Introduction
The Endress+Hauser Proline Promag 55S is a robust electromagnetic flowmeter purpose-built for inhomogeneous, abrasive, and corrosive fluids in demanding industries like pulp & paper, mining, and wastewater. It offers integrated solids content diagnostics, high abrasion resistance, and multi-protocol communication for reliable, low-maintenance flow measurement.
Key advantages
1. Extreme abrasion resistance: Features industry-optimized liners (polyurethane, rubber) and electrodes, built to handle fluids with up to 80% solids by weight.
2. Integrated solids content diagnostics: Unique signal processing enables accurate flow measurement even in high-solids, abrasive slurries without additional sensors.
3. High-performance signal stability: Intensified coil system and electrode cleaning ensure reliable operation in harsh environments, reducing downtime and maintenance.
4. Wide material compatibility: Offers multiple liner and electrode options (alloy C22, tungsten carbide, tantalum) for corrosive and abrasive fluid applications.
5. Multi-protocol integration: Supports HART, PROFIBUS PA/DP, and FOUNDATION Fieldbus, enabling seamless integration into industrial control systems.
