Measurement Solutions for Pulp and Paper Processing
Reliable non-contact level and density measurement for black liquor, green liquor, digesters, and stock processing applications.
Explore industries by the type of process environment and material challenges commonly encountered:
Common Pulp and Paper Processing Applications
| Application | Typical Measurement |
| Digesters and blow tanks | Continuous Level |
| Black liquor evaporators and storage tanks | Continuous Level, Density |
| Green and white liquor processing vessels | Continuous Level, Density |
| Pulp stock preparation and blending systems | Density, Mass Flow |
| Stock chests and machine chests | Continuous Level, Density |
| Recovery boiler feed and related process vessels | Level, Density |
What makes accurate measurement challenging?
- Foam and agitation create unstable measurement conditions
- Density and consistency change throughout the process
- Steam, chemicals, and buildup reduce sensor reliability
How Radiometric Measurement Solves Common Pulp and Paper Processing Measurement Challenges
Contact instruments are affected by fibrous stock, coating, and buildup →
External measurement, no contact with pulp stock or process fluid
Caustic chemicals and harsh liquors reduce sensor life →
No wetted parts exposed to corrosive process media
Changing consistency and difficult process conditions affect reliability →
Stable measurement despite changing pulp and liquor conditions
Buildup on probes causes false readings and maintenance issues →
Unaffected by coating, scaling, and internal buildup
Maintenance in continuous operations can be disruptive →
Minimal maintenance with less interruption to paper production
