Valmet OC2W has been developed for stock preparation’s short circulation applications in paper, tissue, and board machines.

Valmet has announced it has launched a new Valmet Optical Consistency Measurement model (Valmet OC2W), which has been developed for stock preparation’s short circulation applications in paper, tissue, and board machines. The cost-effective inline consistency measurement is said to be especially suitable for wet end process monitoring.

The company says Valmet OC2W utilises the total consistency measurement method of the original Valmet Optical Consistency Measurement (Valmet OC) and comes with an added capability of ash content available as a second measured value. Particularly in low-consistency measurements, Valmet says its optical measurements are often the only possible technique to provide reliable results. Valmet OC2W can be easily installed with a measuring probe that enables insertion and removal without special tools or a process stop.

“The application specific models make Valmet Optical Consistency Measurement perform well in most pulp and paper applications. The new Valmet OC2W makes inline optical measurement available for wet end and adds a new option for wet end monitoring technology,” says Heikki Föhr, Product Manager, Valmet Optical Consistency Measurement, Automation Systems business line, Valmet.

Technical information

Valmet OC2W is part of the Valmet Optical Consistency Measurement family, each optimised for use with different kinds of wood pulps and recycled textile fibres. Installed in an area of turbulent flow, the temperature and vibration resistant probes are self-cleaning even in the demanding process environments. Valmet OC2W has been developed to measure ash and total consistency (0-12%) in the challenging wet end environment. Sharing the same basic components and modules, Valmet OC has gained a reputation for accuracy, reliability, and ease of installation.
