Overcoming Pulp and Paper Measurement Challenges

Accuracy in High Solids and Fouling Conditions

Pulp and paper processes are known to be abrasive at high temperatures with wide pH ranges. These conditions quickly foul sensors, slow response time, and introduce measurement drift.
Our sensors are designed for harsh environments. Specialized pH glass recipes and a rugged reference system ensure measurement integrity.

Reducing Maintenance in Dirty Processes

Frequent cleaning and calibrations are common in pulp and paper mills. Maintenance teams are already stretched across large facilities, and manual sensor upkeep increases downtime and labor demand.
Memosens technology enables predictive maintenance through onboard sensor diagnostics. Operators and maintenance teams can monitor sensor health, calibration status, and remaining useful life directly from the control system.
LET'S PREDICT MAINTENANCE

Process Variability Across Multiple Stages

From wood digestion to bleaching and stock preparation, pulp and paper processes use multiple chemical stages that must stay within tight limits. Measurement reliability impacts product quality, chemical consumption, and equipment performance.
M4 Knick provides stable, real-time measurement with fast response sensors and digital communication. Memosens technology ensures consistent data transfer to the DCS, allowing operators to make adjustments quickly.

Lab & Process Measurement Solutions

Process control in pulp and paper is closely tied to lab verification. Grab samples are often used to confirm inline measurements, especially in critical stages like bleaching and chemical dosing. Alignment between lab and process data is essential for maintaining quality and compliance.

Memosens sensors are calibrated in the lab and installed without recalibration, reducing variability and improving efficiency. Standardizing measurement technology across the plant provides:

Bullet point

Calibration traceability with stored sensor data

Bullet point

Simplified training and reduced operator error

Bullet point

Standardization of your measurement technologies in the lab and the field

Application Examples

Cooling Tower Corrosion Monitoring

Cooling towers require an acid addition like sulfuric for pH adjustment to dissolve the calcium carbonate buildup from high salts in the system.
