Level Measurement For Paper Mills And Pulp Processing
Paper mills and pulp processing plants require reliable level measurement for pulp tanks, wood chip silos, bleaching tanks, wastewater basins, chemical dosing tanks, slurry vessels and process storage systems. SHAO provides level measurement solutions for pulp, paper slurry, fiber materials, process liquids and wastewater treatment applications.
Why Paper Mill Level Measurement Requires Reliable Process Control
Paper mills handle both solid materials and liquid process media. Wood chips, fiber powder and pulp behave differently from clean liquids. Pulp tanks and slurry vessels may contain foam, suspended fibers, agitation and buildup, while wastewater basins may include sludge, chemicals and fluctuating liquid levels. A suitable level measurement solution should consider material type, tank structure, process temperature, foam, viscosity, installation position and control purpose.

Main Challenges In Paper Mill Level Measurement
Paper production environments often involve pulp, foam, fibers, slurry, chemicals and wastewater. These conditions can affect measurement stability and sensor lifetime.
Pulp and slurry may be viscous and contain suspended fibers.
Foam and agitation may affect signal stability.
Wood chips and fibers may form uneven material surfaces.
Process chemicals require material compatibility consideration.
Wastewater basins may contain sludge, foam and floating materials.
Production lines need reliable output signals for automation control.

Frequently Asked Questions
What level sensor is suitable for pulp tanks?
Radar level meters or pressure level transmitters can be considered depending on foam, viscosity, agitation, tank size and installation condition.
Can radar level meters measure paper slurry?
Yes. Radar level meters can be used for many slurry and pulp applications because they provide non-contact measurement. Foam and agitation conditions should be confirmed before selection.
Which solution is suitable for wood chip silos?
Wood chip silos may use radar level meters for continuous measurement or solid level switches for high-level and low-level alarm.
How does foam affect pulp tank level measurement?
Foam may weaken or disturb the measurement signal. The correct sensor type, installation position and signal processing should be selected based on the foam condition.
What information should I provide before requesting a quotation?
Please provide medium type, tank or silo size, measuring range, foam or agitation condition, installation method, output signal requirement and site photos if available.
