Introduction
The Endress+Hauser Proline Promag P 200 is a loop-powered electromagnetic flowmeter engineered for demanding chemical and process applications with corrosive liquids and high medium temperatures. It combines accurate, pressure-loss-free flow measurement with intrinsically safe design, Heartbeat Technology, and wide material compatibility, ensuring reliable performance in hazardous and challenging industrial environments.
Key advantages
1. High-temperature, corrosion-resistant design: Handles up to +150°C media with PFA/PTFE liners and alloy electrodes, ideal for corrosive fluids in chemical processing.
2. Loop-powered operation: Eliminates the need for separate power supplies, enabling seamless integration into existing infrastructures with minimal wiring.
3. Maintenance-free & pressure-loss-free: No moving parts and full bore design reduce downtime and operational costs, with no impact on process flow.
4. Intrinsically safe & globally approved: Certified for hazardous areas with SIL compliance and worldwide approvals, ensuring maximum plant safety.
5. Integrated verification with Heartbeat Technology: Enables continuous process safety and traceable verification without process interruption.
