Introduction
The Endress+Hauser Proline Promag P 500 is a high-performance electromagnetic flowmeter designed for demanding chemical and process applications with corrosive liquids and high medium temperatures. It supports both integrated and remote configurations, offering accurate, pressure-loss-free flow measurement with advanced communication options, Heartbeat Technology, and wide material compatibility for maximum installation flexibility and operational safety.
Key advantages
High-temperature and high-corrosion resistance: Handles media up to +180°C with PFA high-temperature liner and multiple electrode materials, ideal for corrosive fluids in chemical processing.
Remote configuration with up to 4 I/Os: Offers flexible installation in hard-to-reach areas, with freely configurable I/O functionality for seamless system integration.
Industry-leading accuracy: Delivers ±0.2% o.r. measurement error with optional Flat Spec, supported by 0× DN full-bore design for reliable performance after pipe obstructions.
Comprehensive communication and diagnostics: Supports HART, PROFINET, Ethernet/IP, and WLAN access, with full access to process and diagnostic data via Heartbeat Technology.
Extreme versatility for large-scale applications: Nominal diameter up to DN 600 (24") with multiple housing materials and marine approvals, suitable for a wide range of industrial environments.
