Electromagnetic Flow Measurement in Bio-based Materials Processing 🌱

In a straw comprehensive utilization industrial park project (Phase I, 20,000 t/a), electromagnetic flowmeters play a critical role across the entire process—covering pretreatment, mild hydrolysis, separation, utilities, and environmental treatment.

Designed to handle fiber-containing slurries, weakly corrosive medium, and large-diameter pipe systems, electromagnetic flowmeters provide accurate and stable flow data for material–water ratio control, solvent dosing, energy accounting, and environmental compliance. Integrated with DCS systems, they support precise control of mild hydrolysis (120-160 °C), enabling high cellulose purity and efficient hemicellulose extraction, while also helping achieve ≥95% process water reuse and zero-waste utilization.

This project demonstrates how proper instrument selection and process-oriented configuration of electromagnetic flowmeters can translate advanced laboratory bio-based technologies into stable, scalable industrial production—offering a replicable reference for future straw high-value utilization projects.

Pressure Transmitters: Safeguarding Marine Systems

On modern ocean-going vessels, pressure transmitters have become the core sensory organs of intelligent ballast water management. By delivering real-time, high-accuracy liquid level data, they support vessel stability calculations, help prevent capsizing risks, protect hull structural integrity, and improve overall operational reliability. Designed to withstand harsh marine conditions—corrosive seawater, vibration, sedimentation, and hazardous areas—specialized pressure transmitters enable precise ballast adjustment, faster emergency response, and fuel efficiency optimization of up to 3–8%. From tank bottom level monitoring and high/low alarms to pump control and flooding detection, reliable pressure monitoring is fundamental to safer, smarter, and more efficient marine operations.
