Pulp, Paper & Packaging
Process and wastewater instrument calibration for paper and packaging mills
Paper and packaging mills move large volumes of stock, water, and chemicals, then treat what leaves the site. We calibrate and repair the flow, pressure, level, and analytical instruments across that process, from stock preparation to effluent treatment.

Where calibration shows up
From stock preparation to effluent treatment
A mill is several processes in one. Each has instruments working in wet, dirty, or high-solids service.
Stock and process flow
Magnetic flow meters on stock, white water, and filtrate lines, where consistency and solids make measurement harder.
Pressure and level
Pressure transmitters and level instruments on headboxes, chests, and tanks that keep the process stable.
Chemical dosing
Metering flow and analytical instruments that control additive, bleaching, and treatment chemical feed.
Wastewater and effluent
Flow, pH, and dissolved oxygen instruments in mill wastewater treatment, often tied to discharge permit reporting.
Common instruments
Instruments we calibrate and repair for this work
Mill instruments see moisture, fiber, and chemicals every day. These are the device types we service most often in pulp, paper, and packaging plants.
Services
What we handle, from first check to replacement
Mills often plan maintenance around scheduled shutdowns. We can work during those windows or calibrate accessible instruments while the mill is running.
On-site calibration
Calibration of process and wastewater instruments at the mill, organized by area to fit shutdown and maintenance schedules.
Verification
Documented checks on effluent flow and analytical instruments for mills that maintain discharge records.
Troubleshooting
Diagnosing noisy flow signals in high-consistency stock, pressure readings affected by plugging, and analyzer drift.
Repair
Repair of meters, transmitters, and analyzer electronics, followed by calibration before the instrument returns to service.
Equipment sales
Replacement meters and transmitters suited to fiber, solids, and the chemicals used in your process.
Calibration program
Why calibration matters
Mills measure the materials they buy, the product they make, and the water they return. Each measurement has a cost when it is wrong.
01
Accuracy
Chemical and fiber usage add up quickly at mill volumes. Calibrated instruments keep usage figures and recipes reliable.
02
Reliability
Fiber buildup and wet conditions are hard on sensors. Regular calibration finds wear and fouling before readings fail.
03
Reduced downtime
Calibrating during scheduled shutdowns keeps instrument work from extending an outage or stopping a machine.
04
Documentation
Calibration certificates support environmental reporting and maintenance records, and are available in the online portal.
