Density measurement in liquor recovery

Process data

Measuring task:
Density measurement
Measuring point:
Measuring range up to:
Cooking liquor
Process temperature:
+120 … +130 °C
Process pressure:
+2 … +3 bar
Special challenges:
The liquor contains organic residual substances


The black liquor resulting from pulp cooking is regenerated and fed back into the digester. Liquor regeneration comprises several process steps. The processes take place at high temperatures and pressures; the media are aggressive and sometimes abrasive. Density measurement of the liquor in the pipelines is required for eco-friendly and energy-efficient process control.
