Introduction
The Endress+Hauser Proline Prowirl D 200 is a compact, wafer-style vortex flowmeter engineered for cost-effective, reliable flow measurement in basic process applications. Designed for direct flange mounting with minimal installation costs, it handles wet/saturated/superheated steam, gases, and cryogenic liquids, while enabling seamless replacement of orifice plates. Integrated temperature measurement supports mass/energy flow calculations, and Heartbeat Technology ensures continuous process safety and verification, making it ideal for auxiliary processes and hazardous areas with SIL approvals.
Key advantages
1. Integrated Temperature & High Accuracy: ±0.75% liquid/±1.00% gas flow error, with built-in temp sensor for saturated steam mass/energy flow calculations, eliminating extra instrumentation.
2. Robust & Low-Maintenance Design: Drift-free capacitive sensor withstands vibrations, water hammer, and -200 to +450°C temperatures; no moving parts reduce wear in industrial environments.
3. Flexible Installation & Compact Footprint: 65mm face-to-face wafer design with included centering rings enables fast, flange-mounted setup; low weight suits space-constrained auxiliary processes.
4. Comprehensive Digital & Safe Operation: 4-line touch display with background lighting (no device opening needed) supports HART/PA/FF/APL comms, plus Heartbeat Technology for in-situ verification.
5. Global Approvals & Wide Process Range: SIL compliance, ATEX/IECEx hazardous area certifications, and marine approvals (ABS/DNV/CCS) support use in diverse industrial sectors worldwide.
