Measurement solutions for pulp and paper applications

Berthold is expert in monitoring critical processes. As technology leader of radiometric measurements we bring benefit to the pulp and paper industry by providing highly accurate and reliable online measurements – the base for a cost-efficient and high-quality production.
Applications are wide ranging from the radiometric level measurement on a pulp digester, over the concentration measurement of green or black liquor, up to the mass flow measurement of recycling paper on conveyor belts. Using microwave transmission technology we provide real-time measurements of the moisture content of wood chips.

These advantages are used to make critical applications more reliable:

Non-contacting: outside mounting of components

Reliable under extreme conditions

Wear and maintenance-free

Easy installation on existing pipes and vessels via clamp-on solutions

Smooth handling and operation

No re-calibration required

Outstanding long-term stability

Virtually no operational expenses

 The processes in which Berthold instruments are used include:

Level and high-level switch in the pulp digester

Pulp stock level in the MC pump standpipe

Mass flow of recycled paper

Blockage detection in the pulper

Mass flow of wood chips or bark

Density of green or liquor

Density of lime mud

Moisture of wood chips

Ash content in the pulp
