Consistency Transmitters

Valmet Microwave Consistency Transmitters available from Cross Company Process Instrumentation & Valves is the ultimate device for measuring and controlling total consistency in pulp and paper processes. It uses patented microwave-based technology, which allows it to measure total consistency independent of the fiber length, freeness, wood species or blend present in the process stream. Solids such as fibers and fillers conduct microwaves faster than water so that shorter microwave transmission times will correlate to higher consistencies. This relationship is linear, making it is easy to calibrate the device regardless of what is being measured. Broken, recycled fiber, or other difficult pulp, is handled without a problem.

The Valmet MCA is simple to install: no high-voltage motor, motor starters, special cables or seal water installation is necessary. Therefore, it does not require regular maintenance, and it keeps commissioning and running costs to a minimum.

The consistency transmitter portfolio has been built on half a century-long path of innovative development, migration of unique technologies and close customer co-operation. Valmet is today the leading pulp consistency transmitter supplier worldwide.

The portfolio also includes conductivity and concentration measurement products which are well established in the industry. Their proven and tested technology in demanding process industry applications have a strong and leading role in many measurement and control applications in pulp and paper, chemical, power, pharma, and food industries.
