Valmet launches new optical consistency measurement for wet end applications

Valmet has launched a new Valmet Optical Consistency Measurement model (Valmet OC2W), developed for stock preparation’s short circulation applications in paper, tissue and board machines. According to the company, the “cost-effective inline consistency measurement” is especially suitable for wet-end process monitoring.

Valmet OC2W reportedly utilizes 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’s optical measurements often provide reliable results where needed. Valmet OC2W can be installed with a measuring probe that enables insertion and removal without special tools or a process stop.

Valmet OC2W is part of the Valmet Optical Consistency Measurement family, each optimized 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 percent) in the challenging wet end environment. Sharing the same basic components and modules, Valmet OC has gained a deserved reputation for accuracy, reliability, and ease of installation.
