Pulp & paper instruments: buying guide and questions
How to choose a pulp and paper instrument
- Stock and slurry flow
- Use electromagnetic flow meters with abrasion-resistant liners for pulp stock, filler slurries and white water; slurry-duty meters handle high consistency.
- Chemistry
- pH/ORP sensors with coating-resistant references for headbox, bleaching and effluent; toroidal conductivity sensors for liquors and caustic concentration.
- Pressure and level
- Pressure transmitters and submersible level sensors for chests, tanks, steam and hydraulic systems; flush diaphragms for fibrous media.
- Steam and utilities
- Temperature sensors and transmitters, dew-point and humidity instruments for dryers and compressed air.
- Maintenance
- Calibrators, test pumps and precision thermometers keep the mill's instruments accurate.
Which flow meter is best for pulp stock?
An electromagnetic flow meter: it has no moving parts or obstruction and is not affected by fibre. Choose a liner and electrodes suitable for the consistency and chemicals.
How do I keep pH sensors working in a paper mill?
Choose sensors with poisoning-resistant or rebuildable references and flat glass, mount them where they stay wet and clean, and calibrate regularly; retractable sensors allow cleaning without shutdown.
Do you supply complete instrument packages for paper mills in Bangladesh?
Yes. Send the instrument list or P&ID and we quote suitable models from Rosemount, Keller, WIKA, Endress+Hauser, Dwyer, Druck, NOSHOK and APG and other makes within 24 hours.
